Thank you for this website! Yesterday night, I lay in bed thinking about electricity, and in particular about how bothersome it was that some aspects of electricity were still puzzling to me, even after having successfully completed an EE degree many years ago. As I mulled it over, I realized that my biggest frustration lay in my inability to reconcile the seeming contradiction between high-voltage static electricity and low-voltage circuits. In the former, excess charge will readily move from, say a Van de Graff generator sphere to a metal ball, without the need for a return path. Yet when dealing with batteries and lamps, we are lead to believe that we need a closed path. I got to thinking about whether it would be hypothetically possible to drain an AA cell using a quarter, by touching it to one terminal, then moving it to the other, and repeating this process over and over again. From the electrostatic viewpoint, it seemed plausible, yet from the circuit viewpoint, it seemed absurd.
While I do not still have an answer to this small thought experiment, this website has been spot on in identifying the issues that I have struggled with for so long and gives me confidence that perhaps I'm not as ignorant about electricity as I had previously thought. At least I seem to be asking the right questions!
PS: If anyone wants to comment on my AA cell thought experiment, please write to marciot at Y a hoo.

Dear Mr. Beaty,
My name is Pranab Jyoti Ghosh, I am an Indian
physics graduate and myself have theoretically developed a technology on
producing energy without any kind of fuel. This technology is about
producing energy by extracting heat from atmosphere. This technology is a
combination of processes that are well tested and now in use in different
industries and research projects. I have done everything that I can do by
myself. But for further advance, I need financial and technical
assistance. I am assuring you that this project is just need to be made
and improved. All the basic experiments had been already done successfully
and enough data had been gathered. In short, it is a new and exciting kind
of technology and as far as I know, nothing like this exists this day.
I am writing this letter to you to know your opinion about this technology. The so-called ?skeptics? have a tendency to just ignore when they are challenged. Anyone can contact me and I will supply him the necessary information to build this technology just after signing an NDA. He/ she will have all rights to test the technology and I will help him/her fully. But he/she wouldn?t have the right to patent it on his/her name and sell or license it in the market. Previously I have challenged skeptics in the same manner, but haven?t got any kind of response. I want to know what you are thinking about that. If possible, kindly refer me to some places where I can find skeptics and challenge them. They think that they only have right to challenge everybody, but I want to see them before challenges.

The women in my family do alot of weird things. My mother, as
unbelievable as it is, has almost been hit by lightening 3 times and it
was close like 2 feet away, each time. One time was on a clear day with
not a cloud in the sky and no lightening or anything. We all make watches
stop working and cause electrical outages in our house. It is nice to
know that there are others out there. Now, I do do the shock thing like I
will get a strong shock on some light switches and I have made the house
black out in sections and sometimes it's sections that are connected as
far as fuses and only half of it goes out. It happens most when I am mad
and happened alot when I was going through puberty. My fiance cannot get
his cell phone to charge in his vehicle if I am touching it or even within
2 feet of it. I have worked in an office and had computer techs tell me
that they can not figure out how I caused the problem that my work
computer has. I have had times when people used some electrical device
and it worked fine and I go to use it and it won't work properly or even
not at all. I can't wear watches and my ipod battery drains very fast.
I also shock myself on car doors and other things even more frequently
than other people. A jeweler once told my mother that we have high
magnetic fields. It always kind of freaked me out because I have no
control over it and I tend to break stuff by accident when I am mad.
Then again I have always had alot of unusual characteristics I guess this
one is just another on my list. How would I be catagorized.

yes, yes, yes. I agree with your findings totally.
i have practiced the leave-large-gaps strategy for years and it works. The
other offshoot of this is avoiding using your brakes unless you really
have to. The trick is to break the cycle of brake light triggering the one
behind it triggering the one behind it, etc. I'm convinced this is the
cause of 'phantom' slowdowns; no obvious cause.

I HAVE READ SOME OF THE STORIES ON THIS SITE, AND ALTHOUGH I HAVEN'T
TURNED ON AND OFF ELECTRICAL ITEM, NOT THAT I HAVE NOTICED, I DO GIVE OFF
A VERY PAINFUL AND 6" BLUE ELECTRIC SHOCK, MORE OFTEN THAN NOT, WITH
PEOPLE AND METAL ITEMS. I HAVE NEVER PUMPED MY OWN GAS, AS I NEVER KNOW
WHEN THIS SPARK WILL APPEAR AND AM SCARED THAT IT WILL HAPPEN THE MOMENT
TO TOUCH THAT NOZZLE.
AS FOR ELECTRICAL ITEMS, AS I SAID BEFORE, I HAVEN'T TURNED THEM ON AND OFF, BUT I CAN WALK BY A HOUSE AND TELL YOU WHAT ELECTRICAL ITEMS, SUCH AS A TELEVISION OR COMPUTER, IS ON. IN A HOUSE I CAN FEEL AND HEAR A TELEVSION AND SUCH BEING TURNED ON OR OFF, AND I HAVE RECEVEIVED A SHOCK A NUMBER OF TIMES FROM PHONES AND KEY BOARDS.
WHEN I WAS YOUNGER I THOUGHT IT FUN AND A GAME. NOW THAT I AM OLD, AND THE SHOCK HAS BECOME STRONGER AND MORE FREQUANTLY, I FIND IT NOT SO FUN. I GUESS I'M ASKING WHAT CAUSES THIS AND HOW CAN I STOP IT -- I CAN'T PET MY CAT, I SHOCK HER, KISSING MY PARTNER IS ALWAYS AN EXPERIENCE FOR A "LIGHTING BOLT" (AS WE NOW CALL THEM) CAN HAPPEN ANYTIME AND IS THE MOST PAINFUL.
GUESS JUST WONDERING IF THERE IS ANYTHING TO STOP IT. BUT I AM GLAD TO HEAR IT IS MORE COMMON THAN I THOUGHT.

I didn't see in your observations on traffic waves any
comments on the calming effect that a reduced use of brakelights has on
traffic behind you.
[That's because I realized that avoiding brakes
has only a small effect. If we compare it
to the problems created by normal speed mismatches, we find the brakes
aren't really the problem. Since nobody can
gas pedal set perfectly, we all will vary a bit and drift forward and
back. Even if you're moving slightly *faster* than average, you
guy in front
closely and need to slow down. Whether fast or slow, it
creates "noise" which builds up and *forces* others to use brakes
to avoid collision. When driving with close spacing, whenever all the
cars ahead of you hit the brakes, you have
no choice but to do the same (and neither did they!) No inferior "Nervous
are needed so long as the tiny changes in
speed get amplified. One person drifts backwards, causing the next person
to drift backwards more, the next more, and then the next actually has to
tap the brake pedal. Even if everyone is the same, and everyone is an
expert driver, whenever driving with close spacing, the tiny changes get
amplified. That's the origin of
traffic waves. The usual solution: preserve a large space
ahead of your car. If you have a large space ahead of you, you won't need
respond to speed-changes in the traffic ahead, even if those speed
changes are quite large. When
"noise" approaches you, it gets damped out rather than amplified. Cars
behind you drive
smoothly. -billb ] When
moving in waves, a significant part
of the jamming feedback is caused by seeing brakelights ahead of you, well
in excess of the actual decceleration of the vehicles themselves. You can
see waves starting on account of the injudicious use of brakes by "nervous
nellies", who aren't really slowing down, but feel a need to apply their
brakes anyway, causing everyone behind them to do the same, regardless of
whether they need to or not.

Consider looking into the partial differential equations behind this.
You have qualitatively nailed the phenomena which can be quantified. Two equations are necessary to model flow:
Conservation equation: Cars entering a control volume = Cars leaving + change in density w/in control volume (accumulation/depletion)
Constituative equation which relates the velocity of cars to the density of cars. In liquid fluid dynamics the density is constant and velocit is related to pressure. In traffic flow the velocity depends on traffic density. The simpliest way to model it is velocity = (K/density). Open road, low density == driver free to go fast. Traffic dense driver wants to slow down.
Combined and taken to the limits these equations create a partial differntial equation which gives you the wave behavior you describe in a traffic jam.
See the PDE text by Richard Haberman for more information.

For some reason I can't comment on the traffic jam part of your site so I'll do it here.
I invite you to come over to Amsterdam and try your cute little theory here, just to see how long you last.
'Aggressive drivers' passing you are how we all drive here. So you'd be here on the highway in a traffic jam with your huge open space and the people behind you will be annoyed by the fact that that space is there. The people on the other lane will cut in front of you so they can drive on for a bit, making the lane next to you fast than yours, so the people behind you will pass you through that lane and everyone will be fast than you.

Nice HP, really! I have an explanation of the following "phenom":
Quote: Sometimes during the night I hear music just faintly and when I get out of bed the music usually stops. One evening my son awakened to the music and asked me where it was coming from and neither one of us could find it and it once again just suddenly stopped. The music is not of this generation it is more of maybe the 30's or 40's. Another strange thing I hear at night is a low humming or a low voice talking like someone sending a radio signal somewhere on a submarine. I cannot make out what they are saying.

Had the same thing. Came out of an uncleaned air ionizer. An electrician told me, it?s possible to receive faint radio signals this way, because of semi-conductive properties of the collected dust along with some moisture of the air + dc can make this work very much like the crystal detector radio. The stopping of the sound is just the changing of your perception after standing up, imho. The old style music maybe due to some nowadays' station playing classics, too.

horizontally infront of our eyes. The next thing I knew I was on the
ground in the dark (the power on her street had gone out) and I looked up
to see my friend running and screaming towards her house. I was not hurt;
I fell to the ground as a reaction to the extremely loud explosion. We

I'm going into my third year as ab engineering
student in audio electronics. Your section describing how transistors
"really work" was a GREAT help to me. I thought I was the only one who
wanted to understand how a transistor really functions. All of my
electronics professors skipped honest explanation and made statements like
"I'll just give you the equations" and drew up different biases on the
board. I would admit to my classmates later that I didn't know how a
transistor ACTUALLY worked and would look at me like I was crazy. Now I
realize they probably are just a library of equations thats afraid to
admit their ignorance as well! Anyway, I just decided to search for
"understanding the transistor" on Google one day at work (at Altec Lansing
ironically) and here I am. Just wanted to say thanks for the help and its
glad to see there are people like me out there.

Bill, your "hovercraft" device is really called an airpad. When I worked at Otis Elevator in 1973, this device was the intellectual basis of the products of the company's Transporation Technology Division in Denver.

Otis Japan still builds transit products based around these devices.

The traffic waves analysis is excellent, and confirmed by a lot of current
research. Any of the detractors of this theory should do a search for "traffic
Indeed research shows that people who drive a lot, like taxi and truck
drivers, learn to instinctively swallow traffic shock waves by accelerating
and braking smoothly.
Detractors have argued that slowing down and leaving space ahead of you won't
solve anything because it will cause a jam behind you. However the point is
that smoothly flowing traffic has a greater flow rate than stop-start traffic.
So yes, if you brake suddently to leave a huge gap in front of you, you'll
probably cause your own shock wave behind you. However if you slow down
smoothly before the jam, you'll cause the people behind you to slow down
smoothly as well. And smoother traffic flows much better than stop-start
traffic, even if it's maximum speed is lower than in the stop-start

I hope you will get to read this Bill B.
Your FAQ inspired to me to create my own website. I had noticed that there is little or no info on the web about Mental Arithmetics, so I thought I would write something about that.
As I was wondering about addition, I noticed some things. Firstly, if I ask you to perform a simple sum like 25+46 , you will most likely start from the left hand end, add it, and adjust the first digit later. The same thing might be true for 3 digit and even 4 digit numbers.
But as the numbers get longer, we need to work from the right hand end, because constantly going back to adjust the numbers is just too much. But why should we do it that way in the first place? It's because we THINK about numbers from the left hand end. Which leads me to my revolutionary idea...
THINK ABOUT NUMBERS FROM THE RIGHT HAND END.
For example 53 217 - seven ten two hundred three fifty housand. I believe that if we thought about numbers from the right hand end, we could add awfully long sums very easily, as easily as adding 213 + 552 for example (you add that one from the left end, right?).
Since you (Bill B., or maybe others of you reading this) enjoy experimenting with weird stuff, I hope you will join me and try THINKING of numbers from the right hand end in normal life.

I like your traffic jam analysis. I had made the observation years ago in LA that the problems in heavy traffic congestion are analagous to problems in hydraulics. However I don't necessarily agree with your solutions; slowing down to create a large space which will eventually 'swallow' cars compressed together in a wave only creates another wave behind you, usually. The cars which would have normally occupied that space now have to occupy another space. Where would that be? Certainly not by the side of the road. They'll be in traffic somewhere behind you, being compressed from behind them by other cars. Presto, another 'standing wave'. Then there are the drivers who see the vast stretch of roadway in front of you as an opportunity to cut 2.8 seconds from their commute.
Better to eliminate cars altogether and build a truly world - class mass transportation system. We have the skills and means. We're just lacking the motive. But with gas crossing the $3/gal threshold it's getting nearer. I hope.

ON THE POSSIBILITY THAT KNOWN PHENOMENA REGARDING THE ELECTROMAGNETIC NEARFIELD REGION CONTAINS A BLATANT VIOLATION OF FUNDAMENTAL LAWS OF PHYSICS (a-vectFE.html)
William J. Beaty 8/28/99
"In donut-inductors, the magnetic field-lines from each turn of wire extend over to the area enclosed by the next turn of wire, and as a result the magnetic field connects in a circle, and no field extends past the surface of the donut... The question arises: how does the magnetic field inside the donut-inductor create a current in the secondary coil if no magnetic flux comes anywhere near the secondary coil? Electronics students always ask this question"
It is true that the magnetic field enclosed by the wire windings in the interior of the toroid does not extend passed the wire coils, but there is a perfectly functioning external magnetic field counter part in the air surrounding the toroid core. It is this field which produces all the induction effects wondered about in the beginning of the article.
Just imagine the very basic schematic of the magnetic field along a single wire with a current passing through it: it is in the form of a sheath of concentric magnetic rings wrapping around the wire - remember the Right Hand Rule. With these rings there is no overt 'N' or 'S' pole, but rathter simply a indication of direction of flow that deflects a compass needle tangent to the axis.
To form an electro-magnet, wire is wrapped in a tight spiral (rings) around an axis (generally a straight metal core). The magnetic fields generated around this column of wire rings 'join' together (as mentioned in the quote above) forming loops of magnetic lines of force parallel to the axis enclosing the wires, with the complete magnetic field taking on the classic toroidal shape with the 'N' and 'S' magnetic poles simply being where the flow of the lines converge at the ends. Similar to the Earth's magnetic field the internal field through the core is denser than the external field and the direction of 'flow' is opposite to each other.
When you wind a circular doughnut core you are simply switching geometries, with the electrical windings now taking on the toroidal shape and the magnetic lines forming concentric rings both internally and externally to the core - at right angles to the axis through the doughnut hole. To envision it just imagine all the fields as they exist around the electromagnet and then in your mind slowly bend the magnet into a loop and you'll see the geometries change shape with the internal and external fields becoming separated as they form into their own complete, but opposite flowing, individually closed magnetic rings. Because the magnetic fields in this case are closed rings with the toroidal axis at their center, just like the field around a single wire there are no poles. Since their creation is due to the combined result of the magnetic effects of the current flow along the wire windings there has to be an external field as well as an internal field. There is no way to get around this using electricity to generate the magnetic fields. If you want a magnetic toroid with only an internal field you have to use permanent magnets.
There is nothing mystical or magical going on here,
[ Actually, there is. Drs. Bohm and Aharonov
looked at Maxwell's equations, but unlike all others, actually could SEE.
Is the "vector potential" merely a mathematical fiction as everyone knows?
Or is it a genuine field, like an e-field? The truth was revealed by electrons
diffracting on two sides of a micro-thin inductor. The "A-field"
surrounding a magnetized iron ring is a very bizarre thing. Large
currents are induced in metal circuits wrapped through closed iron cores,
magnetic fields touch the
metal circuits at all. "Flux cutting" doesn't explain induction. And
bizarre, this stuff was totally ignored for almost a century. For those
who got a
creepy feeling when seeing a current induced in a large copper hoop
surrounding a totally shielded iron ring-core ...YOU WERE RIGHT. Your
intuitive bells were ringing.
Bohm and Aharonov paid attention to theirs. The strangest of
science is hidden in plain sight right under everybody's nose. We must
be very careful to avoid telling ourselves "there's nothing magic here."
We do that to comfort ourselves and reduce our "cognitive
dissonance" so the world seems understandable.
Scientists in pursuit of discovery must do the exact opposite: PURSUE the
horrible feeling where you realize that you know nothing, and the rug is
pulled out from under your entire grasp of simple physics. Some
scientists utterly loathe such things. I suspect that this habit of
loathing has killed their creativity. To remain creative we must beware
of sneering to ourselves "millions of people have already investigated
this topic." Ah, but what if each of those people had the same false
preconceptions and blindness, and every one of them ignores their
intuition ...but YOU DON'T? Go search google for "Bohm-Aharonov
effect" or perhaps "Aharonov-Bohm".
Of course this has no bearing on whether my weird
feeling about Maxwell's equations is true. Maybe I'm
just getting some backwards-time spillover from the Bohm-Aharonov
discovery. Perhaps I'm suspecting that something big IS hidden there, but
in reality something big WAS hidden there. -billb]
basic elementary stuff. The complications seem to arise because we are all
familiar with the way electromagnets are wound around segments of 'open'
straight cores with their resulting toroidal electromagnetic fields with
'N' and 'S' poles, and we forget to make the necessary adjustments for the
change in geometries when we think about windings on closed toroidal
cores. Also just like the confusion involving the various terms and
meanings of terms relating to electricity that Bill has done such a great
job explaining, there is great confusion regarding magnetic 'poles'. They
are simply the result of geometries, and should really just be thought of

Recently, having foud your site at work, I have been looking into the realm of amateur science, and with particular interest at the IR GOGGLES, some of which me and my friend made. We work with thermal imagers on a regualr basis and were intruigued (sp?).
We've made some, and WOW! Because the Uk weather is less sunny we're using 3 layers of lee's congo blue, and a sheet of UV filter for good measure. Lee do their own IR, which at some point soon I will be testing. I'm also trying to get hold of some black IR LEDs, and attach them to the helmet. I will try and get pictures of me wearing this somewhere if anyone is interested.
I've also looked, and found some other filters that may work, ad give better IR transmissivity.
Thankyou for inspiring me to try some science of my own

I am a non-professional cosmologist whose study has convinced himself of the existence of an energy medium which pervades all of space, and which provides the substance from which Free Energy machines should be able to obtain their "free energy", without magic.
It all started when I decided that an Expanding Universe was nonsense and devised a means by which the cosmological redshift (CRS) could be obtained in a static universe. The means rests on the truth of the statement "If there is a medium in space that supports electro-magnetic waves and if that medium is effectively increasing in density at a constant rate, then we would have a CRS that is a function of that rate-of-change and of the distance traveled by the electro-magnetic wave.".
Further study led me to accept the actuality of this medium (which I call aether, for convenience) and determine that it permeates all of space, from within the atom to inter-galactic, and has as one of its characteristics an intrinsic negativeness (a new concept).
Consider, now, the parallel plates of T. T. Thomsend's device surrounded by this negative aether and charged to (say) 20,000 volts and located in a vacuum. The positive plate of the device would be drawn in a direction perpendicular to that plate. No gravity involved!
I would be delighted to find a serious person who has an adequate education who could look at my cosmological model (which violates Conventional Wisdom) and appreciate where it is that I am headed and perhaps flesh out the scheme somewhat in directions that I haven't pursued.
For those Free Energy researchers, I am convinced that my aether is actually negative energy, that energy which is released by the stars of the galaxies of our universe and which is eventually recycled into new galaxies with an efficiency of 100%! (another new concept) As energy it surrounds us and permeates the atoms of our bodies and should be accessible, somehow. The most obvious grip we have on it is via the permanent magnets that we have, many of which seem to truly be permanent! Consider a solenoid with a DC current flowing in its turns. For all practical purposes it is indistinguishable from a PM. Now, consider the effect of this current flow on the negative energy surrounding the coil. ??? Bearden seems to be onto a setup which could have a COP>1 and if optimized might be workable. Sweet may have had a grip onto a workable device but was too secretive to leave adequate clues. These devices, and apparently many others, all use PM's. I have some ideas on this but have run out of money so can't continue my benchtop research, much as I'd like to. My cosmological research is with a pencil, so far, so that's where my attention is focused.

Hi all , I head the Physics Dept.in Gov. High School Atiela and run an
N.G.O. for the promotion of basic Edu and Child- centred
Dev.(www.geocities.com/orescameroon).Affordable solar furnaces
constructed if possible using local materials can transform the lives of
my people. In Bamenda where I live energy from petroleum and electricity,
being monopolies (in the hands of one corporation) are used as tools to
overtax the people. The people are getting poorer and poorer by the day
and are resorting more and more to wood for fuel.Deforestation and its
consequencies are already visible . The paradox is sunshine is abondant
.In my own little way I tried to construct a solar cooker which could be
made out of local materials for the cost to be down to the level of the
masses.It was challenging but very interesting.Mine didn't work because I
had difficulties with the mirror. I wanted to try polished steel for the
mirror;I coudn't lay hands on it. I wanted to use pieces of plane
mirrors;I had difficulties mounting them. I tried the silvered side of
parcelling paper. The result was impressive but fell short of being
reliable.(it wrinkles easily). I have not given up yet.We have adopted
the solar cooker as our project for next year in the Physics
Dept.Meantime if it is possible for anyone out there to construct an
effective and reliable solar cooker to cost say, $80 to $100 my
organisation can purchase them and make them available to the
masses.Thanks Julius shenga Email: jshenga yahoo

In your How Transistors Work article, you advocate the melting of lead

dangerous, as lead will evaporate, though slowly, and sulfur will form
hydrogen sulfide, another toxic gas. I can't tell whether this article is
part of your K-6 page or not, but either way there should be a safety
warning involving ventilation.

WoW! This website is really great for the imagniation, TOO bad not
everything in the website is true. Fix up the Bio section. The posting in
the bio section is absurd. The guy asks how can cells move.
[ No, I ask how paramecia can act like insects or
hamsters, yet without having a nervous system. Have you ever watched live
Paramecia before? They use cilia for navigation... how are the cilia
motors controlled? How are they even synchronized? Where is the
which determines paramecia behavior? These issues have nothing to do
with the subcellular "muscles" of the cytoskeleton. There's also a
question: what are paramecia's fast-acting muscles? Amoebic flow has
been explained (as I specifically mentioned in the article: it looks to
me like a big blind spot among researcher.) Paramecia perform motions on
of tens of milliseconds which obviously *don't* resemble the slow
cytoskeletal changes responsible for amoebic flow. How do paramecia do
it? (Perhaps their surface cilia are somehow used to change
the cell's shape rapidly, as well as being used to propel the animal

I really enjoyed "Spirituality? Or just intentionally triggered
psychoses?" at http://www.amasci.com/stuff.html. It is nice to see people
interested in pursuing a form of enlightenment that involves
strengthening, instead of attacking the ego. I particularly liked the
comparison of the Buddhist ego death to joining an ant colony.
The "hive mind" idea can be generalized if you take into account the
evidence that the average human brain is at least physically capable of
"telepathic" communication. If the class of neural activity commonly
referred to "subconscious" is in touch with this mechanism, then one
person's subconscious could hypothetically connect to others and form a
sort of network. This would provide a physical mechanism for phenomena
such as "astral travel" and the "collective unconscious". If this were
true, what would we expect to find in the World Wide Brain Web?
[Heh. Great minds
think alike. Those same ideas are EXACTLY what I realized
myself when I was writing the article (but I didn't transcribe it all from
paper, it's still in my notes.) I was led to the idea of a "telepathy
internet" by the claim made by psychics that separate animal species each
have a distinct "goddess" which humans can contact. If true, this might
same idea as termite or ant colonies having an emergent consciousness...
applied to non-colony critters like beetles, cats, cows, people. If we
humans are part of a telepathy-internet which connects all humans, then
of paranormal phenomena become physics-based, since "the net" might
usurp our perceptions to produce miracles which are nothing but
complicated mass hallucinations. If "net viruses" can mess with the
images on your "web cam," then perhaps you shouldn't always trust your
eyes. The mental-internet might even be doing this constantly, moment by
moment, since Western
mankind lives in a concensus reality. As kids, we learn from our parents
how to see concensus-reality. This is extremely useful for survival in
society, but also it blinds us, and we cannot see past the
mental filters without lots of effort. These "filters" which
create our perceived world... they might be learned,
but then again they might be "installed" automatically via the
telepathy-internet, with little conventional learning involved.
In addition, a "telepathy internet" becomes a wilderness full of viruses
with a scale of power from simple infectious memes, all the way to
genuine "gods" powerful enough to manipulate huge populations. Also,
wouldn't each kind of animal brain have its own telepathy-internet? There
might be a "goddess of the ants" and one for the hamsters, etc., mass
intelligences with which
humans could communicate. Individual birds and deer might lack much
intelligence, but the colony-minds such as the "bluejay goddess" or the
"white-tail deer goddess" might
be far more intelligent than any human. And then Native American
Religion would be closer to physics than our own physics is
PS, The movie "The Matrix" is filled with Carlos Castaneda references...
or perhaps both the Carlos Castaneda books and the movie are full of
references to this telepathy-internet idea: The Matrix. -billb]
there would be very few people capable of consciously manipulating this
realm, it would probably be saturated with the psychic equivalent of
viruses and ad-ware. Now add Richard Dawkin's "memetics" to this mix, and
you get the possible existence of whole ecosystems of brain parasites
living and reproducing in the WWBW. Since their environment is a network
of complex organic computers, it wouldn't be surprising if some of them
developed a form of rudimentary intelligence. They could probably
manipulate a host animal by making it consciously aware of selected
thoughts and use fear to discourage any line of thought that would lead to
their discovery. If infants are consciously telepathic, they could be
scared into ?correct? thought patterns with threats that appear to be
coming from the parents that they rely on for survival. [But suppose that all of us were manipulated by the
mind-parasites in that way. What do you recall during childhood
that could have been the side effect of living memes tearing pieces out
of your mind? How about...
CHILDHOOD NIGHTMARES? "Night terrors?" Maybe parents are right
when they say that kids have to be good, otherwise the boogie man
will come to get them. The boogie man gets you anyway, and rapes your
brain. The result is that, against your will, you turn into a grown-up.

the mother?s body for nutrients. Disobedient fetus? Oops! Looks like

Up to now I have not obtained an explanation intelligible to myself for
the following phenomenon and practice of home electricians who are
self-taught small time electrical contractors.
In my place the
current is a.c. 220 volts. I have appliances which run on a.c. 110 volts.
So that I would have outlets in the house giving 110 volts a.c., the
electricians I hired would use only one wire from the two wires from
source of 220 volts a.c., and the other wire in the mains outlets is not
linked to the source but connected to any exposed reinforcement steel bar
of any concrete component -- out of the way and out of sight of course,
for example the concrete posts supporting the gate of my property
So, now I have a 110 volts a.c., with one wire from the
a.c. source and one wire from any metal component like as I described
above, or even from a steel water pipe buried in the soil or -- and don't
think that I am fooling you -- even to the steel frame of the box housing
the fuses or trip interrupters where the source from outside is
distributed to various parts of the house.
But the power is
limited because when I use two appliances of this kind of a 110 volts
a.c., they will both work slower, for example several incandescent bulbs
of 110 volts.
What is the explanation for this phenomenon and
I have not read about this practice anywhere; but from
a book written by a guy who is a home building contractor, he mentions
that a 110 volts a.c. can be obtained by using one wire from the 220 a.c.
source and the other wire from the neutral wire from the same source:
namely, the 220 volts a.c. is supposed to have a third wire, between the
two, so that one wire is 110 volts above this neutral wire and the other
is 110 volts below this neutral wire.
Now, I want to tell you
this: in my first house the local electricity provider allowed home owners
the option to have both the regular 220 a.c. and also if requested the 110
But now this provider does not give this option
anymore -- and that is why self-taught electricians resort to thetrick I
described above. Why doesn't the electricity provider allow this option
anymore? Maybe to help businesses selling step-down transformers --
Well, what do you say about all these observations I have

I was sent a website by some IPO investment outfit about a device that
somehow increases efficiency in the home just by plugging the unit intoa
wall socket. Suspiciously the website does not offer prices. Anyone
heard of this "MEGAPOWERSAVER" (www.megapowersavercom) Is this possible
or likely?? Mr. Beaty, your articles have really got me thinking
differently about electricity. Thanks!
Sites selling 'weird technology' are usually scams,
although some are honest. The site you mention sells a device which they
don't explain. Which appliances are supposed to become "less efficient"
over time? They don't say. And how can a plug-in product have any
effect on them? Try searching
google for info. As for home appliances, brushless induction motors
in appliances never change (except their bearings might need grease after
decades.) Electric heaters are always 100% efficient. Stereos, TVs,
computers, etc., don't draw more power with age. So where is the problem
that their product is supposed to solve.
I know of only one possibility: the "green plug" energy saving
device developed by Frank Nola of NASA. This device is
connected in series with AC motors such as refrigerators. "Nola" devices
are real, and they save some energy by turning down the voltage after an
motor has started up (since then the motor needs far less torque to keep
going.) But "green plug" devices MUST be wired in series with the motor,
and the device you mention is connected in parallel. -billb]

I have approached the transport dept of NZ asking if they have data on what causes congestion. And guess what? they aint got anything.
I have studied the cause, like you have, and thought it was time to make changes. Changes to the way drivers use the road, and changes to the information on the signs around our motorways.
I was hoping that you might want to help me create the worlds first standardized driving and traffic system.
My thinking is, that because traffic is not regulated, there are jams. If all drivers (a little like formula 1) took off at the same time, and kept the right distane, there woudl be far less accidents and subsequent congestion.
Imagine the joy of having ALL cars traveling 4 lengths behind, not necking, and keeping in fast, slow or merging lanes. I think traffic owuld flow much better, BUT, you have asian drivers, islanders, middle aged and teen whites. Many of whom drive slow, cannot pace for space, and have no idea how to elp smooth traffic out.
So, my thought was to lillicit assitance from you if you have the time, so that we can both hit the MOT at the same time.
The reason I ask for your assistance is that you are an engineer, therefore in the the eyes of the experts, must be more intelligent than a layman like me.
If you have the time and inclination, I would like to hear back from you.

What if you applied the principles of fluid dynamics and materials science to traffic? (See http://www.amasci.com/amateur/traffic/traffic1.html)
When the particles (cars) in the fluid (traffic) are moving at a higher speed, they are under less pressure. When they are moving at a lower speed, they are under more pressure. Higher pressure causes more stress. Repeated cycles of high pressure cause fatigue until the cracking point.

Your theory is nice and all. But it is lacking a real solution.
Slowing down to achieve a greater average speed does work, but to what
extent. We millions of cars entering and exiting our highways everyday.
Highways that have real, defined capacities. There is NO getting around
maximum capacities of these highways. Once these capacities are
approached, reached or exceeded traffic slows or halts. Simple as that,
and it takes hours to recover.
which brings me to my point.
Your theory accounts for alleviating traffic pressures, but does not look
to the cause of the problem. THERE ARE TOO MANY CARS IN THE UNITED
STATES. To reduce traffic we should develop mass transit systems, not
