<< have been using capacitors off and on since I was 11 years of age (and
that was a long time ago) in "ham" radio, and at work building control
units for linear accelerators and electron beam pattern generators used
to make the patterns for integrated circuits. >>
if you like capacitors a 1994 popular science has an interesting blurb. they
have super capacitors now based on the observation that plate area of a
capacitor is related directly to it's power out put so instead of flat
capacitors (capacitors with flat plates) they are making pitted ones with
indenations that increase the surface area.
this could be helpful for electrets or work with t.t. brown anti-gravity
