Re: Addendum-DC Tesla
Richard,
I have noted an interesting phenomenon that might be
related to the field emission rectification......

On a small coil setup operated single shot (as much for safety as
anything else), I've found some rectification going on (at least
that's how it seems). If you hold a metal rod (insulated shoes)
near enough to the terminal to attract a fat stream of whiskers that
end in a point at the screwdriver, you can get very definite and
heavy jolts (definitely not AC). Holding the rod close enough to
attract a single bright discharge channel kills this effect
completely (not all the time but mostly). This sounds a bit like your
experiment with the Maxwell cap. I'd be very surprised if this didn't
charge an isolated capacitance to very high voltages.
For what it's worth,
