I was given a 42uF 12KV oil capacitor. Any suggestions for having some high tech fun with it?
It's rated for oscillatory currents, pretty old, but it is in good cond. electrically. I can easily and safely charge and discharge it. The thing is, it was free, and I suppose I couldn't turn it down. Now what? The highest voltage I would possibly need a filter cap for is 4500 for an amplifier, so that's out. The "oscillatory currents" rating makes me think it was for energy storage and high frequencies. It is likely from LANL surplus.
Can crusher? disc launcher? I'm mainly interested in suggestions for projects that will focus on a fast discharge and high peak power levels, and do not require a lot of additional items, but I am open to any decent ideas.
