WorldChanging: Turning Emissions Into Fuel With Algae:

Isaac Berzin has developed a method of capturing CO2 from smokestack emissions using algae, and turning the result into biofuels including biodiesel, ethanol, and even a bio-coal substitute. His process, based on technology he developed for NASA in the late 1990s, captures more than 40% of emitted CO2 (on sunny days, up to 80%) along with over 80% of NOx emissions; in turn, it produces biodiesel at rates-per-acre that could make a full conversion to biofuel for transportation readily achievable. Berzin’s company, Greenfuel, has multiple test installations underway, and expects to have a full-scale plant up and running by 2008 or 2009.

A great article on a very promising technology – with due coverage of potential downsides.
