Thanks John,

I'm now finalizing the PCB to drive this cell. ;)

sweet :)

does your circuit have a PLL in it to track the resonance?

No, unfortunately I have not found any signs of resonance.

The circuit is going to be my Stable Gated PWM.

Right now I'm testing the durability of using copper, so far so good, I drove this cell hard using up to 20 AMPS, and there is no signs of copper degradation, even at 20 AMPS, TAP water with KOH remains Chrystal Clear.

Thats a great new discovery , copper is very cheap compared to ss .

stephen meyer explains that the stainlees plays a key role in production because of its semiconducting properties. im gonna make a thread with all his radio blogs..

Well I`ll be doing with s/s , I dont believe copepr will do good with high voltage . And I believe Claudio will see some negative effects due to copper sometime in the future .

When you are using chemicals/electrolyte to do electrolysis, you have a chemical reaction going on inside the cell. If you listen to the electrolysis crowd on youtube they say 316 ss is better than 304 because it has more of something fancy and less of something else. but this is for exposure to a chemical reaction

When you use high voltage, it is a physical process of opposite electrical attraction, so the only "exposure" going on is simply the contact of the water/hydrogen/oxygen against the ss, so there is no chemical reaction to be contained.

316 ss is not needed for high voltage, simply because there is no chemical reaction, it is a physical process, and the 304 ss is cheaper (law of economics) and is still inert to the process.

As for copper. in a high voltage situation exposed to water, hydrogen, and oxygen, i don't personally know of any effects/reactions they will have with the copper, but i would guess it would be minimal.

As for copper. In a electrolytic environment, you are exposing the copper to a chemical reaction with potassium/sodium as well as water, hydrogen, oxygen, and i am not sure what the reaction with potassium/sodium is with copper, it my be perfectly inert to the process. I will ask some chemistry friends about it and see what they think. Stan says that even some types of platinum will erode in this process too, so that lends to the idea something vicious is going on in a electrolysis cell.

As long as you are having good (or bad! since we learn from those too) results then keep it up :) I just wanted to outline the differences between some common thoughts about materials as i have come to learn.

Ok, Today I went to do a test using the copper cell, just to find out that all the solder points got loose, every single wire that was soldered to the copper tubes got loose.


The copper itself looks ok, so looks like the KOH disolved the solder.
