Malcolm -

I agree the TC voltage is one of the dependencies when talking about spark
length. However, this problem is to find the TC energy in and the energy out
to determine the overall efficiency. The TC voltages are another problem.

When you are talking spark length, voltage is most certainly one of
the dependencies. 1J at a voltage of 1V is not going to produce a
terribly long spark. Neither for that matter is 1MJ. One of the expts
I suggested to Marco should help in determining just how important
voltage is beside the other factors, particularly in repetitive
operation.
      A low capacitance (read "small") coil pumped with 1J can be made
to produce the same voltage and single shot sparklength as a much
larger, higher capacitance coil fed with 10J.
