Luckliy, or unluckily, I am meeting with a guy tomorow who has started an sintalling these commercially here in canada…he said he does not use any electrolyte, just uses tap water. He has units ready to show me on cars…but hes still behind the learning curve as he is creating HHO and using an efie, not just hydrogen. But nonetheless, if it is true and he doesnt use electrolyte but still uses stainless, would he still be leaking chromium into the water…? Either way I 'm making a cell that produces just hydrogen now, and trying to track down nickel plated copper, or stainless, or something…lol….I will touch base here when I know how this guys cell works without vinegar and produces 4.5 ltr.min…mindboggling….ive been thinking about it all damn day….
