Greaseball Challenge
Web edition: April 11, 2007
And they're off! The participants in this charity biofuel car rally are on their way from the U.S. East Coast to San Jose, Costa Rica. Powered by biodiesel, vegetable oil, waste grease, and other alternative fuels, the vehicles will all be donated to local communities at the end of the rally, which runs until April 27. Along the way, they're stopping to refuel at fast-food diners, farms, factories, and other unlikely pit stops.
