<i>Shewanella oneidensis</i> Bacteria (IMAGE) University of East Anglia Caption University of East Anglia researchers are a step closer to enhancing the generation of clean energy from bacteria. Research shows how electrons hop across otherwise electrically insulating areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of electrically conductive 'stepping stones.' This natural process could be used to improve 'bio batteries' for portable technology such as mobile phones and laptops powered by human or animal waste.
