In a unique effort to recycle wasted energy, 8 teams of British eco-enthusiasts participated in a car rally from London to Athens in vehicles fueled by waste vegetable oil.This 11-day, 2,500 mile (1 mile equals 1.609344km) feat was achieved with diesel converted from an estimated 350 litres of wasted cooking oils borrowed from eating joints, that otherwise head for landfills or the sea. "I think that this is the first long-distance car journey in Europe that has relied on restaurants and burger bars as an informal network of filling stations," said Andy Pag, who organized the rally. For the event, vehicles which ranged from a Renault to old taxis, were converted to run on vegetable oil. The 'unconverted' ones availed themselves of easy to use portable "fuel pod" processors, carried in transit vans, for converting the cooking fat into biodiesel. With such a novel use of otherwise wasted cooking fat, this rally highlighted the alternatives to fossil fuels as well as controversial biofuels like ethanol.
