The few turns of thick wire in all coils? Was that really the most 
efficient system that could be built? Hands up all those who believe 
Tesla hit 10MV. Are you suggesting that were that coil to be lossless 
(i.e. Q being infinite) the output voltage would have been infinite 
too?

Not sure. I think for his transmission system he would have been 
aiming for as close to CW as he could get.
