Teardown of a PC Power Supply

Had a pallet of military surplus capacitors, packaged as 3 big (soda can sized) caps on a blade frame and wrapped in conductive foil, plastic, then heavy paper. From the 70s and they were fine when i got them in 1997.

I wired up an unwisely huge bank out of them for some fun HV experiments. They were in a shed outside and could self charge to useful levels in the course of a windy day. Dont recall the actual numbers but it could vaporize dimes handily.

Reading that, I wonder how much solar power you'd need to charge them to that level? And if that could be applied to complement solar/wind power?

I tried some halfass "comb" antennas but wasn't seriously attempting to harvest static electricity to useful purpose. There's some "joule thief" circuits available cheap and easy now that make me wonder if its possible.
