Must be a "Flux Capacitor" running on banana juice?? Developing voltage
from quasar sources.

Well i saw, some corcuit , called voltage doubler, with capacitor and diodes
in series, doubling voltages, the capacitance and diodes it will jack up
voltage....

Not from a battery, unless there are other circuit elements
besides capacitors and diodes in series. (BTW they aren't
in series in a voltage doubler, but we know what you mean)

Sure there is. You just need the electronic equivalent of a pump. One
way works something like an ignition coil does. You apply 12 volts
across an inductor till the current ramps up to some value, then turn
that currnet off, very quickly. The inductor produces a large voltage
in an attempt to keep the current going. You pass that pulse through a
high voltage rectifier and dump it into your capacitor.

The flyback transformer in any TV or monitor is such an inductive
component. Got any junk monitors sitting around?

Oh, yeah, right! Tell the guy to hook his 300V cap to a flyback!

NOT!!!

Ken, don't do that. Do a bunch of reading first, about ohm's law, and
voltage, and current, and stuff.
