I have just been told by someone in the lab that what we actually have
built is nearly a replica of something called the Searl Levi-Disk. It
is exceedingly difficult to get any sound and reliable information from
anyone on this device !
I appreciate the email from Mr Sterniman; it seems well-reasoned and I
am replying soon when I have attempted to set the math of it straight in
my own terms.
I am unused to newsgroups and their etiquette, and I hope regular
readers will forgive the inevitable confusion of a novitiate ?
It seems that we can summarise as follows:
-----------------------------------------
When the flux of an N-pole cuts the flux of an S-pole such that the
tensor fields experience the maximum tendency to repel (pi/2), we create
an electric field in whatever gap exists between the sources of the
flux.
We will also, a priori, because of the fact that the disk does not
rotate its magnets in concentricity with those on the outer wall, be
setting up a variation of transfer of angular momentum of the
electromagnetic field associated with the electric field cutting flux
all the time the disk is turning.
This eccentricity has an interesting locus and traces out a cylindrical
path of wall-thickness equal to twice the original eccentricity of the
magnet ring on the disk (when stationary).
We are going to run the device again soon, using a remote spring balance
to ascertain the apparent mass loss so that there is no chance of an
interaction between the pan balance and the device.
Also, in answer to many queries, "No, it's not electromagnetic
interference from the motor which caused the strange effects."
Running the motor free is fine. It came from a vacuum pump which had
been running in the lab for ages !
Anyway, after thirty years in physics, I've yet to encounter a 50Hz
mains induction motor that could dim-out flu-tubes and blow up LCD's.
More news when we have it.
Please keep ideas flowing in - this device threatens to prevent me from
building the HV/HF switches which we are supposed to be producing !!!!!
