Not long ago, a group of 13 students from Middlebury College in Vermont purchased an old school bus and the equipment to convert it to use biofuel - to run the engine on some alternative to gasoline. In this case, they built it to run off of old cooking grease. That's right, used vegetable oil. The theory being that because most restaurant owners pay to have their used grease hauled away, they would happily allow a group of students such as this the chance to pump all they need. What do you know - the bus made the trip of 4500 miles from Vermont to Washington, powered mostly by used vegetable oil and the kindness of strangers' kitchens.
