No hard source voltage, just tranduced potentials. If you were to ground to earth really well or implement a germanium diode in place of the silicon diodes, you should be able to achieve the same effect irl. Only limit on your values would be the limit limit of your capabilities in coil making and technical analysis... Hehe
Flip the spdt sw. To start small current flow over a 400 MV potential. Use LC tank cells to boost output values. When able, install a transistor amplifier ckt and keep building your potentials to source to other components...
A little volts goes a long way...
