Jitterati saves the world

Scientists have found a cheap way of making biodiesel from used coffee grounds:

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.
