Re: [TCML] Prepare a Hot Dog (on TV)

Not only that, but the impedance of a sausage is very poorly matched to the
tesla coil, energy transfer is likely less than 10% :-)

Perhaps you can get a significant amount of heating from bombardment,
similar to how you can melt a breakout point, but not the thin wire in your
secondary.
