    Abstract: A light pipe for use in aqueous environments comprising an optical rod capable of total internal reflection, and disposed in the optical path of a light source such as a light emitting diode or other source. The optical rod has frosted and unfrosted portions, such that the light is propagated distally along the rod at the unfrosted portions, but a portion of the light is coupled out of the rod into the aqueous environment at each of the frosted portions. The relative sizes of the frosted portions are arranged so that substantially the same light power is coupled out of the rod at each frosted section, thus facilitating rapid and uniform growth of algae in the aqueous environment.

  • Patent number: 8790913
    Abstract: A pneumatic bioreactor includes a vessel containing a fluid to be mixed and at least one mixing device driven by gas pressure. A first embodiment includes a floating impeller that rises and falls in the fluid as gas bubbles carry it upward to the surface where the gas is then vented, permitting the impeller to sink in the fluid. The floating impeller may be tethered to a second impeller with a flexible member and pulley. The mixing speed is controlled with electromagnets in the vessel acting upon magnetic material in the impeller or its guides. In another embodiment, floating pistons mix the fluid, pushing it through a mixing plate with one or more apertures. In a third embodiment, the mixing device is a rotating drum with bubble-catching blades and rotating mixing plates with apertures. The top of the vessel for these mixers may include a closed top and sterile filters.

    Abstract: A simple alternative to separate filamentous bodies of Monostroma latissimum algae (large green algae) as seed stock. The filamentous bodies are easily separated and prepared for cultivation. At low luminosity (50 ?m mole s?1m?2), the filamentous bodies grow into the filamentous colony. If the filamentous colony is in turns irradiated at the luminosity greater than 100 ?m mole s?1m?2, it is turning into fronds. Thereby the filamentous bodies are evenly distributed into small segments so as to penetrate through the cotton rope for algal mass cultivation and further grow into fronds at high luminosity.

  • Publication number: 20140137941
    Abstract: Solar-redshift systems comprise an integral array of redshift modules, each having at least a focusing device, a target, and a quantum-dot vessel. The quantum-dot vessel contains quantum dots that emit light having an emission wavelength. The focusing device directs incident solar radiation through a focusing gap and toward the quantum-dot vessel, or into a slab waveguide and then toward the quantum-dot vessel, causing the quantum dots to emit redshifted light having the emission wavelength. The redshifted light is directed to the target, examples of which include a photovoltaic material or a living photosynthetic organism. The target has increased sensitivity or response to photons having the wavelength of the redshifted light. A trapping reflector component of the quantum-dot vessel prevents loss of redshifted light to the environment outside the solar-redshift system and allows undesirable infrared light to be removed from the system.

  • Patent number: 8722390
    Abstract: The object of the present invention is an atmospheric bioremediation system focused to reduce the Carbon Dioxide content in the Earth's atmosphere. The disclosed system includes an apparatus to distribute iron in low oxidation states such as zero or plus two trough out the photic region of high nutrients low clorophylls (HNLC) oceans over a period of time. This special apparatus is needed to provide a slow and continuous release of the iron to prevent premature precipitation. It has been shown that microalgae growth is usually initiated by the addition of iron and its sustained feed in water whose only limiting nutrient to prevent algal growth is iron itself. It has also been shown that southern oceans are a possible large batch area where iron is the limiting nutrient.

  • Patent number: 8510985
    Abstract: A cyclic system composed of several integrated cyclic processes and a method for production of cement and or quicklime, ammonia, desalinated water and an excess of algae cells. The system comprises of: at least cement/quicklime production plant, at least ammonia production plant, at least one water desalination unit, at least one photo bioreactor. The energy source of the system is sunlight energy. The CO2 produced by the system and other waste products are sequestrated and recycled for additional cycles of system operation. No CO2 is released to the atmosphere. The system produces a huge excess of algae cells that accumulates in arithmetic or geometrical progression. The excess of algae cells can fuel additional energy consuming plants attached to the system or can be used for other various purposes such as food and food additives.

  • Publication number: 20130180166
    Abstract: A method for enhancing gas-to-liquid transfer rate and algal growth using vertical membranes suspended over a pond, wherein the membranes are formed of fibers. An aqueous solution is applied to the top edges of the membranes through a series of headers. The membranes are exposed to a stream of gas containing soluble gas species as the aqueous solution migrates downwardly through the membranes by virtue of gravity-assisted capillary action. The aqueous solution collects the soluble gases from the gas stream, thus promoting the growth of photosynthetic organisms on the membranes and in the pond. The membranes facilitate a gradual introduction of the aqueous solution into the pond at a preferred rate of about 1.3 gallons per minute per linear foot of membrane for optimizing the transfer soluble species from gaseous phase to aqueous phase without rapidly acidifying the pond and harming the phototrophic organisms.

  • Patent number: 8479441
    Abstract: An apparatus for cultivation of phytoplankton and other autotrophic aquatic species in an aquatic medium in one embodiment comprises a plurality of liquid-impermeable transparent baffles, each forming an elongated trough-like enclosure, depending from a transparent top chamber, each baffle in communication with the top chamber, and two end walls for enclosing the top chamber and baffles. Introduction of water into the baffles sinks the apparatus in the liquid medium to the top of the baffles, leaving the top chamber above the surface of the medium. Light to which the top panel is exposed passes through the top chamber, the water in the baffles, and the baffles to encourage growth of selected microscopic organisms in the surrounding medium.
