  • Patent number: 10730762
    Abstract: A system for processing a fluid by generating water vapor through forced compression and rotation in a vessel includes capturing sea water for use in desalination processing in the vessel. Any fluid processed in the vessel, including sea water, can be used to create water vapor that rises to an elevation under its own power. After condensing the water vapor to liquid again, the condensed liquid falls upon a hydro-electric generator to generate electricity that is stored for later use. Brine output from the system can be recycled for re-processing through the system to increase water vapor yield. The wet brine output may also be dried to produce dried brine for subsequent processing of salt and other minerals.

  • Patent number: 10161114
    Abstract: This invention is designed to create potentially unlimited commercial fresh water at a significantly reduced cost in relation to existing fresh water creation systems such as sea water desalination. This invention pumps coastal atmospheric air through sealed pipes to ocean water depths (ideally) of approximately 100-305 meters, or (ideally) into the local ocean's thermocline layer. Fresh water condensation occurs inside the sealed air pipes as cold ocean water chills the outside of the pipes. Condensation fresh water flows via gravity to the low point in the sealed air pipes where a powered fresh water pump is located. This powered fresh water pump then pumps the accumulated condensation water to the ocean surface and then on to shore as usable fresh water. The pumped-in air, now dehumidified, is piped to the surface and returned to the atmosphere.

  • Patent number: 8961652
    Abstract: A method for removal and condensation of vapors from within an enclosed space (120) is disclosed. An enclosed space (120) containing material (110) is surrounded by an insulative permeable layer (130) having a lowering temperature gradient (230) between the inner surface (220) and the outer surfaces (240). The insulative layer (130) may also be covered by an impermeable layer (140). Heating the material (110) in the enclosed space (120) causes the formation of vapors at a positive pressure within the enclosed space (120). Vapors pass through the inner surface (220) of the insulative permeable layer (130) and contact the permeable materials and are condensed by the lowering temperature within the insulative layer (130). The condensate liquid passes downwardly through the insulative layer (130) for collection.

  • Patent number: 8951391
    Abstract: A solar distillation apparatus utilizing a substantially vertical reactor assembly is disclosed. The reactor includes a tubular outer shell, a base, a cap, and a central tension member. The annular space between the outer tube and the central tension member forms the reactor chamber. Seawater or other feed liquid enters the reactor chamber through the base plate. Reflected or direct solar energy heats the feed liquid, generating low pressure vapor. The vapor exits the reactor through the cap structure or the base. The concentrate left behind settles by gravity to the bottom region of the reactor's liquid column. Extension tubes on the feed openings allow feed liquid to enter the liquid column above the concentrate layer and avoid excessive mixing of the feed liquid and the concentrate. The concentrate exits the reactor through one or more openings in the base.

    Abstract: A solar water purifier is disclosed. The solar water purifier uses waste heat from a solar panel, or direct heat from the sun, to boil, evaporate, and condense water to create a stream of purified water. In one embodiment, a boiling tank is mounted under and in direct thermal contact with a solar panel to absorb waste heat. In another embodiment, a transparent wall of the boiling tank is directly exposed to solar energy. Unpurified water enters the boiling tank from an inlet tank. Once in the boiling tank, a stream of steam and water vapor leaves the tank and is allowed to condense within a condenser. The condenser is located within the inlet tank, such that the heat recovered during condensation is used to preheat the inlet water to the boiling tank.

  • Patent number: 8906203
    Abstract: A system enables the use of solar heat energy together with electromagnetic energy and optionally energy produced during fermentation of organic products to produce fresh water from salt water, wastewater and water vapor contained in the atmosphere. The resulting fresh water can optionally be rendered drinkable by adding mineral salts at the desired concentration. A method and reactors combine electromagnetic and solar heating steps and optionally heat exchanges with a hot gas originating from combustion, to evaporate droplets of a spray produced from salt water or wastewater. The vapor obtained is separated from the salt particles or agglomerated impurities during evaporation using a cyclone system. The vapor can then be transported over a large distance before being condensed by bearings, in order to separate the water from any additives or impurities that may be present. Additives can be used to lower the vapor pressure of the liquid water and to facilitate droplet fractionation.

  • Publication number: 20140346032
    Abstract: A desalination system in the form of a submerged gas evaporator that includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a fluid inlet that provides a fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. During operation, gas introduced through the tube mixes with the fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence, thereby promoting vigorous mixing and intimate contact between the gas and the fluid, which leads to a more efficient and complete evaporation. Additionally, vapor exiting the submerged gas evaporator is condensed in a condensing unit thus precipitating vapor into a liquid for removal.
