I actually a special on this technology on the History Channel's modern marvels. They pump the CO2 out of big producers of it (anyhting with combustion from facotires to power plants) into these huge fields of tubes of algae. The algae grow at phenomenal rates with all this CO2 being pumped into their little tubes and they harvest it. So basically they get their Carbon from CO2 via PHOTOSYNTHESIS.
