The power of crap

ScienceBlog reports on  a new device that produces power while treating sewage

A new technology is being developed that can turn raw sewage into raw power. The device, called a microbial fuel cell, not only treats wastewater, but also provides a clean energy source with the potential for enormous financial savings, according to scientists at Pennsylvania State University.

David Bagley, a scientist at the University of Toronto, has calculated that the energy potential in wastewater is almost 10 times the cost to treat it. ''If we could achieve just one-twentieth of that power, we could break even,'' Logan says. ''We're confident we're going to be able to do more than that.''
