One Moos and One Hums, but They Could Help Power Google

A study by Hewlett-Packard shows how waste from cows on a dairy farm and heat from a data center nearby could be used profitably to produce electricity to run the data center.

“The average cow makes enough waste per day to power a 100-watt light bulb,” said Michael Kanellos, editor in chief at Greentech Media, a research and publishing firm.

According to H.P.’s calculations, 10,000 cows could fuel a one-megawatt data center, which would be the equivalent of a small computing center used by a bank. Mr. Kanellos has tracked both the data center and green technology industries and agreed that there was some convenient overlap. Computing equipment produces a lot of heat as a waste product, and the systems needed to create biogas require heat. So, there is a virtuous cycle of sorts possible.

Just a feel good article. More green paint.
