Patented butanol farm turns algae into fuel

United States Patent 7,855,061 issued to Adrian Vance of Lakeport, California teaches a method of producing butanol with algae. As described in the only claim of the patent, the steps of the process include: collecting algae from the air, collecting bacteria from the soil, pressurizing tanks with CO2, placing the tanks in sunlight, agitating the tanks, harvesting algae off the top three inches, fermenting the skimmed algae with Clostridium bacteria, chilling for separation, and decanting the butanol that was formed.  Viewing the invention broadly, it is taking CO2 out of the air.  Even though the fuel would likely ultimately be burnt, releasing CO2 back into the air, the “carbon footprint” would be much less than equivalent processes that do not consume CO2.
