As our readers know, the biofuels field of investigation is huge and there are quite a number of upcoming technologies that can make the renewable fuel without competing with feedstocks. The most notable of these technologies use waste streams and often also require less water to make biofuel. Popular Mechanics lists seven of these new biofuel technologies and provides some numbers about how and when they will be available: cellulosic ethanol (both biological and gasified), algal biodiesel, "gre
13 minutes into his Ted Talk (see video below), Dr. Craig Venter says fourth generation fuels, that is, biofuels made by bacteria from C02, are just 18 months away. The systems might work with sequestered CO2 and possibly even solar energy. What are the "modest goals" of this project?
