Yes, they are touching. And yes, it is a capacitor. The hubcaps or toroid or sphere function as a large smooth surface for charge to accumulate. The other plate of the capacitor may be considered to be the Earth. The hubcaps here have a capacitance of a few tens of picoFarads, which may not sound like much, but at a few hundred kilovolts it represents a lot of energy storage. Combined with the low inductance of the air-core resonator, it makes a significant difference in the resonant frequency.
Thanks! Since yesterday I've blown another 4 IRFP250 mosfets, and 8 1n4744 Zeners, and a 2n7000 minimosfet. It's only about 18 dollars worth of parts; I probably could have consumed that much in beers and pizza, watching hockey on TV.
good thing your not jamming Coast to Coast anymore LMAO.

the ducting tops always remind me of the robot from the tv series lost in space.
question: are the two hub caps electricly seperate? or do they touch? i presume the latter, its just that everyone calls them capacitors..
thanks, another fab flame !!

Sort of. Except in these rooms, I'm all by myself, which is how I like it.
(Oh, and the coffee's a lot better.)
