Not necessarily to hijack the thread, but cos I'm naturally tangential...although this isn't too far removed...ya all seen that welding machine that uses water and electrolytically catalyses it into gas, that burns up to 10k degrees, but has no flame, and turns right back into water? Well, the guy got the idea that he could use it in his car. Turns out he got like 20 or 30 miles to the cup or so. He's smart in that he's no Tucker, and is working with 'a car manufacturer'. But it makes you think, doesn't it?
