I'm surprised I didn't see discussion of the concept of traveling directly downwind faster than the wind here. The linked article has great examples of closed minded "educated" people declaring that something is impossible, and dismissing evidence as a hoax. I'm not sure there is any direct application, but the concepts and thinking involved to understand how this works seem likely to inspire some really useful invention some day. There's another good article is at Make magazone which includes a link to the earlier article they ran where they "debunked" the claims. http://blog.makezine.com/2010/11/04/downwind-faster-than-the-wind-black/

Enjoyed your electric charge detector article. But not sure about the statement "it really takes no energy to turn off the FET". Surely the electrostatic field results in a force on the electrons, which move aside as a result. Force x distance moved = work (energy expended). The net electrostatic potential is slightly reduced as the electrons are now further away from the gate. Or am I misunderstanding this?

My mind works in a visual fashion. This has advantages as well as disadvantages. If I can visualize what is happening in a system at the most fundamental level, I can learn "the rest" very easily, even predicting effects before I am told about them. On the other hand, if I try to learn about something without being given what I need to visualize what is going on underneath, the lesson seems arbitrary and I end up having trouble remembering it. The lessons here seem like they were written for me. I came here in search of a better understanding of transistors and now I have one (at last!). I am now going to read every word on this website, being fairly sure that I will come out with a stronger understanding of every concept I read about here. Well done, well done, well done!

Hello, you have a lot of info on microwave ovens and magnetrons. I am wondering if any data exists on "smelting metals with a microwave." some one over at open source ecology said that putting a barrier between the metal like silicone-carbide, will capture and turn the microwaves into heat that can then be transferred to the metal through convection. if you want a link to the forum page that the statement was made, email me directly. I will send them then, until then I do not want to spam links here.

I was force-fed so much theory and so many equations throughout my electrical engineering degree that I'd failed to fundamentally understand the meaning of some of it. Interestingly enough, I've gotten away with not understanding the meaning for the past several years. Recently I decided to build some training material for non-electrical engineers to explain some "electrical energy" concepts. I found that while I could do the math, I couldn't completely explain what was going on. The material and links on your site are helping me bridge some of the gaps inside my own head. Thank you for your time and energy and your simple yet complete way of explaining things :)

You seem to be ones who would support efforts to get free energy "out in the open." And so I write You in the hopes that You can help in My effort to do so. If this is of interest, please pass the word along! A petition has been started on Change.org for the US Government to release electrogravitics to the public. http://www.change.org/petitions/us-military-release-the-technology-of-electrogravitics Why This Is Important My early childhood was defined by My father's excitement for His work in electrogravitics, then (1950's) being worked on openly by all major aerospace companies. My father, a CalTech graduate and one of the top electrical engineers at one of these companies, would tell Me about the successes of His experiments (gravity control and overunity (free energy)), and tell Me what the world I would grow up in would look like. Cars would fly, cities would float, and We would have all the energy We could use. Then, one night He came home from work late and woke Me up to tell Me We couldn't talk about the flying cars, the floating cities, the free energy anymore. "They want it secret for now." Since My childhood, I have studied economics, coming to the conclusion (later confirmed by Jeremy Rifkin in His book, Entropy) that all money represented was meaningful energy expended. One can grasp this most easily by considering the first hunter, fisherperson, gatherer, farmer, miner. The stuff They gained/used was free: critters, fish, fruits, vegetables, nuts, seed, sun, soil, rain, ores. It was the meaningful energy expended that gave "value" to the stuff: the killing, fishing, picking, tilling, weeding, harvesting, mining, transporting. Add abundantly what money represents - energy - and the need for money (and the control of others it affords) in all its forms (barter, trade, work exchange, coin, bills, electronic funds...) will dissipate and what is left is free. Add robots to do all the necessary jobs no One wants to do to free energy, and Humans will be freed to follow Their bliss - within the three Laws: Do not willfully hurt or kill another Being Do not willfully take or damage another Being's property Do not willfully defraud another Being (A Being (cap the "B") is sentient, sapient; animals are beings) Waste would be virtually eliminated: supermarkets presently throw out hundreds of thousands of tons of food a month! Distributing by need and not profit will end this waste. Products would be made to last instead of being designed to break so as to ensure future sales. Theft-protecting packaging would be unnecessary. And so on. Organic farming would be prized and GMO (genetically modified organisms) would be eliminated. Motive for war will be virtually eliminated. With no profit motive for war suppliers and "infrastructure rebuilders," wars will not be instigated to ensure profits. Poverty will not exist. Hunger will be eliminated. Education (at all levels) will be free for all. Replace the work "ethic" (a slave's ethic: enrich the rich with Your Human energy) with a Betterment Ethic and the Humans who better things will be paid in appreciation, status, name-recognition and Self-satisfaction, the new "coin." Create a central website where problems can be brought up locally and People can “vote” to bump a problem up, down, show apathy by not voting, and chime in with solutions (which can be cheered and booed). Issues will drop off after the original poster indicates that the problem has been resolved or withdrawn, or there has been no activity after, say, six months (that is not set in stone). Social responsibility will be defined as spending 15 minutes a day examining issues on this site. Also, issues with some set number of bumps up will be considered issues that need a wider awareness and go to regional sections. From there, continental, perhaps, and then global, as more are needed to be involved in solving the problem. Problems will beget the awareness to solve them. Without money as a motive, problems will be solved more creatively, directly, harmoniously, and within the three Laws. Leaders of the moment will emerge from this to solve problems as they arise. Open-source all public works programming. This allows for many to make suggestions for betterment, and ensures that no one will create outside the three Laws. It also eliminates “back doors,” and other surreptitious software segments that bog down the clean functioning of the program. Without money as a motive, programmers will be proud to offer Their work for scrutinization and use, openly and freely. Status will be gained for creating the best programs. Though this will not create a utopia, it will be vastly better than what We now have, in this scarcity-defined system, on this planet. ______________________ I have found many who have said They would sign, but They fear being "put on a list." This is the very thing the power elite count on. I say... Cast away fear! Stand and be counted as One who would oppose Them. In the long run, We will overcome - IF We stop allowing fear to be used as Their weapon against Us! So... To any who read this, ask Yourself, "Will I empower the power elite to control Me with fear?" And then give strong consideration to signing this petition. Twitter: @AmaterasuSolar

I began experiencing strange unexplained phenonmena after I was struck by lightening twice some 35 years ago. electronic things frequently won't function around me. For example. Cable boxes often won't function, Light bulbs oftenr go out, street lights blow as I drive by and the wired thing is the distance at which they blow is almost always the same. I am not doing anything consciously to have this happen. When a friend questioned me about my ability he challenged my to put a light out on the side of a restaurant. I had never really tried to consciously make a bulb go out, but this time I concentrated and sure enough it went out. Computers and cell phones I use aften don't work properly. My daughter has the same issues but not my son. Can people inheret thing phenomenon? Surely the science community has to research this strange thing

Hello! On your website you say: "If we place a Potential Difference across either air or a vacuum, no electric current appears. Air and vacuum are insulators. This is sensible, since there are few movable charges in air or vacuum, so a voltage placed across them is unable to cause an electric current. If we place a voltage across a piece of metal or across a puddle of salt water, the charges present in those materials will flow, and an electric current will appear, since these substances are always full of movable charges, and therefore the "voltage pressure" causes the charges to flow." I think you are missing one critical piece of the puzzle here. Someone could read your argument and ask, "well then, why don't the electrons that are on the metal terminals of the voltage supply (which is making the potential difference in the first place) simply jump off the terminals,
[That's just electrical breakdown, a vacuum-arc. Easy to produce if voltage is high enough. But any vacuum that's full of electrons ...isn't a vacuum. (You're right, I don't go into details of *why* insulators are insulating, how is diamond electrically very different than plastic, etc.) -billb]
sail through the vacuum, and reach the other side? The reason this doesn't happen is that any electrons are bound to the metal... and WHY are they bound to the conductor? Ultimately it's the protons of course... But one could then say, well LOOK, if the negative terminal has a net overall negative charge then won't the effect of the protons be somehow canceled out by the the effect of the electrons? the answer lies in electrostatic induction. As soon as an electron leaves the metal it induces a positive charge LOCALLY (think image theory)... the force due to this induced positive charge is much STRONGER than the force due to all the electrons in the metal simply because the induced positive charge is closer... Hence an electron can't simply jump across the terminals of a battery. If one does than it induces a positive charge which sucks it back in.

I ran across this page by chance...I am one of those people who, for whatever reason, sucks the life out of electronic devices. : ( I just sent off my new macbook pro for the second time in four months to get a new logic board, and the backup computer has started freaking out on me since I started using it more regularly this week. This has happened all of my life. I burn through laptops, hard drives, etc like a forest fire. I actually understand computers very well (I am a web dev) and I do nothing that I shouldn't but I can't seem to work on them for any significant length of time without somehow overwhelming them. This also applies to watches, which I cannot wear, and small electronics. Do you suggest that I wear some kind of metal bracelet to ground myself while I work on my computer? I have spent a small fortune on computers and computer repairs, and I have to figure out something. Thanks!

Puzzled about what I saw. In brief:(10:30pm good weather, mid-summer, 2002) At a point 150' south from my location standing outside and 35'above the ground I caught site of a glowing soccer ball sized slowly falling light sphere comprised of a gold grapefruit sized center surrounded by shells of different colors approx 7 colors-(each color was glowing vivid pastel in nature) in all that made up the total physical size of the sphere..(My view of the sphere was akin to slicing the sphere in half and seeing it as a cross section even though it was a round ball) The sphere was dropping a steady stream of gold sparks straight down at a free-fall rate to the ground. The sphere fell slowly to the ground in an arced trajectory and then vanished as it contacted the ground. The total time of this event I witnessed was 3-4 seconds. It took the sphere 3-4 seconds to descend from a height of 35' till it reached the ground. –Note- 35’ was the estimated height at which I first caught sight of the sphere as I had just exited my house, so it may have been falling from a greater height? – Sphere made no perceivable noise; location of contact with the ground was an open grass field. I went to the spot the sphere had hit the ground and found no sign of disturbance in any way. I would be most interested to know if this type event has ever been reported or explained.

Hi, I'm very interested in electronics, and especially finding analogies for electric components and behaviour into being physical things that we can see and touch..(plumbing is awesome) So when I saw the capacitor water analogy my head exploded cause it was the exact same thing I've been dreaming up before I saw the pictures (only mine was square shaped ;)) However, I've also pondered about a possible improvement that can show the phaseshifting behaviour of caps; Imagine instead of having one rubber membrane, have two, and between them there's a compressable substance, say air or something. This means that when you run AC through it, there's going to be a delay(the air compresses) before the electrons are being pushed out the other end, thus introducing a phaseshift on the wave, get it? :) I'd love to hear your comments on this. Now I shall keep reading I've just started to understand the actual difference on AC and DC, after reading 'the speed of electricity'

I've been trying to research on my own what was going on with me & it just may be what you talked about in your article "Mother & Daughter in Mass. Detect Signals Through Walls." I don't "hear" the signals, but I "feel" them like waves in my brain (nowhere else). I feel them when TVs/computers are 1st turned on (but then I get "used" to it) & certain radio stations as long as I don't turn the station (when I turn it, it instantly goes away). I feel when my neighbors/strangers turn on their TVs, whether in a house or apartment or walking, riding by & I can definitely sense it in the same house even when I'm in another room or another part of a house (upstairs, basement, etc.) I even feel like a huge TV has been turned on sometimes when I'm driving on long trips & I don't even see a home, building, etc., just open space. Signals on antennae TVs get clearer when I touch it, but unlike your subject, it doesn't make me sick nor does my daughter show any signs of that happening to her. I grew up in west Alabama/Cleveland, OH, and I don't think I was near any facility like the one mentioned in the article. Are those plasma coil or sphere things in TVs, computers, radios? I'm seeking more answers than anything--thanks.

I understood the transistor action(p.d. between base and emitter acts like a gate and voltage applied to collector acts like a suction which sucks-up all electrons) but now have a few doubts about the "Common" Emitter and "Common" Base. What do you mean by "grounding" or connecting to a common terminal? How does one common terminal control the current between two regions? What is the main difference between the "Common" emitter and "Common" Base(in both the configurations base-emitter is forward biased and collector-base is reverse biased)? HELP!!!!!!!!!!!!!!!!!!!!

I am very pleased to have found your site. I was looking for directions to perform Newton's experiment supposedly using two prisms to recombine dispersed light back to white light. In my effects the two prisms seem to prove the exact opposite of what the experiment was meant to show. My preliminary effects using a magnifying glass worked better. I intend to make a number of real set ups that actually demonstrate the principle that that white light is made up of the spectrum colored light that actually works. I will photograph these and place them on a new page on my web site. I also enjoyed your discussion about your philosophy on science. I think that science is magical, fun, and beautiful. I have created science toys and kits focussed more on the discovery and the art of science. My goal is to stimulate a sense of joy and adventure in science using things that marvel, bring out the asking of questions, and the impulse to say "let me try that" and I wonder if.."

I think that the sundog destruction by the SDO rocket launch is the same has sundog distortions by electric fields in thunderclouds. Robert Greenler and Les Cowley found a new halo created by it and determined that the arc of light was formed by gyrating crystals. ( http://science.nasa.gov/science-news/science-at-nasa/2011/11feb_sundogmystery/ ) The electric fields also disorientating ice crystals on your website are likely causing the same arcs of light as this.

I am a small UK businessman with very limited knowledge of electronics and have a problem with a pcb and am worried I may be ripped off, If anyone can offer help I would be very appreciable. I have a conveyor roller labelling machine, there are three principal components; the main body roller conveyor, labelling head and a smaller wrap around conveyor. The conveyor components are each controlled by an individual subject board. One of these boards has ceased to work. Having compared the resistance across the primary coil with remaining working board, It is suspected that the fault lies with the transformer The boards are Durag DS152 Am50-10, the machine was purchased in 1995 and am I informed discontinued in 2007. What would you suggest in this situation. Is the board repairable? Clive Perry

Hi Bill, I agree somewhat with the last entry. Things are a lot simpler than we can imagine, but has nothing to do with religion. We have perfected and built a 48KW 380 volt "self energising" electricity generator. We ask for nothing more than for you or anybody else to test it in any way you wish, for as long as you wish, without asking "how" it works. All I can tell the World ......... It works.

I just watched the video on how to stop traffic jams, and I must say it's probably the dumbest idea I've heard of. Traffic jams are caused by bottlenecking, where you have more flow down same path causing back pressure. your 'leave a large space in front of you' theory is flawed in that not everyone can do it because there is simply not enough space on the roads. By slowing down you're only causing a lower net speed through traffic, I guess if you have nowhere to go fast it may work for you, but on the other hand I guess I would be glad to jump in that space in front of you and get around your slow @$$.

i really liked the video on the generation of electricity using magnets copper and card board... i wasnt sure if it was oscillating or not...i am embarking on taking a fan motor out of a fan to make an oscillating tibetan prayer wheel lamp that will project images on the wall. i am fairly sure this is a simple task for you to accomplish...was curious if you are planning to a how to video in the near future for something of that nature...how to use the fan motor from a fan to oscillate a lamp ...there are other methods involving using the heat from a bulb to generate the movement of the lamp i also searched the internet pretty thoroughly, as to where i could purchase these motors or bases my self but i havent had any luck there has got to be a better way ??? have searched also on how to make the gears to turn the motor im sure it is so simple a kid could do it...im just not looking in the right place maybe just maybe you are the right one!

I am a tour bus driver and consider myself to be a good driver. Leaving a distance in front of me is something I practice on the highway, counting - one thousand one, one thousand two - etc... and while I have never noticed that it improved traffic, I did feel safer especially when it came to a sudden stop. My comment wants to address city driving and especially stopping and starting at a traffic light. I always make sure that I see the road in the space between the wheels of the car or truck in front of me. I have discovered that when the light turns green and that car starts to move, I can move in unison and observed that without fail the cars that followed me stayed at a stand still for several more seconds because they were stopped too close to me and did not feel safe moving right away. I, not being quite able to do the calculations necessary to prove my theory, would love to know if the distance left between stopped cars would not improve the speed with which left turning cars could clear the turn lane thereby eliminating the temptation to keep turning even though the light or arrow no longer gives them the right of way.

I made the Ultra simple Electric Generator and it worked as well, but I need urgent help with something. The magnets I placed inside the box keep slipping off when I spin the nail, and I have tried everything to fix them, but nothing works. I taped them together and tried other things, but they still slip off. I don't know what to do,because when they slip off and don't spin the bulb doesn't light. This is for a science fair project which is due soon and I need your help urgently. Can you please tell me what to do, so they don't slip off and spin like yours do. Please write back asap. Thank You Very Much

Bill, enjoyed your article on how transistors really work. It was both informative and entertaining. One suggestion though. Adding the sentence, "For example in a radio, transistors act as amplifiers for the electric signal when radio waves are converted to electrical impulses.", would have been the cherry on top the cake! Good job! Tommy

A new book provides an explanation that Ball Lightning is an Electron Spiral Toroid Spheromak, a new discovery. This book also reports the first known observation of Ball Lightning while it is forming. The book describes clean energy technology that will be possible based on this explanation. This has the potential to replace gasoline with clean fuel that has 100,000 times more energy per kilogram than gasoline. Experiments and analysis supporting the explanation are described that explain why it is self-stable in atmosphere and needs no external magnetic field for containment. Included as appendices are confirming technical papers co-authored by consulting scientists. The book also describes the breakthrough achieved in 2010 to enable scale up of the results and to enable applications. This book is written for engineers and others interested in finding clean energy alternatives to energy sources in use today. You can link to a website that further describes the book at Http://www.lulu.com/content/10117874 Please note that all proceeds from sales of the book will be applied to further the development of the technology and its clean energy applications.

My 18 year old son was studying for his exams and we were discussing lasers and could not between us understand how they were coherent, collimated and monochromatic even after reading the text books (and wikipedia etc). Your article on lasers explained it - why don't the text books explain this rather than trying to make it simple (and not understandable because its wrong)? Thanks for this - you should compile your work into a text book that goes alongside the syllabuses (of all countries), excellent.

Okay, before I begin asking questions. I need to establish my stance. I have some questions, some really simple questions that can be answered easily by Bill or any other science enthusiast/hobbyist/pro/student. I am a fine arts guy, studying Literature, aspiring to be a businessman, and has a lot of interest in science projects(even though I m weak in it). To me there is a very thin line between Art, Science, Business, and Literature, and it is pretty blur. Question : How do I know what power is being generated from a certain rotating object? For example, a horse is galloping on a giant treadmill, which gives us a rotating rod/pipe thing that can be used to generate electricity. How do I know how much power is it giving me? If not a horse then a man turning a wheel with a bicycle-like pedal. However, the turning is consistant. Bill made the 'Ultra-Simple Generator'(it was incredibly impressive). I want to know, is it possible to find out how much power was being generated and at what rate? Thanks, Maseeh P.S.: I am a lay man! I humbly request that the answers be as simple as possible.

Hello, I have spent a long time and much time searching to find out the way to keep a bobbin current flowing one way and why it seems to change. At close to 60 years old I thought this one would be easy. Guess at my age I should have known better then that! I am still not sure but out of at least thousands of searches this one gives me the best clue yet. I have not found anything close to this one. I wonder if I could ever talk to you in person? I feel like you are the only one that has a handle on this and it really seems to make sense to me? This has slowed down a project for to long now! If we may talk I bet I could solve it. This sure gives me a different direction to look toward! One way or the other thank you Bill for taking the time to post this! Thanks Again, Stewart

Hello, I find reading YouTube comments on my own single video difficult, so I choose not to give others that hassle. So, I spent a good 10 minutes finding your email, and came across the comment page, then the guestbook. Anyway, what I'm wanting to know is about your abrasion holograms. How have you gotten things to appear above the plastic? Such as, the tetrahedron and your second cube in your YouTube video. Am I right to assume it's scratching it from the apposite side? Perhaps I worded it wrong, so I'll use some poor ASCII art to demonstrate. To make it appear below, as normal, you'd scratch like: ____ / \ / \ But to make it appear above, it'd be more like: \ / \____/ I came to this conclusion when you demonstrated that the upside-down cube appears to be a "hollow-room-cube"(not quoting you, using my poor choice of words) that is above the plastic. Thanks, Alex

So now what? I knew that there had to be others like me and now that I know this is true - what now? There's no resources or direction - no way to harness or direct, at least I don't know how. What religion encompasses this? Supports or teaches about it? I know I have a gift and that it IS huge - it overwhelms me and I tend to shy away instead of embrace it because I feel like my plate is already full with what I DO know. But this ability to effect electronics, lights, attitudes, dream precognition - why? what for? What is the purpose? Why me? What am I suppose to do with it? I don't want to hear voices or see things - I just want to know what I am dealing with ... it seems SO many are, yet there are not many answers or directions. This site was the one common avenue found by most of its readers - seeking others out like themselves. I wonder if we all got together and got REALLY angry if we could power or black-out a town completely, lol.

Bill, I read your article "Tesla's Big Mistake" with great interest, whilst looking into the basis for the G-line. You might like to note that Glen Elmore of Corridor Systems Inc. in his paper, Introduction to the Propagating Wave on a Single Conductor (see http://www.corridor.biz/FullArticle.pdf ) explains Goubau was mistaken in believing a dielectric coating was necessary to prevent the TM surface wave from breaking away from the single conductor (i.e. radiating energy). I would be most interested if you can find a flaw in his explanation or alternatively point me to where someone has done so. Regards, Phil (G3MGQ)

Hi Bill, Truly an excellent site! I wish I had found it sooner. So...according to my research, humankind is about to get annihilated via planetary lightning. Most likely from Jupiter or Saturn. Ever read Pliny? Anyways, I'm working on an ark of sorts, though, given the time left, I'm not sure I'll have it done soon enough. I could use an open minded engineer like yourself, as my engineering skills are not all that good. reference - Bell Island boom, Pliny, recent Jupiter changes (lost the southern belt, will lose the other soon and then light up per my theories)Jupiter/Saturn radio emissions. Thirteen months left, perhaps more. Email me if you want to know more. ps. I'm not religious, just think life in the universe is rare, feel that since I know whats up, I have to try and do something.

For some reason electronic stuff breaks around me. I often joke that I need to stay in shape as a pacemaker would be gone in days.
Yesterday my Wifes brand new 20 minute old phone stopped working after I touched it. My Computer went on the fritz, then my Ps3 broke down for the 2nd time in a month. Finally I went to use my good bose headphones and they were now not working.
My Brother will not let me use his stuff because of things like this. I would love to know why this happens!

Sams is worse with their huge metal shelving everywhere. I keep thinking there must be something useful to use all of this electricity for. If they ever do studies in my area let me know. (mountain)

I have read through some of the contents in your "Physic Misconception" section, and I just want to say that although I don't have the time at the moment to research on each and every content myself and confirm what you suggested, but I found the contents on this site very valuable. If you decided to have your website contents confirmed rigorously by multiple professional institutions, universities, publisher of scientific articles, and publish it as a book, we the science geek (or at least myself) would then have a science misconception bible to hold on to, which would be awesome and I will carry it with me wherever I go. Thanks again. [ Most of this collection comes right out of undergrad physics texts. I thought this was obvious? It's just very basic equations translated into prose. Also most of it was discussed over years on the university physics forum PHYS-L. It's utterly conventional. What's shocking is that the general public doesn't already know this info. Another big problem is that some K-12 grade school authors copy each other (and constantly accumulate errors,) rather than basing their books on solid references and writing from scratch with no copying of other authors' mistakes. PS, if you think you've found an actual physics error anywhere in my site, PLEASE PLEASE email me and point it out. The PHYS-L crew got most of them at the start, but you might find one. Beware though, since what looks like a mistake is usually a piece of correct info that contradicts a widespread unexamined misconception -billb]

I am an RC Hobbyist. I recently built a gyro plane with no airfoils on the rotors. And it flys to the dismay of heli pilots. This would tend to support the Neutonian airfoil theory preference. Can a flat bottom airfoil lift at zero attack? If so, can this be attributed to the downward flow of air from the top of the airfoil coming off the back of the trailing edge? And how does a bumble bee or a Frisbee fly?

I love this site and the information you provide! I've spent many hours thinking about these things that you've shared and I think I understand it all except for what exactly electrical energy is. (I wanted to mail a question but that page was disabled).
If the flow of charge through wire is only needed to create the fields through which electrical energy will flow, where does the electrical energy come from? If I understand correctly, a battery is just a thing that stores an imbalance of charge so that you can cause charge to flow through a circuit. Since the charge is not the energy, and the battery is just a way to cause charge to flow so that you can create fields for the energy to flow through, what is the energy and where does it come from?
Thanks again for hosting such great information and dispelling the myths! (Sorry for previous posting in wrong place)

Hello, I am a happy reader of your pages. Thank you, and thank you again!
I'd like to know if I am understanding correctly that in the example,
where a copper rod is bent in a ring and spliced into it are the battery
and a light bulb, the light bulb is heated and lit up by two forces
simultaneously: [Exhibit A] the friction from the Coulombs and the
[Exhibit B] the friction resulting from the electrical energy that forces
itself through the flow of Coulombs (which may or may not move against the
[ Only flowing charges experience friction.
Flowing energy can be absorbed, but it doesn't "rub against" matter or
create frictional effects. EM field energy
flowing into charges will drive them forward even against a retarding
force caused by friction. The flux of energy is keeping the charges from
being decelerated and halted, otherwise the friction would bring things
to a stop. The forced motion of the charges through
the resistive material is causing a type of frictional heating. -billb]
This leads leads me wondering which of the forces create greater friction
on their own and if there are instances where only one of the frictional
forces are present and not the other.
Hi, I quite enjoyed your article on right-angle circuitry. I could answer some of the questions you left unanswered -- but I'm pretty sure you could too, and I liked how you were explicit about what you hadn't worked out -- yet assumed you could if you put in the effort. A good approach, and a good example!
Transformers are fun stuff - and a good chance to use vector calculus, line integrals, etc. But as you ably demonstrate, you can work out a lot with simple qualitative reasoning.
Re: fringe science... the problem I have with fringe science is that of people abandoning scientific principles in favor of belief. You're sort of pointing to the opposite problem -- of scientists abandoning scientific principle in favor of their scientific beliefs!
Really, hyper-skepticism is a great thing. But you must NOT BE SELECTIVE about where you apply it. Apply it to the "conventional wisdom" as well as that new idea. And apply it to your own process of reasoning and skepticism.
Too often that has been overlooked. Ovonincs is a great example. I read about it as a kid back in the 60's. I think he hurt himself a bit with failing to be skeptical about the market implications -- though he made up for it to a degree with enough persistence to find some relevant niches.
But the people scoffing at it were really being brain-dead. OK, the idea is different. Amorphous semiconductors? Really? There's a big difference between your current knowledge not containing an explanation, vs your current knowledge containing an explanation of why not!
I think fractal antennas fit in here somehow. Maybe you've written about them and I missed it. I don't know their history, but they certainly go against the conventional wisdom when I was a kid. I wonder how the guy who first proposed them was received?
But now, you find them in a lot of places -- like inside cell phones. I have a daughter who takes things apart. No, not my little one, my 21-year-old -- an industrial design student. Fun stuff -- like her old cell phone. Seeing a little flexible circuit with copper squares of progressively smaller sizes brought a smile to my face.
I don't claim to really understand them. Hell, there are things about a simple dipole I don't really understand. But it's such a surprising, verifiable, and mathematically interesting idea...

Today I happened to run across this document ("http://www.free-energy-info.co.uk/Chapter5.pdf"), and it contains reference to, and apparent quotes from, a 1923 patent (253,765? confused, because the text in the article refers to another of his patents 843,550) for "Electrical Power Accumulators" that might be of interest - I believe it embodies some of what you have described, with a reported input of 500 watts at 500,000Hz producing what I believe computes to be an output of 3000 watts (50count*60watt bulbs).

Thanks for the interesting list of misconceptions. One thing struck me about the laser description, though: most helium-neon lasers do lase simultaneously on several longitudinal cavity modes. (Only a physically short laser would have mode spacing so wide that only a single mode would fit within the neon gain curve.) There's a description here: http://www.laserfaq.org/sam/laserhen.htm#hentoo1 Showing students the mode structure of gas lasers with a scanning Fabry-Perot interferometer might be interesting for a middle- or high-school class. One can see the lasing modes drift through the gain curve as the laser warms up and expands slightly.

Would like to use the IR goggles for a self-guided tour of the Aquarium to let participants experience "remote sensing" for themselves. [Yes, check out the article links to telescope safety sites. Daylight is dangerous if you stare unblinking at the sun. If pupils are dilated, and visible light is removed, and only IR sunlight is passed through filters, it still takes minutes of staring at the sun in order to cause damage. -billb]

My theory Violated Your Crackpot... I imagined the energy 'nullifying area' as small sphere of radius 'r' and with the help of Wave Mechanics,I assumed-Amplitude=k/r,where K=constant. w(angular freqency)=c/r,where c=speed of light. As the radius of imagined spher decreases,frequency also decreases,i.e,badly effects the Sucking of light frequency..And the Amplitude too..Hence there cant be any increase of he size of imagined sphere..Which crossed your Crackpot.If r=0.1U(micro)m creates a fine layer around an atom,i.e as interference medium ,whose density is far greater than Air.Hence light or E.M bends towards it..Hence it receives a finite Energy..But if the Frequency is maintained or needed of 1Mhzs..needs of radius of sphere almost r=47m..yes amplidude nearer it decreases,but the remaining part is traversed in this thick medium.....correct me ...If iam wrong...

I discovered a cheap and simple way to get microwave oven "plasma balls" going. Simply use 1-3 strands of fine steel wool. As soon as the oven turns on, the steel jumps into skittering orange balls of magnetite, but they spawn a plasma at the same time. This would probably work with a very small quantity. I surmise that the carbon in the steel is sufficient to create the plasma-- or perhaps iron vapor.

IN A SIMPLE CIRCUIT, WHERE DOES THE ENERGY FLOW? I am confused about what what appears to be contradictory information in several articles. What causes the resistor (light bulb) to heat up and glow in the circuit? Is it the friction of the current flowing through the resistor or is it the flow of the energy into the resistor?[The answer is yes! :) Well, "current" doesn't flow, only charges flow. Analogy first. With ropes and pulleys, the rope moves slowly but the mechanical energy propagates along the ropes almost instantly ...so whenever you heat your thumb upon the moving rope, ask yourself whether the heat caused by absorption of mechanical energy, or is it really caused by rope friction? Of course it's both. By rubbing against the rope you absorb energy from the whole system and slow it down. By rubbing the rope you also cause frictional heating. With circuits it's similar: flowing charges can create "frictional" heat by rubbing inside a resistor. But whenever heat is created, electrical energy must flow into that resistor in order to flow out again as thermal energy. Friction slows down the charge flow, and if the flow speed is to be kept constant, energy must be injected elsewhere at the same time. The charges form a flywheel, where the resistor slows down the wheel, and the battery speeds it back up again. Ropes, and circuits, and hydraulics all work this same way: two things are flowing, a rapid propagation of wave-energy, and a slow circular motion of physical medium (charged particles, or rope molecules, or water molecules.) -billb]

the explanation of BJT operation is incorrect, yes it is voltage controlled, but the width of emitter base depletion is irrelevant for the magnitude of the collector current. [Wrong. Go and review basic diode physics. The changing Vbe potential-barrier is determined by the amount of uncancelled dopant ions in the depletion layer, which is determined by the layer width ...and Ic is determined by the height of that barrier. A diode junction is a "variable electret," and when mobile charges are removed from any region, the charges of the fixed ions are no longer cancelled, hence the barrier height increases. -billb] simple proof is measuring the same device in forward and inverse (emitter collector reversed), the collector current will be almost equal whereas the depletion zone willbe quite different due to substantially lower doping level in the collector.
[No, when explaning how transistors react to changing signals, we aren't allowed to suddenly swap in a different junction (or to vary the doping, the temperature, mobility, etc.) Those parameters remain fixed during normal operation, so they have no place in this explanation. Of course if we don't know the temperature, mobility, etc., we cannot calculate any actual Ic values. Calculation has no place here. Perhaps you see Babylonian explanations as wrong, since they give no numerical predictions? Don't lose sight of the fact that most explanations seek a numerical answer, and so they're forced to focus on the potential barrier which allows us to calculate Ib and Ic. My goal is to explain transistors to my grandmother, so it's routed away from equations and from concepts such as "potential" and "barrier height." Instead I focus on the origin of that potential barrier: a variable layer of charged insulator which stands in the way of Collector Current. Then I don't even mention barrier height (which is the whole point of Babylonian: focus on visual/intuitive, discard numbers, insert pictures and prose.) Watch as the depletion layer widens, and any slower charge carriers wandering into that region are repelled back out. At a certain width, no carriers make it through. -billb]

Hello, I have an odd problem and I wonder if anyone can explain it. I live in an old house on a Greek island high up on a hill. I have a small old fashioned deep bath. When it is full (and I am in it) I can feel a slight electrical charge coming from the plughole. I have made sure everything is switched off in adjacent rooms (I worried that there was a loose wire under the house or something) and it is still there. It is enough to cause a slightly unpleasant pinpricking sensation on the skin. It appears to be something to do with the strength of the suction from the plug but I have absolutely no understanding of such things. It worries me a bit - plumbing and electricity in these parts is a bit haphazard but I am also curious as to whether it is to do with the rock we are sitting on or something -there is one hell of a pull on the water going down the drain! Anyone got any thoughts?

I have a great free website that teaches students about lab safety. The National Institutes of Health, Division of Occupational Health and Safety (DOHS) developed a laboratory safety training program called STAR-LITE (Safe Techniques Advance Research . Laboratory Interactive Training Environment). STAR-LITE is an interactive computer-based laboratory safety training program for high school students and undergraduate university students. The program incorporates common features seen in today.s video games, i.e., selection of an individualized character; first-person views; and three-dimensional graphics. The method of instruction integrates visualization of consequences, e.g., slips/trips/falls, inhalation of chemical hazards, spills of biohazardous liquids, development of critical-thinking proficiencies, and application of problem-solving skills. STAR-LITE is available to download and use for free at www.starlite.nih.gov. I think that this free and dynamic program would be of interest to science teachers.

I HAVE A QUESTION !!! Excellent attempt to kill some monstrous misconceptions. I'm "kind of" electronics engineer that's burried deep into magnetic field research. It's mostly due to firm religious believes that i believe things work a lot simpler than we think. My education, although not reached the highest levels was enough to find out that most of us were 'poisoned' by either stupid or carefully crafted science "facts" (who knows how we got at this point). To get to the point, the word 'imbalance' you use to explain "static" raises some questions at least in my head. The followings are actually one question. In what sense opposite charges 'Cancel each other out' and later 'get separated' again? Is it the distance between protons and electrons what makes the difference between charged and uncharged? If an electron is close enough to a proton (an atoms core with a redundant proton) it becomes neutral mass? If you could spare a moment, i would like to hear your point of view or suggest a link. Thanks ...

Bill, I think this is pretty great stuff. I guess I bring aggressiveness from being young and from the east coast to the roads, and have gotten myself stuck, including when I was driving buses, but now realize that a little courtesy could go a long way. I was already learning to be laid back and understand people will do things and not to respond but not react. But now I realize, especially for a commercial driver, a little more patience will pay off. I highly recommend you try to consult for bus/ truck companies and insurance co's. Even in this economy you might find you can get a presentation together and make some bank, if you're not doing this already.

Is there a suppression during a time of need, this makes no sense for our future is at risk!!! I believe the coal companies in my country, Australia mainly control what we see and hear because we export so much coal. There are free energy technologies and Permanent magnetic motors, if each house had a permanent magnetic motor to power the home and we drove more responsive electric cars. There would be hell of allot less greenhouse gases being emitted. If you can understand this next bit then welldone if you cant then think harder! DRAW this, 5 evenly spread lines coming out from a center point each tipped with south poled magnets as the north side of that magnet first comes out from the center then have 4 evenly spread SHAPELY curved double poled magnets(north-south) on the outer. Using the right stretched,half diamond cured inwards shape outer double poled magnets and materials this pattern in general could be redefined to make MANY different types of magnetic motors.Can you think of your own? i have dozens in my head and could have been a billionaire but i just want a better future .its so easy!simple ideas are usually the best ideas! Using the right combination of old and new technology with enough static energy to overcome part of the laws of diminishing returns THIS WILL power something usable, such as a house and much more If you have drawn it right you will have one inner south poled magnet in the center of one of the double-poled outer magnets while two of the inner south poled magnets are attracting the other two are being repelled this then forces the one that is in the center to repelle at its thickest part of repelling. just something i come up with when i was i teenager drawing doodles on a bit of papper, then my brain incorporated magnets and this is what i came up with.So SIMPLE. this has been recorded in history through the internet as my idea, i bloged this to another site and i can imagine the greed of people trying to write this off as their own idea. did this shut down the American patern company for a day! can you help us to live a better life from this information. To have energy use at a low minimum to your environment , work, shopping and social activities. meaning little distance between. Placing a wind farm in a windy area, solar in a sunny area, a tidal generator were water shifts more and a hydro plant were there is a river ect ect and for it to be transformed in to a energy solution still viable with future growth. we should work with rural and urban communities to apply future modeling to provide strategies, tools and principles that help plan and invest in the future by maintaining and sustaining ecosystems, biodiversity and long-term growth.$br$$br$. I am Australian Aboriginal and Australia is the biggest coal exporter, that is why i believe we will go the way of the Dinosaurs if we dont act. the 21st century will have a thousand times more technological advances, i dont think anyone could fully understand this.

The microwave melting of glass & igneous rocks set me to wonder: How is it at melting sand ? More precisely, how little melt, perhaps seeded, is needed to 'fix' a casting box of sand to a brittle foam... There won't be much strength in this cousin to fulgurites, but, like their inverse, 99% air aerogels, they could minimally immobilise the volume...

This concerns a VDG. Is it necessary to cut a hole in the sphere so that the charge belt is inside the top capacitor? I see some hobbyists doing this and I don't understand why that would be necessary since the combs carry the charge thru a wire that is attached to the sphere.

Thanks so much for all your help! i have one more question though. I'm having a little trouble implementing the schematic you provided (http://amasci.com/maglev/magschem.gif) so my solenoid is turning on, but my hall effect sensor isn't switching the circuit like it's supposed to. I'm sorry if this is a stupid idea, but i was under the impression that When i put a magnet near the hall effect sensor, it would switch the polarity of the solenoid. but for some reason, that isn't happening. I am using two 9 volt batteries, but other than that, all the components you recommended using.... i'm using. i've attached a picture of the schematic you provided, but i've circled two parts of the schematic that i do not understand. I'm talking about the hollowed out arrow coming off teh hall effect sensor and the hollowed out arrow coming off the solenoid. Where do these connect to the rest of the circuit? as of now, i have just been connecting one of them to the positive wire of one of my 9v batteries, and i have been connecting the other to the negative wire of my other 9v battery. Thanks For all of your time... Sharvil

Great site. It really highlights all that I've bee taught and just how wrong it is. I'm currently in the photovoltaics industry working as a project manager. I want to understand exactly how it all works. What I'm learning is that I understand the photovoltaic effect, but the design and implementation of photovoltaics becomes complicated from the point the PV effect has occurred onward. In other words, what happens in the module is simple, what happens from there through the dc conductors, fuses, breakers, disconnects inverters and panels is more complex. This is amazing, because this is all electricity that we understand. Great site and I have a lot of reading to do.

Hey guys, ever sense I was 3, I have loved science and technology. I could turn on and play a PS2 when I was 2 so I have alwase thought I was just maby gifted at this kind of stuff. But now that I'm 15, I am realizing that I may be verry gifted. Whenever I get a flu shot, I am ammune to electricity for about two days, I can't dim lightbulbs or blow computers out but I can touch a live wier, broken iPods and some remotes and make them function properly again. I was wondering if anyone else could do these things. It seems to me that also I can somehow turn things on by simply touching them or thinking about it. I have had my iPod randomly go off sometimes playing one of my favorite songs when just moments ago I took it out of my pocket to go to bed. There is no alarm set eather. I also noticed recently that I feel like there is a verry dim but noticable electric current running through mostly my feet but sometimes my head arm and hand. I just thought I'd put this out there and maybe someone else has the same thing happen to them. Thanks for reading.

Your instructions for the maglev train are incredible! I love the way you give the reader places where they can improvise. I just had a quick question about your instructions. I plan on building a track that is 16 or 17 feet long, that will have two lines of magnets. These two rows of magnets are responsabile for the levitation of my "train". I got a little confused when you were explaining how we are supposed to make/buy multiple solenoids along with multiple circuits following the schematic you provided. What confused me is why u reccomend making MULTIPLE solenoids and circuits. Couldn't i just make one solenoid along with one circuit/hall sensor that is attached to my "train". This one solenoid and one circuit/hall sensor would line up with a single row of magnets (this row of magnets has alternating sides facing up...ex: south,north,south,north) Wouldn't the hall sensor adjust the polarity of the tip of the solenoid and push the car forward? I don't have a ton of time to experiment or a very large budget, so i was hoping you could clarify Thanks so Much! Sharvil

Why not charge $100 to deal with a specific question? This would eliminate your inbox backlog and filter out time-wasters. Give the revenue to charity or use it to subsidize the generation of more great website content. All previous answers visible to everyone to avoid repeats, or for $100 you can email a lazy/rich asker a link to a previously answered question. Use LivePerson or JustAnswer or something like that, or even easier just tell people to put thier question in the comment section of a PayPal payment directly to your email address. If you ever get a question too time consuming for $100, just quickly bounce the payment and indicate the minimum price for that question and leave it up to the questioner if it would be worth it to him to repose. Also show these bounced questions publicly. Eventually have a self moderated board where people can contribute to questions they'd like to see answered. The wisdom (or want of wisdom?) of the crowds becomes the gatekeeper. You never have to pick which questions to answer.

In your 1989 article titled "New Ideas in Science" you complained about the state of the science of geology. I think you are absolutely correct. But it isn't just a problem with the petroleum industry. The problem runs all the way to the foundations of the Geophysical sciences.
Sir Charles Lyell did a good job of heading off the creationists. But he
also shut the door on any consideration of sudden,violent, catastrophic,
events as a driving force in the geomorphology of the surface of this
The likelihood the observations of an amateur will be taken seriously by
the academic community is inversely proportional to the significance of
those observations. So that a really big idea that changes anything has
about as much chance of being heard as a mouse breaking wind in a
hurricane. And, paradoxically, the importance of communicating those
observations properly is directly proportional to their significance. So
it's a kind of Cassandra's curse for the 21st century.
Let me tell you about a different kind of impact event.
Evidence for an extraterrestrial impact 12,900 years
ago that contributed to the megafaunal extinctions
and the Younger Dryas cooling
Before I was aware of the R.B. Firestone paper, and before I was more than
marginally aware of the megafaunal extinctions at the end of the last ice
age, I was looking at the blast effected materials of an explosive event
more violent than anything I could imagine; not even with military
Impact melt is often mistaken as volcanic tuff. And, when viewed form the
surface, they can be so visually similar that only detailed chemical
analysis can tell them apart. But no matter where you find them, and no
matter the source of heat, and pressure, that melted, and moved them,
ignimbrites are always formed in a violent explosive event. And as a blast
effected material they are always a direct signature of the explosive,
fluid, motions of their formation, and emplacement; no proxy required.
The sudden, unimaginably violent events of their formation can be
understood to an amazing, and extraordinary, level of detail if one simply
studies how they moved as blast effected materials moved during
emplacement. So the only questions I am asking here are concerned with are
simply: How did it move, and flow? We need only to get enough altitude to
see the actual patterns of movement, and flow, to determine the exact
movements, and true points of origin, of a sheet of surface ignimbrites.
So the science of Fluid Mechanics has the trump card. And it doesn't get
any easier than when the materials are exposed, in pristine condition, on
I would have thought that the geology of the north American continent was
all very well studied. But when you start looking for any detailed
research on emplacement of the pristine surface ignimbrites in north,
central Mexico, and west Texas, and the exact nature of the explosive
events they were formed in. You quickly find that, while there are quite a
few untested theories, detailed studies of it's origins, and fluid motions
during emplacement, haven't been done. But by understanding the motions,
and fluid dynamics of the ignimbrites, and other blast effected materials
we can come to a true understanding of the nature of the explosive events
they were formed in. You can look at a flow, and easily see which
direction it was moving at any particular point. And, in a hi-resolution
satellite image, the motions of the ignimbrites in central Mexico, and
those in west Texas, are as easy to read as the patterns of movement, and
flow, in splashes of mud, or spilled paint.
There has been some mapping of ignimbrites in the Chihuahua City area, and
on northward for about 100 km, or so, in spots along the Chihuahua - El
Paso highway. It's taken years to get just that little bit done. But there
is more than 40,000 square kilometers of pristine, random-colliding rivers
of fast flowing ignimbrites in central Mexico, and up into west Texas that
look like they just cooled yesterday. Waiting a lifetime for those
Geologists on the ground was not an option. And, in frustration because I
couldn't get my hands on any decent research papers on the subject, I set
out to work out the patterns of movement, and flow, for myself to get a
better understanding of the explosive event they formed in.
The movements of an unconstrained fluid are defined by the forces moving
it. And for our purposes we'll need to refine that profoundly simple
observation a little more and say that there are two fundamental forces to
consider; gravity, and pressure.
Take a droplet of paint, and put it on a level surface. Then blow it
around with a straw. That's a pressure driven fluid. It's characteristic
patterns of movement, and flow, are the result of the motive force being
behind the flow, and pushing it. It piles up at the low pressure areas on
the periphery where the pressure is no longer strong enough to move it.
Next, tip the surface a bit and let the paint flow downhill. That'll be a
gravity attracted fluid. Its patterns of movement, and flow, are
consistent with the motive force being in front of the flow, and pulling
it down hill. It doesn't work on level ground.
The lines of flow in an unconstrained, and driven fluid will always be
away from the driving force. Even if that fluid is melted stone being
driven up hill. And when those lines of flow are frozen into a river of
melted stone they become a permanent, reliable record of the nature of the
forces that melted, and moved it.
Cover a surface with about an inch of wet, slightly sticky, grainy, mud
the consistency of thin, wet, concrete. Hit it with short bursts of
compressed air coming down from above to simulate the patterns of
movement, and flow, in a pressure driven flow of blast melted ignimbrites.
A fun variation if you want you involve the children is to use runny
oatmeal spread out on a cookie sheet. If you have the kids surround the
Cookie sheet, and blow the oatmeal around with short, random, puffs of air
thru a straw. You get the same flow patterns. But the kids taught me one
should be vigilant, and use caution with this version of the experiment
due to the danger of the experiment escalating into a food fight. If you
look away at the wrong time you could become the first casualty. It was a
good learning experience for all though. The kids learned what the flow
patterns of a pressure driven fluid look like. And I've learned that it's
difficult to do good, objective, scientific, observation with oatmeal in
You can mock up a classic science fair scale model of a volcano if you
want to simulate the flows of a gravity attracted density current down
If it takes months, or years, to map a few miles along a highway from the
ground it's time to bring the work into the twenty first century and use
the satellites our tax money paid for, and do it from space, or it'll
never be finished. Thanks to NASA, LandSat, and Google, I can produce my
own image map of any given area on the continent in full spectrum color
with resolution down to about 1 meter per pixel. And computer memory is
the only constraint to size. I have a couple I've had printed
professionally that cover a whole wall. If you look at a specific location
anywhere in those flows, it is very easy to see which way it was flowing
at any given point. And backtrack it to its source location. A sheet of
clear plastic, and a handful of markers, and you have a large area,
hi-resolution flow map. Complete with little directional arrows.
There are gaping holes, and glaring discrepancies, in the data when it
comes to the actual movements from it's supposed source vents, and final
emplacement. There simply aren't enough vents. And you can't say it came
from one direction if it was flowing from the other. Those material
movements tell an extraordinary story, one that is far different than
anything we ever imagined.
In an explosive volcanic eruption we see both gravity, and pressure at
work as the material is ejected from the vent forcefully, only to be
attracted by gravity down, and away from the vent. And it rarely flows
very far. But we see something different going on in central Mexico, and
west Texas. There are tens of thousands of square kilometers of pristine
ignimbrites, with no visible signs of decomposition, at the very top of
the geologic column. And the patterns of movement, and flow are not
consistent with a volcanic eruption at all. All of the material movement
is pressure driven. There aren't enough volcanic vents to account for even
a fraction of all of the melted material. And, because of the scale of it
all, you don't see it until about twenty thousand feet. But when you spend
some time studying the movements of the blast effected materials in the
satellite images, you'll notice something that generations of Geologists
on the ground missed. The simple, observable, fact is that, contrary to
the old literature, the melt didn't come out of the ground at all. It was
the original surface terrain, blasted, and flash melted, by multiple
sources of heat, and pressure coming down from above. The material was
blown off its source locations by those same above ground sources of heat,
Any given fragment of ignimbrite, no matter the scale of the event it
formed in, was only in fluid state on the surface for a few violent
seconds at most. Even in a super eruption that goes on for days. So if two
flows of melted stone are representative of two separate events, even a
separation of only a few seconds, then one of them will be seen to be
over-topping the other, already solidified one. But if they were both
melted, and flowing at the same time, the interaction between the two will
be a fluid convergence. i.e. They will inter-finger. Or they will come
together like two rivers flowing into one.
Everywhere, in all of the tens of thousands of square kilometers of
random, colliding, flows of pristine surface ignimbrites you'll note that,
without exception, the patterns of movement in all of the material is
consistent with very fast, and sudden, motion like ejecta. And every
collision between flows is a fluid convergence. There is not one, single,
over-topping flow. The inescapable conclusion is that contrary to the old
literature, all of the pressure driven ignimbrites in the Chihuahuan
Desert were in rapid, fluid, motion at the very same time. All of that
tuff describes an intricate, almost infinite, dance of violent fluid
motions. And all of those turbulent, inter-flowing, motions describe the
very same moment.
Either that material is the geologically recent result of the largest
super eruption since primates first came down out of the trees. And most
of central Mexico is one giant, explosive, caldera that no one ever
noticed as such. And all of the missing vents will be found... someday.
(And never mind that the motions of the simultaneous, inter-flowing,
rivers of melted stone describe a sudden, virtually instantaneous,
event.) Or all of the melt is the result of the most violent ET encounter
in 65 million years. And it, and its ground effects, are different from
anything ever studied before.
Both are pretty extraordinary possibilities. The visual evidence is more
supportive of the latter though. Because, when viewed from high altitude,
it is profoundly obvious the heat and pressure to melt, and move, all that
material came from above. But, no matter what the source of the heat, and
pressure, the more than 40,000 sq km simultaneously, random-colliding, and
interflowing, mega-flood of blast-generated ignimbrites, at the very
pinnacle of the stratigraphic column describes a geologically recent
explosive event that was arguably the single most violent natural disaster
in all of human existence. Yet, with the exception of a few prospectors
looking for money rocks, it's almost completely unstudied.
Our impactors appear to have been a large, highly fragmented, and
loosely grouped, cluster of comet fragments, about 500 km wide, like a
giant, flying gravel pile. The thing would have looked like a sister to
the images of the fragmented comet Linear. It came in at very high
velocity, and low angle of approach from the southeast. And almost all of
the fragments exploded above ground like Tunguska. Except that, in Mexico,
only the very first of the fragments on the leading edge fell into cold
atmosphere. The rest fell into already super heated impact plasma, and
just added to the heat.
The primary impact zone is a 500 by 1300 km oval that covers most of north
central Mexico. And extends well up into west Texas, and New Mexico. The
other impact zone is a little smaller in the great lakes region. And it
extends from northern Minnesota, well up into Canada.
All of the available literature assumes the ignimbrites in the Chihuahuan
desert to be the result of ancient volcanism millions of years ago. But
there is no such thing as immortality. Even the rocks of the Earth crumble
to dust after a few million years of exposure to the elements. And those
tens of thousands of square kilometers of perfectly pristine,
simultaneously, random-colliding, and inter-flowing, rivers of blast
melted stone at the very pinnacle of the geologic column are most
certainly not thousands of times older than the stones in the monuments of
If an extraordinary hypothesis requires extraordinary proof all I can say
is look closely, and see for yourself. There is no visible trace of
exfoliation, or decomposition, in the flows at all. And except for some
sparse cacti, and sagebrush, growing on them, those flows of ignimbrites
are all in the very same condition as the day they first cooled. And
their motions are very easy to read.

Interesting article on the "air threads." Had me going for awhile until I figured out what they were. You're essentially seeing the effects of electron beams in a neutral plasma (air + CO2). To better understand the coherence of the beam, you might wish to investigate something called the "pinch effect." It is sometimes used in high energy physics to focus electron beams. Consider a lightning bolt, should not all those electrons be electrostatically repelling each other? How is a lightning bolt even possible? The neutral plasma (air) the electrons are traveling through creates a very high magnetic field that overrides the electric repulsion of the individual electrons and focuses them into a tube of lightning. I didn't see any references to deflecting your beams using permanant magnets, though I did see references to charged plate deflection. Perhaps I missed it. But it appears as though you are tinkering with small scale plasma-pinched electron beams. Regards, Jim Barzydlo

I know people can make them with a program, but I don't know how. There is a serious shortage of imagination and creativity in the Chinese school system. I think this would fascinate my students and inspire them. Can anyone help? Pleeeeeeaassssseeee. annaswikiaccount,a,gmail.com A thousand screaming Chinese kids also say "pleeeeeeeeeeaaaaaaaaasssssssseeeeeeee". Thank you so much. Anna.

Bill! Thanks for all if this excellent info on electricity, nay electrical phenomina... I've been fumbling around in the dark with confusing and conflicting street knowledge and academic knowledge on "electricity" for years. I've had so many questions and now finding your site the clouds have parted and I see the electromagnetism!

I liked your Electromagnetic Rant #2, it made me think of something: if you shake a charged stick, it will take more work than shaking the same stick uncharged because the "wake" of E field gradient that trails off the charged stick holds holding it back as you try to shake it. That wake of radiates out as an electromagnetic wave with the energy equal to the extra energy it took to shake the charged stick. Funny, huh? -John

Nice quotes section. But were you aware your Shakespeare quote is not by Shakespeare, but rather Neil Gaiman, specifically from "Sandman"? It has been misquoted often because he used a fictionalized version of Shakespeare as a character in some of his stories.

I discovered your analysis of traffic waves a few years ago and was very pleased that you had illustrated it so nicely. Following your line of thinking, I submit that automatic transmissions contribute to creating and maintaining traffic waves. Since cars with ATs don't slow down when the driver releases the accelerator, the driver must press the brake pedal and his brake lights go on. The driver behind reacts to the brake lights and does the same, and, voila, a traffic wave. Conversely, cars with manual transmissions do slow down when the accelerator is released, so less braking, fewer brake lights, no reason for the following car to brake, etc.

That was a great quote you wrote below. Totally agree. I am at this stage and finally things make sense! "Maybe the more skilled of electrical engineers and scientists gain their extreme expertise NOT through classroom learning. Instead they gain expertise in spite of classroom learning. Maybe the experts are experts because they have fought free of their classroom learning, while the rest of us are still living under the yoke of the electricity misconceptions we were taught. "

Thank you. I being a High school student was thought about transistors last year. Believe me all my doubts on this subject were never answered and was insulted by my lecturer and was always a joke because i asked my lecturer questions. I hate the education system in this Country 'which may have been a centre of education once' but today it is full of hungry (for money) people who have no thoughts no brains. Being a babylonic thinker one has no option except to hate this country.

Great article on traffic waves. I currently figured out the same on my daily commute. If I allow people to merge well ahead and I keep a constant 35-40mph then the traffic tends to move ahead of me before I reach it. I also notice a big difference in fuel consumption when I drive in this manner. I will normally get between 55-60mpg when I drive aggressively (I drive a small diesel) but when I drive more consistently and smoothly, allowing people to pull into the gap ahead of me I average 65-70mpg... so that saves me about Ł150 (approx $225) of fuel per year... Sweet. Keep up the good work! -John

Hi Bill, I browsed through your site several times now, and though I did not go deep into the stories' detail, I found it incredible that over several years both of us reached similar conclusions about the same phenomena, in completely different places.
I live in Israel and I see all the same scenarios.
Here, we too suffer of the "achieviness" syndrome - trying to get
everything we don't need just for the sake of some one else not having it.
I'm sure you see it all the time in the States :)
The difference is that while in the US size means a lot, here size is more
of a constraint. This, among other causes, brings the entity responsible
for planning the roads to build them optimized at first - as few lanes as
possible. Over the past decade we grew and our commercialized &
industrialized center of the country became denser and denser with
population, which gradually brought the need of wider roads. One ring has
been expanded twice during 15 years. And it's the only ring we've got. On
top of this, this ring still suffers traffic.
But at least this one is well maintained. A lot of the infrastructure is
done by the lowest bidder, and that's usually the guy who can get the
cheapest labor. The cheapest labor around here is usually not as good as
the labor that values its time. This brings a lot of patch-work and brings
the roads to an even worse condition.
Looking at the States, it seems that no matter how wide the roads are,
there will always be lane-jumpers, as you've put it.
Another amazing thing is that you reached your conclusions by mathematical
thinking while I've been exploring this while studying for my BA in
Economics, and reached conclusions based on economic research. I wrote a
short paper (my final) in game theory that proves "watching your distance"
as an optimal strategy for sub-optimal-speed scenarios. In my model the
cause is biased time preferences which bring impatience and preprocreation
(or procrastionation) at times. (check out "Doing it Now or Later" By TED
O'DONOGHUE AND MATTHEW RABIN, I based my paper on theirs -
I find the traffic waves (I called them "traffic lumps", myself, and
prefer to ride between the lumps :) ) effect is caused by a set of
circumstance, rather than just the distance not being kept. While not
keeping your distance is the direct cause, people don't mind their
To clear up point "c", I'm sure some version of this happened to you:
you're driving close to someone's rear, your field of vision blocked, and
he hits the brakes. Boy, are you pissed. "What is he doing? What gives him
the right to surp..." you go around him with a sharp swerve of the wheel
and immediately see that he was cut off by some one who just barely
avoided an accident with a truck. Less angry now. But if you kept your
distance, you'd have a wider field of vision, and you'd predict his
actions and respond better yourself.
Another thing worth mentioning, I know of a sort of "Traffic Research
Institute" in Haifa, Israel, but I never looked into it. Hope this
enriches your hobby :)
Thank you for sharing your experiences and thoughts, and if you reached
this, for sharing my experiences and thoughts as well.
Please write back in case you have anything else that might interest an
amateur traffic observer :)
This is an interesting site with an unusual approach to concepts of science. It is very enjoyable.

I Just Read the 'Traffic Experiments' article and would just like to state that when one lane of traffic is closed by construction,traffic waves are not always caused by people who close the gap. But Instead by people who race all the way to the end of the lane until they are forced to merge by the cones. If people would just merge when it was convenient after becoming aware that their lane was ending rather than race along at top speed as long as possible it would solve a lot of construction related slowdowns. Note to the moderator. My Grammar is atrocious as I'm a speaker not a writer.

I am almost embarassed to say that I'm an electrical engineer. From my perspective, the SLI effect goes against my rational scientific thought. Some of the electrical theories on your website need to be clarified, but that task alone would take quite some time to explain to the average layman.
Here is my story:
I noticed for a long time that street lights would go out more often for
me than for others. I also noticed that more street lights would go out
when I was stressed. I've never had an entire line of street lights go out
for me, so perhaps I'm not as "powerful" as some who frequent this
website. For me, it seems like the same street lights will turn off as I
pass by night after night (ie on my way home from work). There seems to be
some sort of perimiter because as I walk up, there is an invisible line
that I can cross that will turn off a street light (this is definitely
repeatable). I have no idea why scientists have had difficulty proving
this in a laboratory experiment. Watches with metal wristbands actually
cause me pain in my wrist (similar to the pain of carpal tunnel syndrome)
until I take it off and then the pain slowly decreases (takes about an
hour or two to get back to being pain free). The electrical system in my
car has been wanky. I've gone through two batteries in a short amount of
time, and there seems to be an alternator problem as the lights flicker
inside my car and the headlights too. The alternator has been tested by
more than one mechanic, but the problem persists. I've changed the
headlights and tail lights as they burnt out which may or may not have
been related to the up/down voltages caused by the alternator problem.
I didn't tell anyone else about my experiences until I met a guy with the
same experiences (he's now my husband). My husband has the same problems,
but his wrist hurts more than mine when he wears a watch, so he doesn't
wear one. He's told me that he's broken watches before. He has also had
electrical (gremlins) problems with all of the cars that he's ever owned.
I'm very interested to learn if there are any other common denominators
between those who are SLIders. Does it affect health, longevity, etc?
I'm not psychic, but does being a SLIder give me a predisposition to be?
Is SLI genetic?

Something that might make an interesting addition to the vortex page: A new BBC show called "Bang Goes the Theory" have as part of their first episode created a 'new' type of vortex cannon. One that generates a subsonic vortex ring using a supersonic explosion channelled out of a cone with a large aperture, rather than by moving a large mass of air through a small aperture.

Your article with a potential explanation for the "pain" on the nails-on-a-chalkboard sound is great! I've been wondering about it for a long time and I agree that the screaming monkeys/infants theory is not satisfactory at all. When I hear these sounds, i.e. rocks scraping together, metal scraping a ceramic plate, teeth grinding, etc. I feel an odd sensation in my teeth, almost an irritating precursor to pain. It seems perfectly logical to me that some system evolved to activate the very sensitive nerves in the teeth whenever they are potentially being damaged. What all of these "painful" sounds have in common is that they are produced by abrasive friction between some hard material and a rocky/ceramic/enamel type material........exactly the conditions that could cause actual tooth damage in the mouth. I haven't munched on rocks lately and don't really want to but right now I feel like your theory is the one to beat. I hope it is actually tested one day.

How Do You Stop A Tailgater From Tailgating You? How do you stop a tailgater? Speed up? Slow Down? Change Lanes? Shout at him? Shoot at him? Most tailgaters are not trying to deliberately run you down. And if they are, better to jam on the brakes and hope for the best. Usually, they're just not thinking about anyone else except themselves. You need to tell him tailgating is a danger for you without offending him (if that's even possible). So here it is: Flash your four-ways until he backs off. Then wave to say thanks for showing you courtesy and respect. The wave is important. You're saying, "I knew you'd do the right thing." (He took a step in the right direction so applaud him for it.) Next, pat yourself on the back because you started a change in the world and did it in a loud but polite way. Works every time. I don't know why, but it works EVERY TIME! It may be because I'm asking for help instead of displaying anger (which they can mirror back to me) or because I'm publicizing his tailgating to everyone who sees us. But it never failed. (I actually now look forward to someone tailgating me so I can use this technique.)

Hi Bill, found your great info on static electricity and thought you might offer some insight into the PYRO-ENERGEN created by Junji Takano in 1968. His device creates a high voltage negative charge around your body that counters what he calls the "paranormal wave" which he says is from the "5th dimension". http://www.pyroenergen.com/process.htm A dry towel will do the same thing but less effectively. Is there anything to his assertion that you need a device like his so that you get a negative charge and not more positive charge. And what about the notion that arc welders are healthier? Thanks, Keith

I just ran across your article on electric people. It was with much relief that I read of others like me. I wear a wind up watch due to the problem with batteries, I have to replace cell phone batteries at least once a year, and PCs only last about a 18 months before the blue screen of death. I work in IT, we've figured out that if I don't touch the PC, I use a wireless keyboard and mouse and replace the batteries every couple of months, things are better. It is frustrating and inconvenient, more so because everyone thinks you are nuts. I believe there may be a genetic component as my grand-mother used to complain about the life expectancy of watch batteries and my daughter has just given up on wearing a watch, she can't afford to keep replacing batteries. This is anectdotal though. It would be interesting to have a study done on familes to see if there is any genetic component.

Hypothesis re: Radiant Energy, Dark Energy, and Dark Matter No one knows what Dark Energy and Dark Matter really are. I believe that they both are a form of Radiant Energy. I think that both are in different stages of revolving back to a semblance of their original Mass or Matter. I believe, contrary to accepted belief, that both have positive energy rather than Negative Gravity. I can visualize Dark Energy exerting force upon celestial objects and increasing acceleration of expansion of the Universe. I hope to solicit comments from others relevant to my thoughts. I also hope that the improved Hubble will give much greater insight into what has happened to our Universe. I believe that technology exists to utilize Radiant Energy to solve the World's Energy problems Joe L. Ogan

Hi, Bill.Thank you so much for your very informative writings about electricity. It has helped me understand a lot of things that I had erroneous concepts about. I am not a Scientist but I have always had a very deep interest about the origin of the earth. If you are interested, I would like to tell you a hypothesis of mine about Radiant Energy, Dark Energy, Dark Matter and how they relate to our modern day exixtence. Thanks again. Joe L. Ogan

Is there a suppression during a time of need, this makes no sense for our future is at risk!!! There are free energy technologies and Permanent magnetic motors, if each house had a permanent magnetic motor to power the home and we drove electric cars. There would be hell of allot less greenhouse gases being emitted. If you can understand this next bit then welldone if you cant then think harder! DRAW this, 5 evenly spread lines coming out from a center point each tipped with south poled magnets as the base is north then have 4 evenly spread SHAPELY curved double poled magnets(north-south) on the outer. Using the right stretched,half diamond cured inwards shape outer double poled magnets and materials this pattern in general could be redefined to make MANY different types of magnetic motors.Can you think of your own? i have dozens in my head its so easy!simple ideas are usually the best ideas! Using the right combination of old and new technology with enough static energy to overcome part of the laws of diminishing returns THIS WILL power something usable, such as a house, car, generators and much more. If you have drawn it right you will have one inner south poled magnet in the center of one of the double-poled outer magnets while two of the inner south poled magnets are attracting the other two are being repelled this then forces the one that is in the center to repelle at its thickest part of repelling.3D runs through the outer magnets just something i come up with years ago. C.S.I.R.O. Australia has one that can produce 3 500rpm, is there no investigation into this if there is then were is it? Does anyone out there know any thing about this besides a select few. Josh. M. of Western Australia,Mandurah i am Australian aboriginal from Broome and i'm sure i wont benefit from this. aka (munky) hope this is'nt to much info for your little brain to process.

Have you, Bill, or your readers, seen schematics for an electronic device use to copy homeopathic remedies, "potentize" them, or make them from raw substances? And/or how does one select the potency with such a device? I've seen one used, but I don't know what was inside. It looked like a coffee mug warmer, a little platform onto which was placed: (1) a glass vial to receive the imprint; (2) substance to be copied (either another glass vial bearing an energy pattern, or a raw substance). I'd like to try making one myself. Seems closest to Benveniste's digibio and may try Rick Anderson's circuit, with white noise, or just EMF pulses as sharp as I can make them.

In response to your beautiful insight on "How are Watts, Ohms, Amps, and Volts related ?" I have a question. I am an amateur but heavily enthused and pushing full speed ahead into the realms of electricity. My curiosity is this, As more current flows through a wire, and this causes ( I assume ) some proportional increase in heat, Does this also cause the field around the wire (of 'electrical energy' , watts or joules per second if I am correct) to proportionally grow larger or smaller in diameter in relation to in increase or decrease in amperage ( or resistance ) - aka heat ? And to clarify technicality, is it safe to say that the 'electrical energy' around the wire forms the shape of a torus whose inner most layer ('the doughnut hole') is 'perfectly' butted up against the outtermost layer or 'skin' of the raw wire itself ( taken for granted the physical presence of the insulation around a wire in this case is completely neglected by the 'electrical energy' or field of joules, as if it - the insulation - does not even exist ) ? I hope these make sense.. I'm growing terribly fascinated and would appreciate any depth of response. Thanks, Mark

Bill, hi. Very good articles, trying to put all the dots about the 'i's. However, you don't explore the fact that we don't understand what an "electric charge" or "electric energy" actually is! Fundamentally, we have no idea. You do give a sort of a definition to charge by saying it's "sybstance-like", but that's not really an explanation. On a basic level, we talk, use and produce "electricity", but really have no idea what it is...

I have combed the internet looking for definitive illustrations of why tailgating isn't just bad manners, dangerous, and a contribution to congestion, but is really of little-if-no benefit to the person who is tailgating. I can't find anything! It would be great to show illustrations of "angles of escape" (during normal driving conditions) showing how the closer you drive to the person in front of you relative to the speed at which you're traveling, the more trapped you become, the less your field of view you have around the car ahead of you, and the more stress you heap upon yourself as a result of having to be wound up enough to always react that much faster than those who keep a good distance back (and can relax that much more as a result). Here's a good analogy: Picture playing tennis the normal way, then try playing it on the same court, half the distance from the net. That would prove challenging and even frustrating, yet tailgating while driving is a lot like that, and people don't seem to realize it. Pretty please, with sugar on top: Create some illustrative diagrams?? I don't have that talent for programming applets or drawing illustrations on the computer that you do, or I would have done this myself and shared it all over the internet.

Has anyone else toyed with the idea of an electric gun? Basicly a solenoid for a breach. A crude setup is a 35# coil wound around a none conductive breach and using any smoothbore pipe as a barrel. The charge to the solenoid is basicly a car ignition system. The ammo is simply a bit of iron bar to fit the bore and you eliminate the dangers of storing and manufacturing cordite ect. Thought i'd offer the idea to you guys in the USA to tinker with as you have so much more freedom to play. Us brits play with guns responsibly and we are instantly labelled terrorists by the socialists in charge. Somebody get me a green card & a lab, maybe our heroes could have reliable kit. Sorry, last bit was my rant against comrade brown.

Diesel-electric locomotives. As the load increases on the traction motors, more power/electricity is needed from the generator/alternator, in turn making the diesel engine working harder and harder. Why? Is there some resistance building up inside the generator as demand for electricity increases? Please help.

Hi Bill, Great site! I learned some tricks I've not seen before, and I've been trawling for info on my Wimshurst for ages... I love the pop bottle motor, I'm going to try that! But regarding a power supply for it, you mention that a Tesla Coil may or may not work. Well it depends on the coil - typical coils are air-cored and charge-pumped by a fast DC pulse, not AC, so it makes sense that any ungrounded capacitative surface will get a bias over a grounded one in the field of a working coil, as the field is biased. Bearing in mind that a sizeable coil can put out kilovolts of AC / Pulsed DC, its going to induct a fair bit of that into the plates. If the coil is charged by an AC wave instead of a DC pulse, then there will be no overall bias and the ungrounded plate will not charge, and the motor wont run. Tesla was experimenting with tuned coils to transmit power through the air to boats hundreds of meters away, before his death; there still exists a tower intended to house the transmitter on the US coast somewhere. I should look up where ;) Jez

Bill, thanks for the simple generator instructions. We made one with two magnets that I ripped from a microwave someone left by a dumpster. After an initial design with some problems, I used your debugging and placed the magnets in cylindrical sea salt container and used the solenoid you recommended (actually pried it apart with a regular pliars and screwdriver). Anyway, worked like a charm. One little twist lights the recommended bulb just fine. Keep up the good work.

Hello Mr. Beaty !! First of all let me wish you a Happy New Year 2009 !! I found your article to create a disgustoscope on the web. I do have to tell you, that in 1988 already manufactured caleidoscopes in the way of your disgustoscope already existed. They called it Octoscope (or something like this). I was strolling around mid eighties, definetly not after 1988 in the city of cologne, where i was visiting some friends of mine. And I found a shop called TRAUMSTERN. A crazy little psychodellic shop runned from some, this is what i think some old hippies (the way they look like and what kind of stuff they are selling). This little shop did have a lot of fascinating caleidoscopes. Kind of I never saw before. And this Octoscope, what I bought was produced/manufactured from Apres la Pluie, 4950 France (thats what is printed on the tube, which covers inside the octoscope, which is made out of metall, with inside, sure you know, the three mirrors and a lense at the end). I and all the other people, looking through it, still have a lot of fun with it and I do agree that you have to use it outside. Better reflections. After all of this years it is a little damaged (but still working), thats why I researched on the web to find this guy/artist/factory who created this. I guess I have to take care about it myself to get it fixed and cleaned up. If you have any questions please feel free to contact me. Bets regards Gerald Brech

Oklahoma City, OK USA - Wednesday, December 24, 2008 at 11:29:08 (PST)
Your article "Incandescent Bacteria" describes hyperthermophile and hyperbarophile (a word I just made up meaning "high pressure-loving") bacteria that do odd, for bacteria, things like glow in the blue and UV parts of the spectrum. Suppose they do so for the same reason that "ordinary" life glows in the IR part of the spectrum; the extremophiles' metabolism runs so fast that the blue and UV photons they emit are their equivalent of "body heat"? By the way, have you considered such lifeforms as the cause of the anomalous high-energy optical output of sonoluminescence in water? Considering the anomalous light output only comes at the pressure peak of the effect, it would make sense if the little bugs' spores were present everywhere in water but only come fully alive under the severe pressure transients induced by sonoluminescence. If their metabolism indeed runs much faster than does that of ordinary life, they could experience many life cycles in the duration of a single pressure transient. It might be interesting to do a bioassay of the water used in a sonoluminescence experiment before and after running it for a while.

Bill, I need to have some philosophical discussuion with you involving Lichtenberg figures and their potential uses. Bert doesn't want to hear me. I know that you are open minded and I think we could rise above the common mode of obstacalized thinking and really look at this phenomenon from outside of the box. If you're interested, please let me know. Shannon Klasdja Intelligent Innovations

Thanks for info on electron energy flow. If the energy is flowing at the "speed of light", then there is no "friction"? So what causes cables to heat up.

Bill, just wanted to say Your explanation of how transistors really work was Great ! I've been searching for answers...trying to figure it out and stumbled across this site. I do have a question/misunderstanding. It seems that everyone, including you say that a transistor is, or can be an amplifier. I still find this difficult to comprehend. It seems that even though the transistor is opening a gate with a small voltage, in order to let a large current flow through it, The transistor in and of itself is still just a switch. Without the other power source at the collector/emitter, supplying the voltage and charge flow, the transistor is not actually amplifying anything ??? To me an amplifier would be a device, lets say a magical water pipe that I could put water in one end of it at the rate of 1 gal per minute, and it would come out the other end at 10 gal per minute ??? Now if I have a pipe with a valve and my hand acts as a devive to vary the flow rate per minute from 1 to 10 I wouldn't call my hand or the valve an amplifier ? But it seems that with transistors that what people say ??? I'm kinda lost ??? If anyone can give some explanations I'd appreciate it. Thanks, Jeff

Sincere thanks from another "Babylonian". The maths outputs can always be had by trial and error, once the physics makes sense. But to have to find the physics by trial and error is to forever re-invent the wheel. Common sense explanations like yours are what truly allow us to see further everyday, by standing on the shoulders of those who DID find the physics by trial and error. most gratefully Robert

Regarding the nanoammeter described on the following page: http://amasci.com/emotor/nanoamp.html I've got a use for this nanoammeter. I'm a mechanical engineer and I work with electromagnetically actuated and sensed micron scale devices. The output signals are in the 10s of picoamps to 10s of nanoamps range. What I'm not clear on with the setup is which comes first the ammeter panel or the voltmeter. If anyone can help out with a clear description of the order of things I'd sure appreciate it. If it's easier to email a simple sketch (MS Paint?) then that would be great as well. Many thanks in advance! Fred

I live in North America, but I am going to be spending a year abroad in Israel. I would like to bring my laptop with me to use while I'm there, and since they have different plugs, I bought an adapter (not to be confused with a converter, my computer will be running on the Israeli 220V instead of the North American 110V). The thing is, this adapter has only two slots, while my laptop plug has three. I mentioned this at the store, and they assured me that it would be fine to plug in the two prongs and let the third stay outside. Logically, this should work as far as charging my laptop, but is this safe for both me and the device?

Also i would like to make a larger scale model of the generator using super magnets but i dont know where i could get a custom made super magnet the size i want. and one more thing, where can i get a lot of solenoid wire and i mean a lot(maybe over 600 turns under 5000?). Thank you and keep up the good work. because of you physics seems fun :).

this is a response to your "Threadlike electric wind" post. what you have created is actually a tool used by particle physicists called a cloud chamber. it is used to visualize subatomic particles. because the dry ice is so cold, you have air that is supersaturated with water (kind of like a cloud). in a cloud, raindrops form around what is called the nucleation point. it is important to note that usually this consists of small dust particles, but raindrops will also nucleate around subatomic particles, such as electrons, positrons, protons, and any other particluate-based radiation, including alpha and beta particles. when these drops form, they pull water vapor out of the air, leaving a 'contrail' that you can see. these are the 'threads' (this is why your negative ion generator was so effective) (note that these particles are passing through or around us all the time) a more effective cloud chamber can be made by placing a glass tank on a layer of dry ice, and draping an alchohol soaked felt strip around the top of the inside edge. the dry ice helps to supersaturate the air with alchohol. cover the tank, and wait a few hours for it to get really cloudy on the bottom. interesting experiments to try include using ur neg-ion generator to shoot particles around a magnet (the magnet should cause the normally straight path of the particles to veer off to one side. enjoy!

Bill re your article of telsa's big mistake it seems that you where not far off the mark with your thoughts please see below an actual result of this theory. Schematic of the experimental setup. A is a single copper loop of radius 25 cm that is part of the driving circuit, which outputs a sine wave with frequency 9.9 MHz. S and D are respectively the source and device coils referred to in the text. B is a loop of wire attached to the load (light bulb). The various srepresent direct couplings between the objects indicated by the arrows. The anglebetween coil Dand the loop A is adjusted to ensure that their direct coupling is zero. Coils S and D are aligned coaxially. The direct couplings between B and A and between B and S are negligible.
Using self-resonant coils in a strongly coupled regime, we experimentally
demonstrated efficient nonradiative power transfer over distances up to 8
times the radius of the coils. We were able to transfer 60 watts with 40%
efficiency over distances in excess of 2 meters.
Bill, I have Just read your article on Tesla's big mistake, and wow what great insight. Could you tell me if this is related in any way to Scalar waves, which many have postulated is the radiant energy Tesla called the ether

I have spent about the last 20 years trying to make a static electricity machine with only intermittent success: because I don't understand how they work! Anyway I have managed to distil one idea from of all that, which is that you can make a belt-pulley out of a bulbous plastic pop bottle. You can drive it with a hand-held battery power drill by attaching a screw to the pop bottle lid which you can put in the drill chuck. And whoever is holding the drill can stand on insulating foam & tension the belt manually, also wipe something on the moving belt with his/her free hand. But I just don't understand the physics! Knew for certain I understood it at school but now am a sadder & wiser man. Can you help?

Hi I am commenting about your Traffic Wave article. I am from Australia. I have been driving with what I call an "Air Buffer/Gap" (2 or more car gap) for a good many years. There are 2 reasons for it. 1: I drive older cars and I do not trust the brakes. I like to leave room just in case something goes wrong. 2: I do not like stopping or gearing down into first. The car does not like first gear either. I drive on city roads like the car is a ship, if I see red-lights (traffic or cars or any other possible hazards) I slow down so when I get to that point, the road is clean and I can keep the vehicle moving. I find it refreshing that you have a web-page about traffic flow. Especially the video where you demonstrate good driving. There is a driving school in my building and I am going to recommend your web-page to them. You sir, may have influenced a generation of calmer drivers. I would buy you a drink but I fear a Postie would get to it first.

I just read the article about the woman and her daughter "hearing" radio frequenciesand it was a breath of fresh air to find that my siblings and I are not alone. We also have the ability to sense if a television is on without the volume on or seeing it. Some television signals are stronger than others to the point that I can't even stand it being on. Most televisions are tolerable but will cause me a headache after awhile. I never knew anyone else, besides my siblings, that was able to do this. That left me feeling like a freak. I would explain it as a painful fuzziness in my head. It's comforting knowing that there are others.

About three weeks ago my roomates sister was at our house doing her hair before work. She called him crying, and said that it sounded like a truck had driven through our house. The whole house vibrated, and she thought it was an earthquake. This lasted about 20-30 seconds. Our surrounding neighbors rushed over to see what had happened. One reported that he saw our whole roof shaking. My roomate rushed home to inspect the water heater and any other suspect areas. Everything was perfectly normal. I was intrigued as to what the source was, speculating that the hot day caused our 90 year old house to suddenly settle in some wierd way. Nothing happened to any of our neighbors houses. I havn't thought about it in a couple weeks, until I came across an online article in Fortean Times today. I then realized how many people actually have heard this. Our case seems to be one of the most intense i have read about. It seems stronger than the Taos hum. We live on a large hill in Tacoma, WA. There is a railroad about a half mile away in a valley, a few hundered feet lower than our house. We also live within a mile of Commencement bay. Has anyone every felt a localized earthquake like this?

Bill, Thanks for introducing me to hand drawn holography. I have made several "holograms" now, and some of them look pretty good. Perhaps due to lack of patience, I had trouble implementing your solution to the problem of scratches obliterating each other. I found an alternate approach that I'm sure you're already aware of. I have found that the under side of the scratch works about as well as the upper side in producing a spot of light. Using thin, clear material (I'm using .06" thick polycarbonate), you can divy up the scratches so that some are made on the upper surface and some on the bottom surface of the plastic sheet. By planning, you can thus reduce some of the obliteration that goes on when you have a lot of points. For example, if you are recording a word, you can put every other letter on the back surface. By using this same idea, you can make a two "color" hologram. Say the thin plastic sheet is tinted blue. The scratches on the upper surface will produce white points of light while the scratches on the bottom surface will produce (somewhat dimmer) blue points of light. The thinness of the material minimizes any refractive displacement. Thanks again. Don

Just read the article "Cognitive Processes and the Suppression of Sound Scientific Ideas" by J. Sacherman 1997. I was thrilled to see in print the ideas he expressed on the issue of scientific community being very closed to new ideas or challenges to popular and accepted theories. It was dissappointing to see the references to Darwin and evolution included in the arguement, when there is so much clear, observable science that contradicts the theory, and yet even in the article, the 'theory' is supported as fact by the author. Why do you think the scientific community today is so opposed to solid science that refutes evolution? Why are any facts that raise serious questions to the theory thrown out as 'bunk' or the scientist who put these ideas forward dismmised as 'fanatics'?

I am ABD in pure mathematics working for the Army Corps of Engineers on devising an Arc Flash Protection Program and found your site very useful. You made me sad, however, when you described math as a "useless tool" and "a bunch of recipes" , a "crutch" for those who do not think like the Babylonians. True math has nothing to do with equations and recipes, it is about understanding the properties that are important and relevant to a particular problem, abstracting them, then connecting them to other mathematical objects. Equations and Formulas appear sometimes in lower mathematics where coordinate systems may arise as a consequence. The formulas are only there to make the physicists and engineers happy. I don't know if I speak for all mathematicians, but the ones I know, love to find connections and figure out why the relationships work the way they do. Once they see the connection, they would just as soon throw out that problem and go to the next one. I hate having a board full of equations. It is the explanations of what they mean, and how they connect to the objects we are studying that are really important. I am sorry for the epic, and I'm sure you will never read this, but I wanted to defend the field I fell in love with when I was 4 years old.

Good Evening Sir. First of all, I want to say you “Thanks”, for giving me, your costly time. Sir I don’t want to waste you time and I don’t want to disturbed you. If I disturbed you, then I say, “I am sorry, Sir” My self introduce to you as Balram Tiwari, student of BSc 3rd year in G.N.KH.College, in Yamuna Nagar, in Haryana, in India. Sir 3 year ago I wrote a research paper on the topic Origin of Gravitation by Nebula Hypothesis. I had done my best to publish this paper to Science Magazines. But it is my bad luck that no one helps me for publication of my research paper, in India. I don’t know my paper is correct or not. But I know that my research paper is based upon Laws of Physics, which is made by Sir Isaac Newton. No laws of physics are invalid in my research paper. Sir I had spent 3 year in study my research paper by my imaginational universe. After it my research paper could not made me a scientist. But my research paper made me a mental. This is not told by me. These words are told by people that are connected with me. I read your History of Research and Development of nuclear gravitational theory and after study your work on gravitation and your Website, I decided to take your help. I am sending you this latter by hopping that, you can help me. I need your help urgently. I always considered “Sir Isaac Newton” as my ideal. I always trying to becomes like him. Sir my last wish of my life is to search origin of gravity in universe, by Sir Isaac Newton method. That’s why I want your help. But before this, I want to tell you some thing about me. I am a poor student of BSc. I had got 47% in 1st year; compartment in second year and for 3rd year, reappearing for exams paper. I belong to a poor family and I have no capacity to clear even entrance exams also. Because I am a poor student of science as shown by my results. I have no capacity to clear my BSc Class as I belong to a poor family in which no one at job. Only I am at job in a private school at 10 dollar per month. India is a poor country and job and study facility are only for middle class family and reach family. I want to make my self like a famous scientist. In Japan, a student of BSc. got Young Scientist Award 2005, for the research for DNA formation. But In India it is impossible. But my Last wish of my life is to make my self a brilliant scientist. I don’t know my wish is fulfill or not. If possible please help me. I want your support. In India, I got only abusing of people, mentally pressure and wondered person. I don’t want to take your help freely and with out competition. You can take my online interview about my study and knowledge. I become your servant and serve you till my death. You should check my knowledge. After it, if I able for you then give me your teaching support. other wise you can say me “No”. I have no money, for come to your country, I pay all fees and all price, by part time job. And work for you as servant. I think that, no body can take risk about me. If I am at the post of you, I also behave as you behaving with me after study this email. Sir please doesn’t take any tension about me. I don’t want to disturb you. I told you every thing truly about me as “Honesty is the best policy”. Sir no one can understand my heart feeling and my struggled full life. Sir please helps me. I need your help urgently. Otherwise my life and future are destroyed in this hell country. I am just waiting for your email. Sir please replies me, weather you say “Yes” or “No”. Only one word by you can change my life.

I have for some time been a happy reader of these various pages, and grateful for the excellent clarifications of electrical theory. I've recently got a bee in my bonnet about building a simple but modern steam engine, and quickly discovered that generating the steam is the tricky part. I'd like to generate the steam on an instantaneous demand basis - being easier to control and using probably fewer weighty parts - so I thought maybe microwave flash boiling would be worth a try. I noticed Bill's comment that 10 GHz was closer to the "water opaque" frequency, confirmed this for myself at atmospheric research pages, so started looking for cavity magnetrons (or SOMEthing) to generate around a kilowatt of RF at in the X-band. (It's OK, I'm a VHF and UHF radio tech with over 40 years of experience, no longer working in that field, but I won't hurt myself.) My question, after that rambling intro, is this: how does one generate that much power at that frequency? I'm stymied; I can find no useful info through google; it's almost as if the web has been purged of such info. Maybe it has? Anyway, can anyone help with this? I thought at first that I could just buy a device and power it up, and that my biggest problems would be pulse width and duration for effective steam, and figuring out what to use for the microwave window into the combustion chamber/boiler. But I can find no such device. If anyone can point me towards one, they could be instrumental in helping get the first steam aeroplane into the air since Bessler in the 30's!

Hi - Excellent site! Enjoyed your electric charge detector article. But not sure about the statement "it really takes no energy to turn off the FET". Surely the electrostatic field results in a force on the electrons, which move aside as a result. Force x distance moved = work (energy expended). The net electrostatic potential is slightly reduced as the electrons are now further away from the gate. Or am I misunderstanding this?
[To a first approximation, an FET gate is a capacitor, and capacitors use no energy. Yes, you can store energy in them, but you get it all back again. So, it takes energy to turn off the FET, but that energy is returned when you turn the FET back on again. (Second approximation: it's not a perfect conductor, so the tiny currents in the Gate circuit do have tiny losses because of heat. -billb] Cheers, Laurence.

Good job on your web site ! I have had a blast lookin through and its nice to see some of that good ol fashion hardware hacking! I am a newby to this site and have always been interested in HV Tesla and anything that vibrates. I am an electronic musician and have been curious of phenomena wilst tinkering with everthing plugged in ~ guitar strapped on and on concrete with bear feet! Thank god i survived! But that was when i was a kid and i see the importance of passing survival to the new curators and caretakers of this amazing bubble we live in. So now i see an emerging brave new comunications frontier and the window is about to bust wide open. Somehow when we play with are toys, thats when the REAL science shows up and some of us notice the the guy on the other side of the fence! I think with computers,music, and high votage we can relearn the lost neuro net we had when we were living in the caves and in Mesopotamia! Let us play and teach the way to our future. I believe that this very essence of self and our relationship with our mother earth is about to invent the solution and it will be through the clever vines the bushies will never understand, nor will they enslave us anymore.

On your IR goggles, in _The Human Senses_, 2nd ed., by Frank A. Geldard (pub. John Wiley and Sons, New York), pg. 21, it is stated: "Reliable measurements of visible light, involving very high energies, have extended into the ultraviolet to wavelength 312.5 nm and into the infrared to wavelength 1050 nm. ... To see a light of wavelength of wavelength 1000 nm ... there is required a source 10 billion times as strong as that needed to see a light of wavelength 562 nm." While the phrasing seems odd to me, the context makes it clear that he is referring to the seeing with the naked eye of such light. No references (eg, to experimental reports) are given for these claims. I am also not sure whether, these claims refer to a simple binary yes/no, or if an differentiation of intensities was made by the subjects, nor if actual images were reported by the subjects. This certainly suggests, though, that with extremely bright light sources, pushing further in to the infrared than you have already tried is a possibility.

I've seen that you know the Carver Mead's "Collective electrodynamics". It's a good and new look on electromagnetic theory, very "cutting-edge". But do you know the theory of Milo Wolff, on which the Mead's book was based? It's the Wave Structure of Matter theory and it treats electrons as waves made in empty space. Here's Milo Wolff website: http://quantummatter.com/ He wrote a book explaining his theory ["Exploring the Physics of the Unknown Universe"] and recently he published part two of it, more about electronic waves, quantum physics and Schroedinger equation. BTW I've seen also that you're making use of A field [vector potential]. I very appreciate it, because in the Internet and books there are a few info about it, and it's very pity, because this field seems to be more fundamental than E and B fields. Still much students of physics I've talked have objected that in toroidal coil there is A field present and it's not directly the B field which induces the current in secondary wire. I really appreciate your Tesla articles too, because his inventions appears to be very related to A field.

I was married at 27, had my daughter at 29 and was widowed at 31. My husband had smoked for years before I met him and continued throughout our marriage. We were excited over his being appointed Press Secretary for a newly elected U.S. Senator from our state. We had moved across country from Seattle to Washington, D.C. just six-months before he became ill. Amazingly, that day in June started out like any other, except that I had agreed to pick him up from the subway station at a D.C. suburb. He had become so confused on the train that he couldn't remember which stop was his. His co-workers would later tell me that he had been acting strangely the past few days at the office (not quite like himself). The strange behavior - the doctors later advised - was due to a severe potassium depletion caused by his illness. My husband was diagnosed a few weeks later, but first had to suffer the indignity of spending a night in jail and several weeks in a psychiatric hospital while they tried to figure out what was wrong with him. It wasn't until he asked for a chest x-ray that we discovered he had a quarter-sized darkened area located toward the center of his lungs. We thought ok, now we at least knew what the problem was and (besides), people could live with one lung. We were buoyed ONLY temporarily. When the diagnosis came down it was; small cell lung cancer, inoperable and fully mytastisized. We came back home to our family and friends in Seattle, fought hard, celebrated our last Christmas together and I watched my wonderful, sweet, gentle husband try to say goodbye to his baby daughter. His Masters Degree in Journalism from Columbia University offered little help to him now. My husband died 25-years-ago this last July 4th and I still think of him at least once every day. My daughter looks astonishingly like her dad although he promised otherwise. But possibly the saddest part of this story is that my beautiful, funny, smart 28-year-old daughter, has been smoking since she was 16. I remember what went before and worry about her everyday.

I am currently in contact with REVA an electric car manufacturer in India and am helping them extend the mileage per charge. Cooperation in the USA on this is doubtful. Based on the molecular properties of water there is a way to calculate the electrical energy output that can be expected (I have tried to find but can't). Kelvin's Thunderstorm is an experiment where you can measure the actual output. However, if the experiment is reduced to its simplest form where each drop is a molecule what would be the theoretical energy output of each molecule given 100% efficiency? What is the formula to calculate this? My email is wooten4615bellsouthnet.

Is there a way you can make it so under the UNUSUAL PHENOMENA REPORTS : ODD ANIMALS people can add photo's of what they saw if they have any? Thanks.

Hey, i was reading about your IR goggles! I thought you might like to know of a few other sources for your lenses! 35MM cameras have adapters for IR filtering (and blocking, it's quite cool!), but those attachments to existing lenses can be expensive (but the optics are strictly IR only!) another way to do it is to buy a roll of film, or photographic paper and don't expose it to any light. instead develop it right away. you'll get a black sheet of plastic (celluloid or whatever the large photographic paper is made out of, as well) that only allows IR through. If you have a friend in college that's taking a photography course, they should be able to get you the sheets for free... but if not, you can buy a roll of 35mm film and just use that, too. Hope this helps! :-D

Thank you for the great idea for viewing magnetic field patterns in 3D! I tried it out for my 2nd grade science project because we are learning about magnetic fields.
