Patent number: 10556810Abstract: A water sterilizer powered by solar energy is described. A first check valve allows an increment of untreated water to flow from a reservoir into a boiling chamber where it is heated to boiling, and thus sterilized, by focused solar energy. A second check valve with a higher cracking pressure than the first valve remains closed, holding the increment of untreated water in the boiling chamber until the pressure of steam forces the second valve open, thus evacuating the chamber of now-sterilized water. Once the chamber is evacuated, the second valve automatically closes, and the first valve automatically opens, allowing another incremental sterilizing cycle to begin.Type: GrantFiled: May 5, 2018Date of Patent: February 11, 2020Inventor: Blaine Clifford Readler

Patent number: 10550008Abstract: A low energy fluid purification system and method of implementation including some embodiments having a vacuum-rated first chamber placed in or near a body of water with higher temperature near the surface and lower temperatures at greater depths. The vacuum-rated first chamber holds a quantity of non-potable water and a low pressure area less than or equal to the water's vapor pressure. Vaporization occurs when the higher temperature surface water is brought into contact with the low pressure area. A tubular vapor transport passage allows the vaporized water to pass to a lower temperature and lower pressure condensation chamber. The lower temperature condensation chamber is cooled by lower temperature water from a selected depth below the surface. As the temperature of the vapor lowers, the vapor will condense. This condensation is collected as a quantity of potable water. Additional embodiments and methods are also provided.Type: GrantFiled: May 7, 2016Date of Patent: February 4, 2020Assignee: United States of American, as Represented by the Secretary of the NavyInventors: Craig A MacDougall, Dylan Switzer, Aaron Wiest
