  • Apparatus and method for producing and harvesting algae
    Patent number: 8689482
    Abstract: An apparatus and method are described for producing and harvesting algae. The orientation of the production substrates is critical for maximizing production as a function of water area utilized. By employing an array of algae production substrates in a vertical configuration relative to the water surface, the yield of algae production per area of open water is increased substantially relative to prior art algae production systems.
    Type: Grant
    Filed: February 6, 2012
    Date of Patent: April 8, 2014
    Assignee: College of William and Mary
