Today, in the 32nd ScienceBeer, Farzin was our Science Brewer. Farzin is a Professor in Leibniz Institute and works on Institute for Integrative Nanosciences. Have you ever thought about human body as an eternal (of course not literally) source of electricity? Imagine that your gadgets can be all charged via the electricity produced by your body! Imagine that all implemented medical devices in patients body no longer would need battery replacement. These and many more futuristic ideas are not far from realization. Today Farzin explained how human body can be used as a big eternal fuel-cell. Thank you Farzin.
