A formula 3 race car that researchers from the University of Warwick in Britain have retrofitted is seen at the MIT Energy Conference 2010 in Boston, Massachusetts March 5, 2010. Fueled by leftover chocolate and with components made from carrots, potato starch and flax, the world's first sustainable Formula 3 racing car has a top speed of 135 miles per hour and can go from zero to 60 in 2.5 seconds.
