University Studies Way Of Fueling Cars With Cattle Waste
BELLINGHAM, Wash. (AP)–As gas prices continue to rise, more attention is being paid to alternative energy projects, like one at Western Washington University that would power cars with natural gas harvested from cow manure.
Students at the state university’s Vehicle Research Institute have developed a scrubber that removes the corrosive chemicals from the gases released by manure so it can power a natural gas car, The Bellingham Herald reported.
Eric Leonhardt, director of the institute, said the fuel that he calls “biomethane” is less flammable than gasoline and produces fewer greenhouse gases than manure left to decompose naturally in fields, according to the newspaper.
He estimates the natural gas would cost about half the current price of gasoline to produce, but emphasizes that is not the real benefit of cow power.
