San Francisco is on a roll. In April, the city banned plastic shopping bags, banned bottled water in some restaurants, and banned Styrofoam takeout containers. In another progressive step, plans are now under way to turn the copious amounts of waste vegetable oil produced by the city's 2600 restaurants into biodiesel. The goal: offsetting 20% of the diesel fuel used by city buses .

Had I not dropped for my Prius I would have loved to have geek'd out and built my own veggie oil car.
