A pair of 2,000-gallon water tanks standing 15 feet tall occupy a cordoned-off portion of a parking lot down the street from Georgia Tech University's Carbon Neutral Energy Solutions Laboratory. They're being used to grow algae, but in an extreme and novel way. Researchers at Georgia Tech are seeing if it's possible to take existing carbon dioxide in the air, capture it and feed it to the algae. Once the algae is refined, it can be used in things from food to fuel.
