Description

Grow algae, clean wastewater, capture carbon dioxide to ultimately produce biofuel.

NASA has invented an innovative method to grow algae, clean waste water, capture carbon dioxide to ultimately produce biofuel. The invention consists of floating flexible plastic enclosures, and photobioreactors with semi permeable membranes. This new cultivation system is made of lightweight material and deployed offshore. This avoids problems of land costs and competition with other land uses. The surrounding waters provide infrastructure, cooling, and some mixing from wave action. Ideally, this cultivation system is filled with nutrient-rich domestic waste water and a source of CO2 to promote the growth of algae and to remediate pollution.
