That staple of British haute cuisine - "fish & chips" - produces a lot of waste used vegetable oil across the nation. Now, a group known as the Low Impact Living Initiative (LILI) is organizing courses to teach drivers, car-fleet owners, and others how to convert this waste product into biodiesel. With vehicle fuel prices continually on the rise and heavy taxation, a gallon of diesel fuel costs well above the equivalent of $10 in the UK. Brits could see huge fuel cost savings by switching to biodiesel and there is no tax to pay on biodiesel production up to about 660 gallons per person. The only downsides are that the exhaust fumes may take on a fishy aroma and all those extra deep-fried fish & chips the Brits will have to eat could bulk up the obesity epidemic.
