Patent number: 8465628Abstract: A solar energy conversion and distillation apparatus floats on a body of saltwater and includes a matrix of buoyant distillation modules that produce and collect distilled water for on-shore usage. The distillation modules and other buoyant structures are mutually joined within a peripheral seawall to form an atmospheric barrier, and each distillation module includes a submerged energy absorber layer to form an energy conversion chamber that confines a shallow volume of solar-heated seawater. Water vapor in the air above the confined water condenses on chilled heat exchanger conduits, and the energy absorber layer is water permeable so that confined water lost to evaporation and condensation is replenished with water from a thermal reservoir underlying the energy conversion chamber. Buoyant mistifier units in each distillation module enhance the evaporative surface area of the water vapor subject to condensation.Type: GrantFiled: May 3, 2010Date of Patent: June 18, 2013Inventor: Richard L. Henderson

Patent number: 7357849Abstract: A method and system for treating feedwater includes evaporating a portion of the feedwater in a first evaporation chamber so as to separate water vapor from the remaining feedwater. Droplets of the remaining feedwater are dispersed into a stream of hot air produced in a second evaporation chamber. The droplets evaporate and solids in the feedwater precipitate. The precipitated solids are collected in the lower section of the second evaporation chamber. Water vapor discharged from both evaporation chambers can be treated in a cyclone separator to remove residual solids therefrom. The cleansed water vapor output from the cyclone separator can be condensed to recover clean water. Dry solids can be discharged from the second evaporation chamber and the cyclone separator for recovery.Type: GrantFiled: March 9, 2006Date of Patent: April 15, 2008Assignee: Watervap, LLCInventor: Robert R.

Patent number: 7160469Abstract: Many areas in the world already suffer shortages of water, and others will suffer from it in the coming years. Therefore more efficient water sweetening is essential for our survival on this planet. The most commonly used water sweetening methods are: Reversed osmosis, distillation, electrodyalisis, and partial freezing. However, these methods suffer from low efficiency and high energy consumption, thus making them significantly more expensive than naturally obtained water. The present invention describes a system & method for efficient and low energy sweetening of water, based on borderline fast fluctuation between liquid to gaseous state and back, by using centrifugal forces to make water droplets fly at a high speed, so that they evaporate for a split second, the salt is separated, and they condense again. The present invention tries to make the process energy-efficient by enabling the use of lower speeds and smaller droplet sizes and solving various problems involved with that.Type: GrantFiled: December 26, 2002Date of Patent: January 9, 2007Inventors: Yaron Mayer, Boris Dechovich, Haim Gadassi
