ONR’s microbial fuel cell generates electricity from mud

It is estimated there are approximately five nonillion (that’s 5x10 to the power of 30) bacteria on Earth, and although they generally get a bad rap, there are actually many beneficial bacteria that are vital to life on our planet. As we’ve seen previously, scientists are now looking to harness bacteria to produce electricity through microbial fuel cells. These microbial fuel cells (MFCs) convert chemical energy to electrical energy to offer a clean, efficient and reliable alternative to batteries and other environmentally harmful fuels. Recognizing their potential the Office of Naval Research (ONR) has developed an MFC that could revolutionize naval energy use by converting decomposed marine organisms into electricity.
