Ernest Cullwick was one of the first people, back in 1957, to notice that
|
|
there is an unusual problem in trying analyze a rotating EM wave. There hasn't
|
|
been much formal work done on this subject since Cullwick's book (at least not
|
|
that we know about).
|
|
|
|
But, it's evident from the the discussion in this forum over the last few
|
|
days, that the mysterious properties of the circulating EM wave have not gone
|
|
completely un-noticed. Here's a few more things about it.

If you work out the metric for EM waves circulating in a cavity you get some
|
|
strange results. There is a preliminary discussion of this effect in the
|
|
article by Houshang Ardavan, 'Gravitational Waves from Electromagnetic Waves'
|
|
in the book "Classical General Relativity," edited by W.B. Bonner, I.N. Islam
|
|
and M.A.H. MacCollum (Cambridge Univ. Press, 1984).
|
|
|
|
It is something I have seen done. At the point in an annular cavity where the
|
|
phase velocity goes from less than c to greater than c, a term shows up in the
|
|
derived metric of the system that looks like a source term.
|
|
|
|
On the other hand you have assumed that the metric is source free in the EM
|
|
region of the cavity. So you get a solution which contradicts the hypothesis
|
|
that went into building the solution. You get something which is possibly
|
|
unphysical.
|
|
|
|
Now Einstein's equation and the associated geometry is pretty tricky and it is
|
|
easy to get unphysical solutions. The final arbiters of whether a solution is
|
|
satisfactory or not is physical reasonability and self consistancy (these are
|
|
almost the same thing).
|
|
|
|
The cavity problem seems very physically reasonable initially, but ends with a
|
|
self-consistancy problem which appears to be unphysical. Also, Cauchy's
|
|
theorem does not apply to this case since it becomes a mixed type problem
|
|
(elliptic and hyperbolic PDEs), so the Hawking singularity theorems don't a
|
|
priori apply.
|
|
|
|
It is something very interesting, but to publish it with out being scoffed at
|
|
would take a lot of work and possibly inventing some new math.

Next some comments by Dr Dennis Cravens in a report titled
|
|
|
|
"Electric Propulsion Study",
|
|
done for the Astronautics Laboratory at Edwards AFB. August 1990.
|
|
|
|
Dennis Cravens was formerly with SAIC Corp, and is now working with CETI in
|
|
development of cold fusion. Anyway, here's some things he says in the electric
|
|
propulsion report about the "peculiarities" of a rotating magnet:
|
|
------------------------------------------------------------------------------
|
|
ROTATION OF MAGNETS - There is a continuing debate in physics as to the
|
|
reality of the magnetic field. The prime question is whether the axial
|
|
magnetic field of a bar magnet rotates with the magnet or is stationary.
|
|
|
|
The Faraday homopolar generator dates back to the 1830s. DePalma, Tewari, and
|
|
others have attempted to utilize the Faraday generator to produce more power
|
|
than needed to run it. Most objective reviews of the work have, however,
|
|
failed to see such effects.
|
|
|
|
It is doubtful that these claims will be independently validated and even more
|
|
doubtful that they will lead directly to a propulsive system. However, the
|
|
work on homopolar generators as high current devices is reasonable and may be
|
|
useful for ground uses. The angular momentum complications seem to rule the
|
|
system out for any practical space applications.
|
|
------------------------------------------------------------------------------
|
|
SEARL EFFECT - The Searl Effect is a separate issue from homopolar generator
|
|
above. Searl has claimed to produce disk levitation by rapidly rotating
|
|
magnets. There have been claims of anti-gravity, high electric fields,
|
|
perpetual motion, inertial loss, and gas ionization. All these claims come
|
|
from Searl or those supportive of his work and no outside witnesses are
|
|
available. Searl has not supplied any technical data or specifics of the
|
|
operation in any easily referenced source. It is not recommended that his work
|
|
be experimentally followed by the USAF. It is worth noting however, that a
|
|
rotating magnet does have some definite theorectical peculiarities.
|
|
|
|
Through the years there have been many interesting developments concerning the
|
|
Faraday Homopolar generator. DePalma has claimed to get more energy out than
|
|
is supplied to the the generator. None of the claims seem to withstand
|
|
careful examination and no machine has ever been made self driving. The
|
|
underlying reason that such claims continue to surface is that rotating
|
|
magnetic fields are extremely difficult to handle within existing theories.
|
|
|
|
This is because for a rotating frame there is a distance (removed from the
|
|
axis) which is travelling at velocities greater than c. Although the distance
|
|
is not withing any real physical object, it's existence within the
|
|
mathematical development greatly complicates any calculations.
