So I bought this capacitor a while back and kinda forgot about it. The other night I took it out of it’s crate and put it on a dolly. It’s freaking heavy at 86 kg (190 lbs). It’s rated at 16 kV, 390 uF…. storing 49.92 kJ (kilojoules).
Now we have a power supply capable of charging this thing.
Here is what I’m thinking: 16 kV is enough potential to drive a fusor grid. So basically charge this thing up and release an very high current 16kV pulse into the fusor grid.
This capacitor is probably the most dangerous piece of equipment I own. It scares the shit out of me.

Right! Measure twice cut once. _Always_ check the terminals before touching. Household 117AC doesn’t physically damage your body (it can cause you to forget to breath or interrupt the heart rhythm) but these voltages you are using can do real damage. Don’t trust the bleeders and such; they can fail off or come undone.
I hope you have the bleeding rods for discharging caps if there happens to be residual voltage. The worst thing you can do is to start being careless because something has worked the last hundred times.
Of course you know all this from doing vacuum work; but I felt obligated to emphasize it. I have gotten (and seen) very bad hits from apparently trivial oversights.
