This is the beginning of an article from http://news.bbc.co.uk on Friday 23 November 2007, about a new, unusual bio-fue l from chocolate.. I think this is crazy, but wonderful: individuals have fantastic ideas on how to replace petrol. Why don't the big companies have some also? Here in France, when you don't live in big towns, you can't do anything without a car, there is no local public transport. I would like to make a gesture for the planet, but it's just impossible.. I admire these two men who are going to show everybody that we don't need petrol for transport energy and that other things are possible.

Two British adventurers are setting off on a journey across Europe to west Africa in a lorry powered by chocolate.

Andy Pag, of London, and his co-driver John Grimshaw, of Poole in Dorset, were leaving Mr Grimshaw's home town on a cross channel ferry on Friday. They are travelling in a Ford Iveco Cargo lorry powered by fuel that began life as chocolate, in a bid to raise awareness of green fuels.

The 4,500 mile (7250km) trip across the Sahara should take about three weeks. The pair will take a small processing unit with them to convert waste oil products into fuel, which they will then donate to an African charity, along with the lorry.

If we can make it to Timbuktu with bio-fuel there's no reason why motorists can't use it on the school run or on their commute to work

They are taking 2,000 litres (454 gallons) of bio-diesel made from 4,000kg (8,818lb) of chocolate misshapes, the equivalent of 80,000 chocolate bars, to fuel their adventure. But they will not be able to dip into their tank if they feel peckish as the bio-diesel does not look or smell like chocolate. The fuel is made from cocoa butter, which has been extracted from the waste chocolate.
