Agree with you Steve,
I'm thinking that this is the real stuff
Is exactly what Stanley Meyer wrote and talked about.
You charge the coils thru the capacitance and leakage and than it discharge a pulse of same polarity again in the water it doesn't matter what frequency.. but at resonance there will be the best condition since it behaves like a resistor... to gain voltage the discharge or collapse reversal must be fast enough to make it like an open circuit, so the electrical voltage zones are formed... The path must be of high resistance as stated by meyer or this must be take in account.
All this is because the leaking proprieties of water. at resonance it is a dead short... To get higher voltage just increase coils number... Its the only capacitor that gets charged and keeps conducting, interrupting this current is what should be needed.
I believe the vic design is this the secondary reverses the voltage when the pulse switchs off and this reverse bias the diode shutting it off to collapse the field of the all transformer. I think toroidal air core is the best option...
I think is all about sizing up...
air core, should be the best...
I think that a sensor should be added to detect when current stop to change to gate it there...
