Best Inventions of 2009: Edible Race Car

TIME’s picks for the best new gadgets and breakthrough ideas of the year, we’ll feature some of the ones we find interesting.

If it’s impossible for a race car to be “good” for the environment, maybe it can at least be a little friendlier.

Meet the WorldFirst F3 project, a Formula 3 race car developed at England’s University of Warwick: it has carrot fibers in its steering wheel, potato starch in its side mirrors and cashew-nut shells in its brake pads. The whole thing runs on a biodiesel mix of chocolate and vegetable oil.

In a small effort to make the car even greener than it already is, the designers coated the radiator in a substance that converts ozone emissions into oxygen.
