  • Patent number: 8434626
    Abstract: A system and related method for concentrating biological culture and circulating biological culture and process fluid is provided. The system includes a continuous flow separator that removes excess fluid from the culture medium, resulting in a “concentrated medium” of fluid. The concentrated medium is then passed along for further processing to capture the biomass. The overflow, i.e., the extracted fluid, from the continuous flow separator is reintroduced into the container in a manner to circulate the culture medium. Thus, energy from the concentration step is utilized to circulate the culture medium, alleviating the need for significant additional structure for circulating the culture medium. In this manner, the system grows and captures biological material in an energy and capital efficient manner.

  • Patent number: 8307820
    Abstract: A solar reflector assembly is provided for generating energy from solar radiation. The solar reflector assembly is configured to be deployed on a supporting body of liquid and to reflect solar radiation to a solar collector. A solar reflector assembly comprises an inflatable elongated tube having an upper portion formed at least partially of flexible material and a lower ballast portion formed at least partially of flexible material. A reflective sheet is coupled to a wall of the tube to reflect solar radiation. The elongated tube has an axis of rotation oriented generally parallel to a surface of a supporting body of liquid.
