We've all heard about cars powered by wacky biofuels, including switchgrass and leftover French fry oil. Now, two British men who love the environment are trekking from Britain to Timbuktu in a truck whose fuel comes from cocoa butter extracted from waste chocolate (as in, like, misshapen Easter bunnies).
The vehicle is a Ford Iveco cargo truck, and as it travels 4,500 miles to Timbuktu, it will burn 2,000 liters of biodiesel originating from 4,000 kg (8,800 lbs.) of misshapen chocolate. That's enough of the sweet stuff to make 80,000 chocolate bars.
On Friday, the chocomobile crossed the English Channel by ferry, and after a sweet ride through France and Spain, it will hop onto another ferry to Morocco. Once it vrooms through Mauritania, it will plow through Mali's deserts until it arrives at Timbuktu, the city once regarded in the West as being at the ends of the Earth and which today is in a region that is being buried under sand.
The two Brits behind this stunt are, of course, trying to bring attention to biodiesel, a renewable resource that generates lower carbon emissions than fossil fuels. It seems unlikely that fueling vehicles with cocoa butter could be achieved at a large scale—that would require a tremendous amount of chocolate or, perhaps, tanning oil—but if the men's journey makes more people aware of the benefits of biofuels in general, that would be a sweet success.
