Chinese dairy harnesses cow-pat power

A gigantic Chinese dairy farm is now the world's largest methane farm, turning a massive source of greenhouse gas emissions into a lucrative renewable energy source. Huishan Dairy in northeast China has installed gas-powered generators that will capture methane from fermenting cow manure, reports Technology Review. Its system is 10 times the size of typical cow manure methane capture programs - fitting for an operation with a quarter of a million cows. The plant will process the waste from 60,000 of Huishan's 250,000 cows to produce 5.66 megawatts of power. This is enough electricity to meet the needs of 3,500 American-size households, Tech Review says - which means it will service many more Chinese ones, because they use less energy.
