Sewage to help Microsoft serve up web pages

Microbes feasting on raw sewage at a wastewater treatment plant will soon help power the cloud, thanks to a Microsoft project that will use biogas generated by the little bugs to run a data center.

Data centers are typically massive banks of servers that keep the Internet humming along nicely. They handle the flow of digital information when you order a song on iTunes, check your Facebook, send an instant message, or post on Twitter, for example.
