I don't want to be a wet blanket, but I must agree with Bob on this point.
The spark-excited oscillator has been with us for over a century, and every
imaginable static gap scheme has already been tried by somebody, somewhere.
Time is the test of such things, and those that work best endure, while
impractical ideas vanish into obscurity (until revived decades later, by
some Tesla coil nut!). Don't let this put you off of experimenting. It
sure hasn't stopped me.
