Story in Ananova today "Choc-powered trip to Timbuktu Two British adventurers drove to Timbuktu and back in a truck fuelled by chocolate. Andy Pag, 34, and John Grimshaw, 39, made the 2,600-mile trip in salvaged Ford Iveco Cargo lorry and Land Cruisers, using biodiesel made from waste chocolate. They set off from John?s home at Poole, Dorset, on November 26 and arrived in Mali, West Africa on Boxing Day, reports The Sun. They overcame sand storms and corrupt customs officials, and drove through a town where days later al-Qaeda terrorists shot dead a French family, to deliver a biodiesel processing unit and the vans to a charity. Andy said: "We wanted to do a trip that wouldn't have a detrimental effect on the environment." The pair, who reckon they saved 15 tonnes of carbon emissions, now plan to fly to China in a plane powered by rubbish." How have they saved 15 tonnes of C02 emissions? Surely the Carbon dioxide is emitted regardless of whether the diesel is chocolate based or normal oil based stuff. (also 15 tonnes?? not getting many miles per gallon then - typical C02 per gallon of diesel is 11.9Kg so 1260 gallons used in 2600 miles -2 cars = 4mpg )
Why didn't they put the vehicles on a ship to West Africa and driven from there. That would have reduced their carbon emissions even further. I think this carbon footprint business is getting out of hand.
