Cow Manure Could Be Cheap Alternative to Gas
May 29, 2006 — The secret to cheaper gas could lie in cow dung.
The Vehicle Research Institute of Western Washington University in Bellingham, Wash., has been turning cow manure into fuel that can power a natural-gas car. Researchers are not shoveling manure straight into the gas tank but pumping the methane — a gas created by the manure — into the car.
They have some hard-working cows at a dairy farm in Lyndon, Wash., to thank for this experiment, which could mean cheaper car fuel for many people.
"We are talking about dairy cows," said Eric Leonhardt, an engineering technology professor and director of the Vehicle Research Institute. "So they are very well-trained. They go in one spot. They feed and do their business in one location. And then that material is pumped into a holding tank."
