Hi all, Gary,
Would you mind elaborating a bit about your pressurized spark gap? What
sort of container was it in, pressure, voltage, etc. I may never try it,
but it's interesting!

I think what you're suggesting is that losses from a vacuum-contained spark
gap will be lower because they can't loose energy due to emitted sound. The
losses from a spark gap occur in the forms of heat, light, and sound. I
would speculate that of these three, that the acoustic losses are the least
of them. The sound is just a by-product of the others.
More importantly, the resistive losses (which generate the heat and light)
are a function of the conductivity of the plasma. I have no personal
experience with plasmas in a vacuum but I have made measurements of gap
losses in air at higher and lower than ambient pressures, and have found
that losses are significantly lower in a pressurized gap.
