Raw Sewage to Raw Power

Technology News has a report this afternoon on research into a new fuel cell technology that can turn sewage into power:
A new device called a microbial fuel cell not only treats wastewater but also provides a clean energy source, said researchers at Pennsylvania State University. . . . Similar in design to a hydrogen fuel cell, the microbial fuel cell captures electrons naturally released by bacteria as they digest organic matter and then converts the electrons into electrical current.
This exciting break through has obvious applications in wastewater treatment plants, particularly in developing countries. According to researchers, remote treatment facilities could one day power themselves as they treat water.
