Dan -

How did you determine that the solid state Tesla coil (SSTC) outperformed
the spark gap Tesla coil (SPTC) in power vs power? What tests did you use?

It was my understanding that from past coiler tests that the SPTC
outperformed the SSTC in energy vs energy or overall efficiency.

Keep in mind that power is equal to volts times amps and is an instantaneous
condition. Power is equal to energy/time. With a fixed time period the power
and energy would be equivalent.
