Don't know how I ran into them but they are on Ebay. Just type in hydrogen generator, and you will find them. Sounds like it might work, but I am leary of it. What do you think? The system generates hydrogen to be mixed in with your regular gas, supposedly boosting your mileage.
I just looked at it, and he doesn't know why it would help, and I'm not sure if it is a scam or not. The process he is after makes more oxygen available, and that would be the results he would get, not the hydrogen. I know a guy from near my hometown that bulit something similar that did as this guy claims, but his casing was plastic, not stainless.It took him years to get it figured out too, so I really can't comment on this particular setup.
