Neat how-to and video from Troy…“This is my hydrogen generator that I built Using stainless steel switch plate covers. You may be asking, Why switch plate covers? Well in the area I live in I was having trouble finding Someone to sell me a sheet of stainless steel and cut it for me. So I was in the Home Depot (a local hardware store) And I ran across switch plate covers made of stainless steel. All cut to size and all uniform. Well this made it too easy for me so I bought them About 36 @ $1.24 ea. I thought it was kind of expensive but what the heck. I was not getting the generator built waiting for a deal to drop in my lap. So on to the building of the h2 generator.” Thanks Jason! Link.
