Dan, I don't think the 30psi-or-so necessary would elevate the voltage that
much... have to look at the tables for dielectric constant of air at
different pressures to make sure.

30 psig is three times the pressure. So the Mean Free Path would be
1/3 as long. So the arc voltage would be three times as high. Unless
my memory has failed me.
