Engineers at UCLA have genetically modified a bacteria to consume CO2 and produce isobutanol as a waste product. Isobutanol has shown some promise as a gasoline alternative.
This new method has two advantages for the long-term, global-scale goal of achieving a cleaner and greener energy economy, the researchers say. First, it recycles carbon dioxide, reducing greenhouse gas emissions resulting from the burning of fossil fuels. Second, it uses solar energy to convert the carbon dioxide into a liquid fuel that can be used in the existing energy infrastructure, including in most automobiles.
Sounds like a win-win.
