20110253522 | METHOD AND SYSTEM FOR PURIFYING LIQUID USING WASTE HEAT - A method and system for purifying liquid using waste heat is provided. Initially, a liquid is mixed with an anti-sealant agent in a first filtering unit to form a liquid mixture. Thereafter, the liquid mixture is filtered in the first filtering unit to separate foreign objects from the liquid mixture. Subsequently, the liquid mixture is heated in a pipe arrangement connecting the first filtering unit and one or more second filtering units to generate steam. The steam obtained from the heated liquid mixture is then purified in the one or more second filtering units. Thereafter, the purified steam is condensed in the pipe arrangement to obtain the purified liquid. | 10-20-2011 |
20130068608 | HEAT EXCHANGER STEAM CONDENSER WATER DISTILLATION - 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. | 03-21-2013 |
20130112189 | SOLAR STEAM GENERATION - 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. | 05-09-2013 |
20130133323 | SOLAR STEAM GENERATOR - 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. | 05-30-2013 |

20110209475 | HIGH TEMPERATURE SOLAR THERMAL SYSTEMS AND METHODS - High-temperature solar thermal systems and methods are described. In one aspect, a system is described that includes a heat engine power conversion system, or a “heat engine,” with a fluid working medium. The heat engine includes a first input, a second input, and a heat exchanger. The first input receives heated high temperature tolerant particles, or “heated particles,” from a solar energy collection and distribution component that is coupled to the heat engine. The heat engine's second input receives the working fluid medium used to drive the power cycle in the heat engine. The heat exchanger transfers heat from the received heated particles to the working fluid medium, and thereby, energized the heat engine's power cycle. | 09-01-2011 |
20110214668 | GLASS SOLAR RECEIVER WITH BIFURCATED ANNULUS RESPONSIVE TO THERMAL DIMENSIONAL CHANGES - A solar power conversion receiver is described. In one aspect, the solar power conversion receiver includes a circular glass envelope and an absorber tube encapsulated within the circular glass envelope. An annulus, positioned between the circular glass envelope and the outer perimeter of the absorber tube, is bifurcated by first and second fins operatively coupled to the circular glass envelope and the absorber tube. These fins create first and second annulus compartments that are substantially sealed off, or independent, from one another. The first and second fins are ductile and responsive to expansion and contraction of components in the solar power conversion receiver due to temperature effects. In one aspect, gas in the lower annulus compartment stratifies with cooler gas interfacing with the encapsulating glass envelope, and hotter gas interfacing with the hotter absorber tube, resulting reduced natural convection heat loss as compared to conventional glass encapsulated receivers. | 09-08-2011 |
