Turning Crude Oil into Gasoline - DVD

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.

Sheriff Kilpatrick makes sure his town lives by the rule of the law. "We must not allow guns to do our thinking for us," he decrees. But even a man as determined as Kilpatrick has his limits. When marauding outlaws kill his wife and his son, he invokes a new rule: the rule of the gun. Richard Harris (A Man Called Horse, Unforgiven) portrays Kilpatrick, a deadly tracker seeking revenge. Kilpatrick is single-minded, unsparing, bullet-hard

Sand is great for a sandvox, but why would companies go through the trouble of mining tons of it out of the ground. Learn more about the geology of sand deposits, how frac-sand is mined and processed, how a sand mine company limits their environmental impact, and even how they are helping to preserve an endangered butterfly species. Going undercover as Inchkids on a mine tourInch our investigators reveal the technology and physics of a modern industrial sand mine. They focus on the science and practices that impact the environment while decoding the unique geology behind the secrets of what makes something as simple as sand so valuable. Find out how sand miners extract select zones of quality industrial sand without blasting ancient sandstone formations to smitherines.
