Gallery: Researchers Harness Bacteria to Make Clean ‘Bio-Batteries’


When you think of bacteria, the last word that might come to mind is “clean.” However, researchers at the University of East Anglia have made a breakthrough in battery technology that will allow microbes to generate clean electricity. Their work was published this week in the journal Proceedings of the National Academy of Sciences (PNAS), and it shows that the surface of the organisms can produce an electric current when touching a mineral surface. When lying directly on a mineral or metal surface, the bacteria can be “tethered” to electrodes, bringing the scientists one step closer to developing a battery powered by living creatures.

    It\\\’s very recent thinking of clean electricity, renewable energy and protect the planet. How long this preocupations will lead us?
    According to this post, we have reached the molecular and microscopic level. A clen energy like the microbial fuel cells can reduce the batteries that we use and, consequently, the heavy and toxical elements. These elements are very harmful to environment.
