I'm wanting to build a dc power source of 1 million volts more would be nice but ill start with a million and work my way up from there. Any suggestions would be helpufull. Is it possible to build a 1 million volt capacitor or should i build a capacitor bank to smooth out the ac current after its rectified or do you have a better suggestion for me. I'm wanting to build a coil gun with 1 million volts and not have to wait for capacitors to charge all the time just want to have a high voltage supply and fire it whenever. Any help will be greatly appreciated.
