Last time I did a boom with a capacitor, it broke the "broomhandle" AND
the capacitor terminal leaving a nice leak hole...
And that was ONLY 300V, but 10uF.
I think the resistor way is safer.


ok... what would be a good resistor... I figure, 1 megohm or so should
be just about right, RC of these 1 uF caps would be about 1
second. Discharging most of about 40 joules in a couple of seconds.

Well, let's see. P = 22 kV squared / 1E6 = 484 Watts.
Well, that isn't so amazing, but I don't know where you will
find a 1 Meg Ohm resistor with a 500 W rating and a 22 KV
voltage rating.
