Well, in Stans patent, which Donald placed here, today, he doesnt talk about the EEC.
Just simple using voltage pulses from 650V till 2000V on a 3 inch tubeset.
The idea of getting HV pulses across a tube in water can only be done if you use very very tiny small pulses. You must stop pulsing as soon as current starts running.
Amps follow volts in a conductor with a 90 degree delay.
So, just use a duty that is around 25%?
Well, if it was all that simple.
