conclusion the chokes plus the secondary form a pulse forming network system that charges thru and discharges all the energy on the water later, the diode is key to let the secondary become part of it also on the discharge time..
the charging will align the molecules and polarize them electronically, the discharging will induce the resonance in the molecule
the circuit is tuned to a certain water resonant frequency . the pulses are interrupted or gated when the system reach resonance of the molecule to allow the molecule to rearrange ..
when a gas go out with positive polarity and the cell remain negative it will become an electron source reversely it become a sync it can be whatever depending on how the system of discharge is designed...
