Re: Duncan Cadd on Tesla Coils

Yeah, the shooter pic is a bit over the top ... particularly the graininess; I kind of expect a ransom note with it. Why don't you buy his idea that resonance plays the role of the VdG belt, and is what transports the tesla coil's charge up to the topload? Just curious, since the total voltage up there is proportional to the square root of the ration of the secondary capacitance to the primary capacitance, his explanation is an attractive fit with the specs of a VdG generator.

He shows that a Van de Graaf generator and Tesla coil operate on the same concept, but with the Tesla coil replacing the Van de Graaf's moving belt with a sinusoidal AC current pushing the charge up to the topload capacitor and the secondary serving as equipotential rings.

Just thought I'd share this if anyone is interested

He may show it but "it ain't so"! Very interesting site, particularly his home-made quenched gap. Having contemplated making one many times I see that he put about as much effort into it as I figured it would be. Fortunately I picked up a real WW1 surplus quenched gap which works really great on a small coil. Lot of good reading here although, even though I'm a shooter myself, I didn't care for the picture with the semiauto.
