"This should be contrasted with a vacuum

strength of the gap falls to a minimum level of a
few hundred volts in the glow discharge region of
0.110 torr (13.3133.2 pascals), recovering to
around 30 kV/cm at atmospheric pressure."

Knowing that aircraft electronics is pressurized
for 10,000 meters, I think you might have more
like 50 km to insulate on the low end. The
consequences of a pinhole in the insulation are
that the conductor sputters away. That's what
happened to the failed shuttle experiment.

You don't get as much effect out of spacing as
you would think. It's the effect of more material in parallel.

If this were the case for Boeing, their aircraft
would never get off the ground.
In my experience as an engineer, my designs have
always worked about as expected. In any case,
the consequences of not doing something really
big in the light of energy problems are really
awful to consider. Even if power sats are
recognized as a way out of the carbon and energy
problems there are going to be some dire times
before they can be brought on line.
