+1 homework...
Man, the HHO subject sure stirs things up. While I don't buy the story that cars can run on this, or even that they run partially on it, I don't see any reason why it can't promote a more complete burn. I am as skeptical as everyone else, but instead of berating others, I built one for my truck and will report whether it works or doesn't work.....if it doesn't work, I'm out 50 bucks. There are folks out there that don't wait for others to tell them how to think.......I support them. History shows that the dreamers are the ones who make the difference.
Please excuse the rant
