A team of researchers at Hewlett Packard Co.'s HP Labs claim that "hypothetical farm of 10,000 cows could power a 1 MW data center -- or on the order of 1,000 servers." The American Society of Mechanical Engineers conference held this week received a paper from the team mentioning that cow manure from dairy farms or any other digested farm waste could produce electricity. Though the scheme is still on paper, but the idea is already seen becoming a success in a number of farms. How it works is, organic matter uses the process of anaerobic digestion to produce a methane rich biogas. This power could help in operating data centers.
