You are talking about a Joe Cell, made by a bloke in Australia called Joe in or around Coffs Harbour NSW.
Apparently its a hydrolisis cell which goes past he stage 1 of just making Hydrogen and starts making Orgone (at stage 3) which is at this stage a mystery energy and the cell self propagates as well.
Alot of hippies are into this orgone too and its some sub atomic particle like a gamma particle which an internal combustion engine can run on.
Trouble is theres alot of inconsistancies and I dont think anyone has conclusive proof that it actually works. Sure I looked into it too, and even made my own cell, but it just made hydrogen which is simply too dangerous as a fuel.
Apparently you have to think positively to make orgone and people who havent made it work havent had the "vibe" to do so. After that I started to turn off the idea. I dont need vibe to make my race car go faster, just something that works.
Anyway this group of Joe Cellers is around hiding under the cover of darkness cause they all reckon Asio and the CIA and fuel companies are out to get them for taking away the worlds economy.
I think if you want really cheap alternate fuel that really works, go to your local fish and chips shop and grab a few gallons of their used oil, filter it to ten microns and run it in your diesel car. Id rather burn the stuff than see it go into landfill. Both Mythbusters and Top Gear have both proved it works and if I had a diesel Id give it a go too.
Hey look dont get me wrong, if you legitamately get a Joe Cell to work I will be the first one to buy one off you, but I wont hold my breath.
