Yet there is also great excitement about an emerging application that could have some potential for green energy production - the use of biofilms to power microbial fuel cells whose fuel could be wastewater, as outlined at the ESF workshop by Cristian Picioreanu, Delft University of Technology. This exploits the ability of bacteria to transfer electrons to metals, which can be the cathode of a fuel cell, via the minute tentacles called phili extending from their surface.
