Coffee Replacing Gasoline?

There's a neat little article up stating that coffee grounds could be processed into biodiesel. This invention could help reduce our dependence on fossil fuels, one cup at a time:

That's the idea behind a new study that turned used coffee grounds into biodiesel fuel. Coffee will probably never replace petroleum, but discarded cappuccino scraps might someday help reduce our impact on the environment, say the study's authors. They imagine a day when the byproducts of your latte end up in the gas tank of your car -- with hardly any waste left behind.

"It's a very simple two-step process," said Susanta Mohapatra, a chemical engineer at the University of Nevada, Reno. "We can definitely make a big impact on our environment with fuel made out of nature."

Cool.
