The Powerlite C core that is used in the MEG has a loss of between
15mW to 500 mW/ cubic cM depending on the flux density at 20kHz.

Not bad for the traditional MEG frequency (45kHz oscillator, one pulse
for each half cycle out= about 22.5kHz operating frequency) 20 Khz is
traditional also for the operation of a typical pwm inverter or switch
mode power supply. I believe you are absolutely right in wondering if
there are 2 different things going on.

Try thinking only of increasing the permeablity of a section of the
MEG core at the place where the input coils are on the present model.
We would need to be able to do this with similar input circuitry.
Suppose we could do this with no external flux being generated in the
system. We would then be dealing only with the flux of the magnet. It
would shuttle to the opposite side of the MEG and our well explained
theory would be reality. There would be no need for specially
conditioned resistors, or of not-so-convincing oscilloscope power
analysis. The only power out would be from the shuttled flux of the
magnet. And the faster we could shuttle the flux, the greater the
output power would be.

So, back to this writer's initial thesis: I believe he MEG WILL work
if we can use metalurgy or some other exotic property of materials
magic to change the permeability of the core without introducting
external flux. I really believe it goes beyond a close winding or
other traditional transformer building technique. It strikes me also
that frequency tuning would be unnecessary using this yet-to-be
discovered technique. Well, I can dream, can't I?

Best to everybody-except you bastards in the oil industry--

Well said... the proper meg resembles a well tuned antenna more than anything else I've seen... keeping the flux where it belongs is essential... both in the...
