Researchers from the University of Warwick have been demonstrating a 'green' racing car made from recycled materials and which runs on bio-diesel made from chocolate waste products. The Formula 3 car, named Worldf3rst, was built by scientists from the university's WMG spin-off (formerly Warwick Manufacturing Group). It's based on a car made by manufacturer Lola. To see Ben Wood from the University of Warwick explain how the car was put together, see our video below. You can also see Dr Guy Barker speaking about the university's 'bio-reactor' which converts waste products into usable ones.
