From garbage to gas

Dr. Stephen Paul, from Princeton University's Plasma Physics Laboratory, has found a way of turning garbage into 90 octane fuel, which he can sell for US$1.80/gallon. Petrol is currently selling at round $2/gallon in the US. If it stays at that price, Paul might be able to convince automobile manufacturers to produce cars that run on 90 octane fuel, and enough people to convert their cars.
