Delicious, rich in antioxidants, and downright inspiring, coffee may fuel more than your neurons. From Treehugger, the mighty coffee bean makes good biodiesel.
Researchers Mano Misra, Susanta Mohapatra and Narasimharao Kondamundi figured that since coffee grounds contain about as much oil by weight, 11-20%, as more traditional biodiesel feedstocks such as rapeseed, soybeans, or palm oil.

That’s the equivalent of roughly 8 million barrels of oil, for those rushing to their calculators.
Unlike dedicated biodiesel crops, this would employ the waste product, giving the spent beans a second life. Genius. And most important:
