The technology looks to efficiently remove algae from water potentially permitting the economic use of algae based products to be used for sustainable fuel, food, feed, chemicals, plastics and many more products and materials. 
This novel algae harvesting system could dramatically reduce the energy cost necessary to harvest, dewater, and dry algae and potentially transform the economics of algae-based biofuel production by removing a major barrier to large-scale commercialization.
