Microbial fuel cell
Advanced biotechnology and genetic engineering offers one of the paths to making biofuels. At the ARPA-E Summit there were a number of university research efforts around "electrofuels," or fuels made directly from micro-organisms that consume carbon dioxide and energy to create a fuel. The idea is that these electrofuels can work more efficiently than the photosythetic route of growing plants and then extracting fuel from the biomass.
This display was from the University of Massachusetts which is working with microorganisms that feed on electricity and carbon dioxide to make organic compounds. Those compounds could then be converted into liquid fuels or other products.
