There are already millions of diesel engines. All you need to do is adapt the new ones you manufacture to be able to plug in to the mains and idle when not in use, at compression ratios (including turbo) of about 20:1. I've posted this and other methane fantasies at http://docs.google.com/Doc?id=dfqvz524_22575bmd2
I'd be really grateful if people could either a) tell me how to improve the ideas b) shameless steal them and submit them, after removing my glaring mistakes By the way, I suggest that any 14yo german savants simply lie about their age, and get a forwarding address. With the aid of a stick-on moustache, they will almost certainly get away with it. A 2009/5/18 Alvia Gaskill <[email protected]> > > I posted below the details of the contest.
