During my 1st tests, there wasn't that much HHO, but the fact that there was only 0.6 volts across the cell using tap water, I find it very important.
I also used today's Melted Snow and it also works, the voltage across the cell using melted snow was about 9 volts.
now I started using 2 diodes, one resistor, and the WFC just like in Stan's VIC, and it also works, but the bridge works better.
now I need to achive higher resonance volatge maybe in the 50KV or even more. the higher the voltage, more electrons will have to flow thru water.
If any of you have a nice Tesla coil, that would be great for this. I would say put the bridge rectifier between the secondary and the top air capacitor.
Note:
The bridge I used was just 4 1000 volt ultra fast diodes. they worked just fine since the volatge across them will be way below 1000 volts even if resonance is at over 3KV.
