Capacitor / Coil displacement currents

[Jeg]

Hi everybody

Is there anyone out there who has experimented on this concept? I suspect that it has to do with Cook's coils and Ed's PMH. As Ed said, coils are wounded on brass or aluminum cores. Why is that? I believe that he used those cores for capacitor plates bringing it in resonance with coils as in the attached image.

Any comments?

Richard Feynman's lecture on the subject of non-ideal capacitors and inductors would be a good thing to read.

I guess that in this volume of the three is what you refer to.

Did you try any setup on this subject? I find it very interesting!

I have a design that I planned to use for brushless extraction from an ac homopolar generator that's based of the principle.  Thing is it's just a design for now.  Think it might actually work, time will tell?

At high frequencies one has to deal with it as a matter of fact.
