Ball lightning response
You must have made it back from Las Vegas. Congratulations again. I hope
your wife enjoys your Tesla hobby. How was the wedding? Did you come back
with any money?
Thanks for your response on ball lightning information.
I am currently building my first rotary spark gap. I am using a 1/4 H.P. DC
motor, 3/8" dia. Lexan wheel 10.0" in diameter. The fixed electrodes are
tungsten and the rotary electrodes are stainless steel cap nuts - like Mark
said he uses. How large of a fan do I need to cool this? I plan to build a
wooden box to sit over the top of it ( I will cover the top with flashing for
a strike shield) and I was going to mount a 100 cfm fan in one end and drill
some holes in the other end. Is this adequate?
My commercial capacitor should ship in a few days. Things are going to get
very exciting soon!
