Beware of the DriveWithWaterFuel ad on this site. It's got a couple of pop-ups that come on after you try to go back. I'd never buy from a company which pushes its crap with a tactic like that!
Hmm,
I don?t know which site you have clicked,
but this link:
http://www.overunity.com/hho.htm
is okay with no popups.
Has one of the best infos on HHO gas production on the net.

It was one of those ads in between comments on a post that touted "the three best hho systems". I'll check out your link in the am. Thanks.
