Just about now Grabby is going to dump some math on your collective cornucopian heads. he will show you that there is not enough land or energy in biocrops to have any impact on our upcoming liquid-fuel problems.

Futhermore, the free stuff you biofdiesel dumpster-divers use is not really "free." You are diverting old cooking oil from a waste stream that supplies soap manufacturers. A waste stream that happens to be owned by some very tough people named 'Soprano.' Wait until they figure out who is cutting into their profits

I recall a Simpsons episode where Homer had this scheme to suck out waste grease into the back of his waggon car for resale. He ended up butting heads with the mob-- Doh!!

Hey pstar, do you think that maybe the mob will become the biggest providers of biofuels from waste grease? I wonder how much biodiesel you can get out of one of those "uncooperative people".

its like hydrogen, most the product is used up making itself
its a no winner
no brainer.

If hydrogen is produced by wind generators or solar electic panels (PVs) and is used to store this energy instead of in batteries, none of the product is used making itself. This is the best way to make/use hydrogen in my opinion, and would justify fuel cells.
