  • Patent number: 9453457
    Abstract: A portable on-demand hydrogen supplemental system is provided for producing hydrogen gas and injecting the hydrogen gas into the air intake of internal combustion engines. Hydrogen and oxygen is produced by an electrolyzer from nonelectrolyte water in a nonelectrolyte water tank. The hydrogen gas is passed through a hydrogen gas collector. Nonelectrolyte water mixed with the hydrogen gas in the hydrogen gas collector is passed back thru the tank for distribution and water preservation. The system can be powered by the vehicles alternator, a standalone battery, waste heat or solar energy. The system utilizes an onboard diagnostic (OBD) interface in communication with the vehicle's OBD terminal, to regulate power to the system so that hydrogen production for the engine only occurs when the engine is running. The hydrogen gas is produced it is immediately consumed by the engine. No hydrogen is stored on, in or around the vehicle.

    Abstract: Synergies in recovery of reverse osmosis (RO) membrane process reject waste and forward osmosis (FO) membrane process water extraction, using such osmotic process byproducts in applications for makeup to evaporative cooling towers, concurrent with use of specific corrosion and scale inhibition methods that permit tower water discharge reduction to approach zero blowdown. Such synergies are derived from methods for application of subsequent RO feed water and reject wastewater with pre-treatment steps, and FO process optimization steps to permit water quality and economic performance efficiencies when used as makeup to evaporative cooling systems.

  • Patent number: 9150429
    Abstract: The solar, water desalination system includes a desalination chamber where fine water droplets are injected upward by an air atomizer towards an air-cooled condenser. Hot saline water is ejected vertically upward to double the contact time between the droplets and the surrounding air. The air is preheated by solar energy in parallel with an auxiliary heater to prevent lowering of the droplet temperature. Pumped air functions as a condensation media and to pull the salt water into the atomizer. This arrangement improves the heat and mass transfer inside the desalination chamber.

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.

    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.

  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

  • Patent number: 8863517
    Abstract: Systems and methods for solar steam generation are described. The systems and methods include disposing a plug in a closed top outer shell of a solar steam generator, which may define a small annular space between the plug and an interior of a transparent housing disposed atop the outer shell. Raw water is transferred into the outer shell of the solar steam generator, up into the small annular space between the plug and the interior of the transparent housing. Concentrated solar energy is directed at the transparent housing to boil raw water in the small annular space. Stray concentrated solar energy may be focused at the transparent housing to aid in boiling raw water in the small annular space. Steam rising from the small annular space is directed through a cavity extending from a top of the plug, downward through a steam outlet pipe, out of the solar steam generator.

  • Publication number: 20140262737
    Abstract: An apparatus and method for desalination use kinetic energy in ocean waves as a power source. The apparatus comprises a wave tank and a condensation tank, the wave tank and condensation tank being connected by two pipes, each with a one-way valve, that produced a cycle of water saturated air from the wave tank to the condensation tank with a return of relatively desaturated air back to the wave tank following condensation of water. The wave tank captures the up and down motion of the waves and converts it to a pumping action. Air inside the wave tank is compressed when a wave comes in and has a negative pressure when the wave recedes. A saline water spray is introduced during wave troughs. Water evaporates into the negative pressure air hydrating the air. When the next wave comes in the water level rises inside the wave tank pressurizing the air.

  • Publication number: 20140262739
    Abstract: Embodiments relate to techniques for forming underground caverns, and also to desalinization processes that may be employed in conjunction therewith. Particular embodiments form a salt cavern by introducing heated water into a salt formation, followed by removal of the resulting brine to leave a salt cavern. The injected water is provided as a result of a desalinization process of the brine. Concentrated brine resulting from the desalinization process, is used to form a solar pond whose stored thermal energy provides the heat source for the injected water. The resulting underground cavern may be employed to house large volumes of materials such as pressurized natural gas, liquid hydrocarbons, or compressed gas for energy storage. Also disclosed is a particular desalinization process based upon a Regenerative Evaporative Distiller (RED) structure, which efficiently leverages low grade heat available from the solar pond by relying primarily upon a latent heat of evaporation and condensation.
