ppm stands for part per million and is considered as 1mg per litre of water

rain water here have around 4 ppm so it may be in the micro molar range

i would like to point one thing... the cell concentrate some of the ions of all the water in between the plates altering the ppm between the plates and of the rest of the bath

How do I get 3,000C  well that is a plasma project. 
Creating high voltage spike with little or no current that can be done.
The ion exchange or the ion path I believe is one of the ways to get some good HHO if that’s what you want.
Just add a bit of KOH powder, like many are doing, lowering the resistivity of the water and then you could use the voltage spike, high voltage but not kv’s, or then go to parallel system and use the high circulating currents.

i guess this is the way indeed.. I'm in a loop thinking of how the resonance is going to help us...

i was thinking about using  high value resistor in series with the water to get only few milliamps to try monitor the voltage as function of frequency...

as for adding a high value resistor the water as in distilled is already too high.
so if you are going to use a small amount of KOH powder too bring this down, and you want to use resonance then you can do it some different ways to control the current.
You can start with a voltage control then change to current control.
Or you can go another way, if the frequency is high, and the voltage is high, it does not have to be in the kv’s range.  With the copper coil and the rise time T being short then the current as it is lagging the voltage any way will not have time to get very high, low current or next to nothing.

a nice doc.
But alu electrodes with koh?
Without any type of powersupply they must have seen hydrogen gas...

hahaha thats true =)

 hi if they used alum with KOH the will not last long but lots of gas if it is set right  that is why the use SS with KOH
