This is rather crackers but shows the bizarre lengths some are going to...
The story and picture below were stolen from the marvellous ecogeek website (click here for ecogeek).
"On May 5th, scientists at the University of Warwick in England unveiled a race car that runs on chocolate, or at least the waste from a chocolate factory. The car, built to Formula 3 specifications, is even more distinct because it's also built using biodegradable materials.
The steering wheel, seat and car body are all made from plant fibres from carrots, flax, soybean and various root vegetables. The engine runs on a mixture of vegetable oil and chocolate waste. The makers claim that it's the fastest biofuel car to also be made out of sustainable materials and I'm claiming that it will be the first car whose description makes people hungry. It's built to reach a top speed of 145 mph and drivers will take it out for a full-speed test run in a few weeks to verify its performance.
The makers are calling it the "WorldFirst Formula 3 Race Car" and are taking it on a tour of several races where it will be on display, including the European Grand Prix and Britain's Goodwood Festival of Speed".
Mark Forskitt made me LOL. He says (in the comments below):
"It is a comment on the food vs fuel dilemma we face as a post oil society, isn't it? It deserves a place in the Tate gallery, perhaps"
