High Value High Voltage

Hello everyone,

    I'm trying to do some DC coil stuff & was wondering if anyone
know some good ways to have HVDC caps of values about 1F. I'd like
to make each one about 10Kv Using poly sheets would make the cap
huge. I've seen some Maxwell k-film & other stuff like that in my
Surplus Sales catalog, but was unsure of it's exact ratings. If you
have any ideas or anything let me know.
