has anyone come across this website?
It looks like he replicated what Stan done successfully. I think he first started with Dave Lawtons circuit, then he made some changes and simplified it.
Anyway, I have pulled many experiments, my initial experiment was with using aluminum plates. I found that two aluminum plates, both the size of stainless steel switch plates, draws very little current (.250 - .180 amps), and produces a considerable amount of hydrogen (15vdc). The problem with aluminum is the oxidation, the oxidation doesn't seem to hinder the hydrogen production, but it fills up the water with oxidation flakes and 'foam'.
So I decided to use stainless steel instead, in this case switch plates from Lowe's, although it does draw more current but doesn't have a oxidation problem. If you first start using the stainless steel plates you'll notice a "brown scum" on top of the water, and the plates start to corrode a little (with no electrolyte). So I found this forum some months ago, and I remember Ravi talking about the need to condition the stainless steel plates (or tubes). He said to condition it could take a few months. But recently I tried to condition the stainless steel using acid, or PCB board etching solution. You have to make sure you wash the plates thoroughly with water afterwards. It works very well, it only takes like 2 minutes! I pulled another experiment with the newly conditioned plates, and there was no brown scum or corrosion and it seemed the hydrogen production increased!
My next project though is building the pulse generator and voltage intensifier circuit. thanks....
