Maybe start with the series string lying on the ground and use a pully and some plastic rope to lift the stack up in the air as each one is charged, literally "erecting" a Marx generator. 30 would get you to about half a million volts. Without switches or spark gaps, discharge impedance would be low. Use two ropes, at the HV and and midpoint. After it's assembled, hold up the midpoint and let the hot end droop down towards ground in an inverted "V" shape. Or do it horizontally, with the caps in an almost-closed ring, on PVC pipe supports or hanging on plastic ropes from some trees or something. Now just walk around the circle and charge one cap at a time. Carefully. Or stack the caps and have each one have its own battery-powered flyback charger. Great fun on the 4th of July. John

Think nuclear battery, or lightning. It's an exercise in finding utility, then. How about exciting the plate of a vacuum tube? Then, you can feed a 'suitable' frequency into the grid and get whopping AC power output from a transformer on the cathode circuit.

A reverse Van Der Graph Generator ? A constantly rotating Variable Capacitor with comutator contacts to apply the high voltage at Min Cap and then bleed off the converted charge at Max capacitance? Q=CV Perhaps a cascade of them in series? ................ Zim |
