Cows show potential to be the new power plants

A new study suggests that some of the microorganisms found in cow waste may provide a reliable source of electricity.
Results showed that the microbes in about a half a liter of rumen fluid – fermented, liquefied feed extracted from the rumen, the largest chamber of a cow's stomach – produced about 600 millivolts of electricity. That's about half the voltage needed to run one rechargeable AA-sized battery, said Ann Christy, a study co-author and an associate professor of food, agricultural and biological engineering at Ohio State University.
