A Smart Algae Harvester
To be a viable source for fuel, algae must be dried completely, but the most common way of doing so—spinning it in a centrifuge—is costly, inefficient, and often damages the plant particles. Algaeventure Systems has developed a more efficient drying system based on osmosis and other natural processes. After algal solution is placed on the AVS Harvester, a moving screen pulls the plant particles in one direction as a conveyor belt pulls the water in the other. The resulting thin algal deposit dries, creating flakes that can be processed to create fuel and food. Read more.
