Where can I find info on this effect of max energy transfer? Are there
reported tests of people who
have designed and built capacitors? As well, is there a good source of
engineering details in resonance
designs and practices? I've had a chance to read and enjoy a book by
someone associated with the
International Tesla Society ( I'm sorry for forgetting the name). This
book, if I remember, is written
by...Resonance Research... or something.
Thanks in advance, Richard.
p.s. I imagine you are the one responsible for TCBOR since I see your
name many times. Hope to exchange good
ideas in the near future, possibly meet in person.
