Algae Cleans Emissions Then Becomes Biofuel

The Israeli company Seambiotic has found a way to produce biofuel by channeling smokestack carbon dioxide emissions through pools of algae that clean it. The growing algae thrives on the added nutrients, and become a useful biofuels.


What the Lotus Taught the Engineers
