  • Patent number: 8877016
    Abstract: Systems and methods for solar steam generation are described. The systems and methods include moving at least one frame mounted optical focusing lens to track the sun in two axes and disposing a water boiler at a focus of each optical focusing lens. Raw water is pumped through an inlet at a bottom of each boiler and solar energy is concentrated, using each optical focusing lens, on each boiler, heating the raw water in each boiler and evaporating steam from the raw water. The steam exits each boiler, via a steam outlet pipe. Remaining salts and solids in each boiler are ground by rotation of salt grinding-cleaning gears. These ground salts and solids are drained and/or pumped out of each boiler from an exit in the bottom of each boiler.

  • 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.

  • Patent number: 8834683
    Abstract: Heat exchanger steam condenser water distillation is described. In one aspect, a water distillation condenser has a heated air conduit in air flow communication with a heat exchanger. A cold raw water compartment is disposed above the heated air conduit and at least a bottom surface of the cold raw water compartment disposed at an angle. A heated raw water channel is defined between the heated air conduit and the raw water compartment. A floor of the heated raw water channel is defined by a top of the heated air conduit. A distilled water trough is disposed below a lower extent of the cold raw water compartment.

  • Publication number: 20130001060
    Abstract: The invention provides an apparatus for frictionally heating one or more fluids to produce one or more distilled fluids and to separate impurities from the one or more fluids. The apparatus includes a housing for receiving the one or more fluids. The apparatus also includes one or more rotatable cylinders enclosed within the housing. The one or more rotatable cylinders include a plurality of friction elements. On rotating the one or more rotatable cylinders, the impurities are separated from the one or more fluids and the plurality of friction elements frictionally interact with the one or more fluids to generate vapors. Thereafter, the one or more impurities are collected in an impurity collector associated with the housing. The vapors generated due to the frictional interaction are received by one or more condensers which condense the vapors to produce one or more distilled fluids.
