Microbes Produce Power As They Clean Nuclear Waste 90
An anonymous reader writes "Researchers at Michigan State University (MSU) have isolated and explained the phenomenon that causes microbes to generate electricity while cleaning up nuclear waste. The team is hoping to use their findings to create a microbial fuel cell that is capable of generating renewable energy while it cleans up environments exposed to nuclear waste. The bacteria the team studied is a kind of geobacter that is covered in a coat of tiny, natural nanowires that protect the bacteria from the toxic materials. While completing the complex task of stabilizing radioactive spills, the bacteria simultaneously creates energy that can be harnessed and used as a zero-emissions power supply."

You're forgetting about Hanlon's Razor.
The larger concern I have here -- a position taken that anyone in disagreement must be duplicitous, without even allowing an opposing argument to be first presented, is no way to have a serious discussion.
This is, indeed, great research. Why muddy the waters with a bunch of flamebaiting?

What this does is turning radioactive waste into living radioactive waste...
It's better than that. While the value of the bacteria generating energy seems utterly irrelevant, the bacteria do provide opportunities to concentrate the nuclear material , in other words, to remove it from the environment, and that's valuable. And maybe there is some minor value in the energy part, it could be a measure of activity.

The bacteria take uranium out of solution and turn it into nanowires outside their outer membrane. They have tested it outside in a uranium mine tailings pile. The goal is to build a bacterial water treatment cell that produces electricity while it filters out dissolved uranium.
This is not for generating power, the energy produced is a by-product. I doubt that the resultant energy would pay for it's own production. However, the electricity could be used to help pump water through the system, which is a neat trick and will help to reduce cleanup costs.
