If this holds up, I could open my own fuel station based on my coffee intake:

Researchers are reporting they have successfully made a high quality biodiesel from spent coffee grounds. They estimate that the coffee ground biodiesel industry could generate as much as $8,000,000 in profits annually using waste from US Starbucks stores alone.

Ok, maybe I don't drink that much coffee, but it's still pretty cool :)
