Dear J.K.,
Consider the flaw in
your "resolution". You have assumed that, no matter what voltage you
put in, in a switching mode, just the switching (making and breaking
contact) will use up all the energy.
Were that true, even
no conventional switching power supply would work, of the hundreds that
are on the market. So that notion -- which is really that switching
itself will dissipate all the potential energy -- is already falsified
by untold thousands of experiments and working devices. Nonetheless,
that is a good thing, to "go at" a notion or idea, to try to see if it
stands up or if you can find a flaw in it. If the flaw is there, the
notion or idea has been "folded".
However, let me
encourage you to keep thinking and keep that inquiring mind, open to new
notions and concepts, but also examining them with the best
understanding you have. The important thing is to keep BOTH the
inquiring and open mind, AND the skeptical, honest examination.
On the particular
problem, you might like to think this way. It does not cost anything to
add voltage alone, so long as the electrons do not move in the conductor
to which the voltage is added. The electrons do take a finite bit of
time to get going, but unfortunately in copper it's very, very short --
something like 10 -16 to 10-22 seconds, depending on some of the
estimates one makes in computing it. Check any good book on
electron relaxation time.
That is what the time it takes the electrons to really get moving is
called (loose explanation, deliberately not the prosaic and rigorous
definition!).
However, there are
many conducting and semiconducting materials where this relaxation time
is far longer. Alloys can be made --- with difficulty, one being about
2% Fe alloyed into Al --- which have an electron relaxation time of
about a millisecond. That's called a 'degenerate semiconductor'.
Anyway, one millisecond of "frozen electrons" in the potential-receiving
wire gives you plenty of time to connect the voltage and STATICALLY
potentialize all the temporarily frozen electrons in the special
conductors. Since the potential flows at nearly the speed of light onto
a wire or conductor, you can potentialize quite a bit of
temporarily-frozen Drude electrons that way, and still switch away the
voltage source, leaving the "static potentialization" still on that wire
or conductor.
Then in the
now-potentialized circuit, the electrons suddenly wake up and their
frozen state melts, and they begin to move as current. At that moment,
dissipation of some of that potential energy begins in the circuit, and
the circuit is doing work and dissipating energy in its losses. Not
until the current moves, is ANY energy being dissipated in the
potentialized wire circuit, even though one has freely changed the
potential energy of the wire (and therefore of the circuit). The amount
of excess free energy you have collected in that circuit is given by Vq,
where q is the amount of charge in the potentialized temporarily frozen
electrons, and V is the magnitude of the potentialization applied. That
gives you the excess free potential energy in joules. (There is a well
known gauge freedom principle in quantum field theory and
electrodynamics that guarantees that pure change of potential alone,
requires no work. Electrodynamicists use that principle all the time).
So if you withdraw the
"potential source" used to potentialize the temporarily frozen charges,
while they are still frozen but now potentialized, and simultaneously
connect up that statically charged conductor as the high potential line
in a closed current loop circuit with the load (put a one-way diode in
the back-emf region of the circuit, and a capacitor in there helps
also), voila! You get a free discharge of energy in the load, which can
be a lamp or common resistor.
In real life, one has
to pay a little bit for switching, but that can be made very, very
efficient and low cost.
Everything in the
above gedankenexperiment is already well known in electrodynamics,
quantum field theory, and physics.
There are of course
many refinements on that crude circuit explained. A real circuit fellow
can give you lots of improvements, so long as the basic principles are
maintained.
So let me encourage
you to keep studying and questioning. You have just started physics.
It is a very, very comprehensive subject, and has a very great number of
facets, odd corners, and discoveries just sitting on the shelf. It also
has lots of individually discovered things in one area, that are little
known or unknown in other areas. So one fascinating thing is to try to
put together some of these presently rather "disjointed individual
things" into a system to see what happens.
Any number of new
breakthroughs are sitting there in physics, on the shelf, just waiting
to be put together and made to work in a system by sharp young students
"thinking outside the box" a bit, to use a present buzz word phrase.
Best wishes,
Tom Bearden
Subject: "The Final Secret
of Free Energy"... flawed?
Date: Tue, 27 Nov 2001 13:40:10 +1100
I've looked through the
theory presented in "The Final Secret of Free Energy". After reading
through it, I think the idea is more or less like this:
Position the two ends of a
wire (for example) near the terminals of a source of electric potential
- such as a battery or capacitor. This pushes / pulls the electrons in
the wire towards one end. Now, this wire is quickly moved and connected
to a circuit, where it releases a current. The wire is moved back to
the source, and the process is repeated.
At first I only saw
engineering difficulties. I really wanted to believe that the theory
worked, but the energy has to be coming from somewhere, and the claim
that the energy was coming from the vacuum didn't satisfy me. After a
few hours, it came to me. After all those years you spent on this idea,
it seems almost cruel for me, a 17 year old physics student, to have to
tell you this!
When the ends of the wire
become charged due to the source, they becomes attracted to the source.
To move the wire away and connect it to another circuit would require...
energy.
Overall, the theory only
appears to give a method of converting kinetic energy into electrical
energy - a task for which we already have generators, which do a very
good job, too.
I really wish the theory did
work out... but I cannot see how it does so.
