Wow!  Since all TC's have at least some stray resistance in the wiring of
the tank circuit, does this mean any Tesla Coil can never be more than
50% efficient?  It seems so if the same amount of energy delivered to the
tank capacitor is dissipated in the wiring.  Would someone correct me if
this is wrong, as I am a little confused by it.
