Weird Bio-diesel source

Like the plot of a strange green Sci-Fi movie there is a story in Forbes about a doctor that made bio-diesel from human fat. We know many Americans have a weight problem, and that can effect fuel consumption.
But while this disturrbing concept is poetic in some respects, the idea of fueling your vehicle's with human fat may bring a disorder to eating and weight control that would make gorging and purging look almost reasonable.

Java Diesel

New research shows that waste coffee grounds can be used to make bio-diesel. The press release from the American Chemical Society states that spent coffee grounds have about as much oil as traditional virgin bio-diesel feed stocks.

The resulting coffee-based fuel — which actually smells like java — had a major advantage in being more stable than traditional biodiesel due to coffee's high antioxidant content, the researchers say. Solids left over from the conversion can be converted to ethanol or used as compost, the report notes.
