Car Exhaust now good

See all those millions of tonnes of car fumes that are made every day had to have some practical use every now and then. Now some guys in Adelaide are proposing using the cars exhaust to run some kind of air conditioning. I mean thats a pretty sweet deal and all, the car runs on less fuel, you get mighty cold and pass out from the carbon monoxide and crash into a tanker filled with fuel. Now thats a pretty good deal all round really.
