Dave Knott (2917251) writes "Argentine scientists have found a way to transform the gas created by the bovine digestive system into fuel, an innovation that could curb greenhouse gases that cause global warming. Using a system of valves and pumps, the experimental technique developed by Argentina's National Institute of Agricultural Technology (INTA) channels the digestive gases from bovine stomach cavities through a tube and into a tank. The gases — which otherwise are commonly known as burps, or "eruptos" in Spanish — are then processed to separate methane from other gases such as carbon dioxide. Each head of cattle emits between 250 and 300 liters of pure methane a day, enough energy to keep a refrigerator running for 24 hours."
