RE: Low Impedance Negative Resistance Tesla Coils

Original poster: "Ken Jenkins" <thecompman@xxxxxxxxxxxx>

Just a Thought..
What if you used super conductive wire to build your Primary & Secondary
coils, Solenoid wound secondary close coupled. Then put the whole thing in
Liquid helium or nitrogen...
Wouldn't this give you a coil with virtually no resistance??
Like I said
Just a thought..

Regeneration requires the use of a power supply to overcome the real
loss so in terms of power spent you actually only gain a further
inefficiency. This is quite different to increasing the collecting
power of an antenna.
