Chocolate Powered Race Car

I just read an article on FoxNews.com about a race car that was built from parts derived from vegetables and runs on a fuel derived from chocolate. The car is 95% biodegradable and conforms to most of the International Formula 3 rules. I find it very interesting that a race car could be partly built from and powered from food. Automotive technology has been advancing very fast lately, but I have never heard of a car running on chocolate. Although this car cost over $200,000 to build, I hope that this technology is expanded because we really need cars that will run on renewable engergy.
