Bacteria belches to power batteries?

Meet Shewanella oneidensis at CNET, a metal munching bacteria that literally poops power. With more study, and perhaps a bit of tweaking, this micro organism could be put into fuel cells to increase their life. They could keep the liquid in the cells from becoming contaminated by excess waste and turn in into free electrons.
"Researchers at Rice University and the University of Southern California have embarked on a
project to harness the power of Shewanella oneidensis, a microorganism that essentially spits
lightning. Rather than consume oxygen to turn food into energy, Shewanella consumes metals.
The waste product of its metabolic process comes in the form of excess electrons stripped from
the metals but not recombined in subsequent chemical reactions. The bacteria lives in soil, water
and other environments and can extract its necessary nutrients from a variety of materials."
