I believe in the theory, but I just don't see how a DIYer could do this SAFELY. What pressure's are exerted burning hydrogen vs gasoline? Is a typical combustion engine up to the task? I don't know
Secondly, I can't go buy the "Hydrogen 1000" to put on DirtySCREW. Someone somewhere would invest and mass produce these babies and become a multi billionare. And I think that there are smart enough people out there that want to help the good ol' USA that would turn down millions trying to be bought out because they know they would make BILLIONS.
Gtown--what are YOUR thoughts?
