Did you ever consider the fact that the fuel in your car's gas tank is mostly ancient sequestered carbon about 400 million years old? But part of that mixture is also modern recycled carbon made from today's renewable fuels like ethanol and biodiesel. In this program you'll discover how science and technology can convert corn, corn oil, beef fat and even used French-fry grease into modern biofuels. Learn how engineers convert the stored energy in a kernel of corn into high-octane fuel that makes your engine run smoother while reducing the percentage of greenhouse gas from your exhaust.
