Re: Superconductor Tesla Coil

Also of note: You can lower the resistance of your ordinary copper coils by 
a factor of ~4 by cooling them to LN2 temps. If one buit a LN2 container 
for the secondary, there would be no need to coat the coil. The LN2 is a 
very high breadown strength and very low loss insulator. This might be a 
good way of getting very high coupling k's and higher efficiencies with the 
standard 2 coil system.

Murphy was a lucky bastard.
