Electric geobacter microbes
Scientists have engineered an amazing strain of microbe — a proteobacteria called a geobacter — that can generate electricity from oil-based pollutants and radioactive material. In other words, not only can the geobacter be used to clean up harmful pollutants, it can actually turn those pollutants into clean energy. Researchers are currently working to create geobacter-based fuel cells. Not bad for a microorganism.
