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

I hope that one day some one will figure out why people like myself , when we get upset , afraid, anxious, can turn street lights on and off. Blew out telephone lines,and on and on, and when a scientist built a machine that only I could not touch , because I would kill it, thats pretty weird. I am a medium and can read people as well as many other special gifts. Could that be why I have this weird problem ?

We are putting most of our training online (Environmental Health & Safety at Univ of NE-Lincoln). Our Director found a picture of electric charge & electric energy on your site and would like to include them in our General Electrical Safety (non-qualified person). Is that OK with you? Can go to url above and view some, e.g. Ladder and Mobile Aerial Lift that we've done most recently. Thanks for your consideration.

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.

Hi Bill -- Holography can also be done via computational mirror design. With the right geometry, you can get distortion-free 3D, animation, & ultra-wide field of view. Some example artworks at http://www.zintaglio.com . BTW, a colleague arrowed me to your site with high praise.

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.

Hi there, so this whole thing is driving me CRAZY right now, another power blackout in my area, and like Jeff everything electrical stops working where ever I am! And I can't find any help or information or explanation and I am feeling quite upset about it. I am glad that I found this site because I started to think that I am the only one with this crazy problem. Thanks for listening. Judith.

Hi there, I came across your site the other day. It is nice to see other people are also having this stuff happen to them.

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!

Thanks Jeff

I LOVE your traffic waves explanation! Unbeknownst to me, I had been doing this for years to make a less stressful drive for myself (braking, tight spaces) and now see the benefit for not just myself but everyone else around me. No rushing to keep people out of my lane, everyone can come and go as they please around me and I lose little to no time and can have even less of a chance of being in an accident due to rush hour. Thank you so much for explaining this, as I try to pass this information on as often as possible.

Hi, I looked over the cure that is on your site and it may work for some. I am both electric types and very electrical effecting highway lights, stores and appliances. also constantly getting painful shocks. holding keys in my hand only makes the electrical shock hurt more. i cant go through Walmart without my fingers hurting by the time I get out of there because all of their shelves and door handles are metal. 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)

Err, I kind of need help and none of your links work. Been researching this ever since I accepted I had a problem.
My mood directly influences the operation (both positive and negative) of electronics - mostly computers (I'm an all round techie). Broken stuff will start to work and good stuff will just stop. No touching needed, but must be within a few feet. I'm not mad.

Southed on Sea, UK - Friday, August 20, 2010 at 20:30:33 (PDT)
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 electrical energy. [ 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.
Exhibit A:
"Make another cut in the metal ring, install a light bulb in the cut, and then the "friction" of the narrow light bulb filament against the flowing charge-stuff creates high temperatures, and the wire filament inside the bulb glows white-hot. The battery drives the ring of charge into motion, the charge moves along like a drive belt, and the light bulb "rubs" against the moving charge, which makes the filament grow hot. " [ http://amasci.com/elect/vwatt1.html ]
Exhibit B:
"For example, whenever a battery powers a light bulb, the battery spews electrical energy into space! The electrical energy is then grabbed firmly by the wires and guided by them. The energy flows parallel to the wires, and eventually it dives into the light bulb filament. There it drives the metal's charges against the resisting force of electrical "friction," and the electrical energy gets converted into thermal energy. " [ http://amasci.com/elect/poynt/poynt.html ]

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...

Congratulations, nice web site, I stop by every now and then for a dose of relaxing science. GRAVITY IN SPACE misconception is interesting for an orbiting space shuttle. But why is there no apparent gravity when apollo 11 was going to the moon? If the source of gravity was acting from behind, why didnt the astronauts drop food on their shirs? Was the gravity from the moon cancelling out the gravity from the earth? Cheers!

Found some of your pages regarding "energy sucking antennas" recently, and some of the forum interchanges regarding. I probably haven't found it all, so maybe the following is covered somewhere... 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 all the info you host on this site, I have enjoyed reading through it at various times over the years.

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.

Bill, has there been any further data on the safety of your IR goggles? I'm an educator working on a project for the Seattle Aquarium (funded by NASA) with the theme of Exploring Ocean Science From Space. 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...

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.

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. Your precious time will automatically be allocated correctly for maximum benifit to all. Sign me up as the first customer- I *wish* I could pay $100 for a few minutes for your time! Please?

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 planet.

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.

Ref: 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 experience.

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 the surface.

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.

An experiment:

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 your ear.

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 slope.

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, and pressure.

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 the Nile.

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 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

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.

"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. "

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 ?150 (approx $225) of fuel per year... Sweet. Keep up the good work! -John

Hello, My Name is Tony Devencenzi. I am a retired instrumentation designer and an amatuer scientist. for the past five years I have been doing a research project on a discovery that I made involving naturally occuring ultra low frequency waves and have performed may experiments that have lead me to postulate a theory that is based in the belief of an aether. I am offering all of my research, details of experiments, virtual instrumentation software that I have written, schematic diagrams, etc, to anyone who is interested. I have just put all this with download ability, on my new website aetherwavetheory.com I am not selling anything, just want to share all of my work. Please let me know if you would link to my site, or if you would like to have copies of my files or pages to share with people, to place on your site. Thanks, Tony Devencenzi

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 - http://www.uibk.ac.at/economics/bbl/lit_se/lit_se_ss06_papiere/now_or_later.pdf)

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 distance because:
a. they are in a reasonable hurry/mindless greedy rush.
b. There is no communication between the drivers. Everything is taken personally and immediately so.
c. We tend to expect the status quo to last, rather than prepare for fluxuations, and until we see a reason we don't beleive there is one.

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 :)

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?

My eyes also reflect the light around me so when I go into a room without light I still see shapes and bright shinning lights, I tend to stay away from the sun because it bothers me so and Ill get a headach and eye pain, sleep is my only realife, what can I do if anything to stop seeing these unbelieveable things, please help. thanyou.

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.

I have been experiencing SLI for many years. Recently I had my microwave blow up on me, and this morning My coffee maker blew out with enough force it shot out a flame. My laptops have only lasted a few months and ever time I go to somewhere where they are using a computer they go down. I would like to use this energy to help others but am not sure how to do it. I am a professional parapsychologist. I also blow out street lights, and lights in my home, and many of our outlets won't work when I use them, but they will work for my husband.

It is generally accepted that Dark Energy and Dark matter fill 96% of space. What has happened to Radiant Energy which has been pouring into the space for 13 or 14 billion years? I can not find the answer to that anywhere on the internet. It appears that Dark Energy and Dark Matter must be some manifestation of Radiant Energy

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

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.

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. Good luck with all the projects folks. remember, a person in a shed has done more to change the course of history in the last 200yrs than any goverment

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.

I have just uploaded two better drawings of a WHALE'S TAIL windpower generator design, explaining the BERNOULLI PRINCIPLE advantage (thanks to Bill's work), and also incorporates Tom Kasmer's HYDRISTOR. I have just read that Bill is swamped with emails. Ideally, I would like for him to look at my webpage mentioned, and give to me his valued feedback. And, I also appreciate feedback from any and all who are interested in looking at this new and novel way to harvest energy from the wind. http://darinselby.1hwy.com/whalestailworkings.html

Great site. I was wondering if I could get a "Word" Version of the Ultra Simple Electric Generator? I work for an elctric company and we are doing a presentation for a Grade 4 class tomorrow and would like them to have a copy of this. But your site does not have a printable version, that I can find. It would be greatly appreciated. Thank you.

My paper, cited above, is an ongoing investigation of subsonic aerodynamics at the particle level. I'm only using Newton's laws between the particles and so calculating is a problem. (Avogadro's number is pretty large even for modern computers.) Thanks, Bill, for your model and for your intellectual honesty. This stuff is tough.

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.

My child is doing a science project and he loves your homemade electric generator. He is expanding the project to have a water mill turn the generator. What our question is after watching the electric generaror video is there any kind of blueprint or step by step instruction to the model built with the plexiglass and pvc? Thanks and my kid(5th grade) thinks you guys are super cool!!!

Hi there, very interesting site! Since you seem to know about electronics and Hall sensors, i have a question for whoever wants to respond: I am trying to convert a 0.25-2.5 Volts signal to 0-90 Ohms (its for displaying the contents of the LPG tank in my car on my cars fuel gauge). The volts signals is coming from a Hall sensor. Any suggestions? Please include henk.noordermeer(:at:)gmail .com Thanks a lot in advance (I know more about mechanics than electronics, hence this probably silly question.. can't be too difficult can it?)

I am sure you get sweltered with requests from your Science website. (I know it's late but I couldn't sleep) I am excited to use some of your examples for my eight graders! I could probably use a few for scouts too.. Anyways I know you don't like link requests but I would love to link up from my Eco/Science website. My website is http://www.keep-green.com But really if you don't care to swap links I completely understand but your site was still very nice - I will reference your site to my class. I truly appreciate your professionalism and response. Respectfully, N. Peterson

Brand Blvd. Glendale, CA 91204 In his latest book, award-winning science writer Dan Falk chronicles the story of how humans have come to understand time over the millennia. How did our species first become aware of time's passage? Could the "flow" of time be an illusion? Is time travel possible? Drawing on the latest research in physics, cosmology, psychology, and anthropology, In Search of Time is an extraordinary journey along a most curious dimension. ----- Carlos Marin JR Event Marketing Manager Zone 5-BORDERS 3700 Torrance Blvd. Torrance, CA 90503 W: 310-614-4168 | C: 310-614-4168 cmarin2@bordersgroupinc.com

You are a true Nerd's Nerd...a man with a small turbine engine on top of your beanie (where other lesser men merely have propellers)

I thought the scratch hologram stuff was great, and then I saw all other great stuff on your site, wow. You have inspired me, your website makes me want to be a better nerd (Jack voice there, unfortunately you appear to be chromosomally about as far from Hellen Hunt as it is possible to be ; ) ) Now I feel much more empowered to embrace my inner weird.

Now except for the fact that there appears to be no references to H2G2/Douglas Adams or Heywood Banks on your sight, Long May You Run Sir; or at least until you are chased off a cliff by a large pack of naked woman, of your choosing, or get the bad mousse, or end up in a life raft at sea some where, having to decide who is going to have to eat which part of whom and what condiments they would like with that)
