Default Speaking of I2R losses

Good work. Congratulations on doing some real experimenting and
thanks for reporting.
What do you attribute the losses in the cap to? Could it be contact
resistance between the plates and the rotor? Would it be possible to
substitute some commercial cap temporarily to compare?

Show me a 100% efficient cap first, then I will show you where to patent
it and sell it. You will then have the money to purchase my bridge in
the desert!

Of course, there must be lossless caps somewhere, huh? Because a cap
with no dielectric would suffer no losses (ignoring the resistance of
the plates to the inrush, exhaust of electrons), huh? So then, a cap
consisting of plates in a vacuum would have no dielectric and no loss.

Strange, I seem to still notice a loss in such a device when examined
mathematically. Perhaps the ether is serving as a dielectric?
