Microbe Powered Power Source
A group of researchers at Rice University and the University of Southern California are working on creating a power source that is run off of bacteria that spits out electrons. The Shewanella oneidensis microorganism consumes metal and produces a waste product of electrons.In a fuel cell, the idea is that colonies of Shewanella will attach themselves to the anode, a component inside fuel cells and batteries that gathers electrons, and produce electrons.
"You can feed them pretty much what is available," said Andreas Luttge, an associate professor of earth sciences and chemistry at Rice. "The goal would be to feed them waste water and produce energy."

The research is funded by non other than the Department of Defense. Small robots powered by waste water or excess metal are an attractive offering to them.
