Publication number: 20230150838Abstract: A solar-powered distillation process converts saline water into potable water and useful solid residues. A solid material is heated by solar energy, and the solid material is brought into direct contact with saline water. Some of the water becomes steam and vapor, which can be condensed to produce potable water. The water-soluble salts within the saline water are precipitated separately, and collected for commercial use. Scale formed on the solid material can be removed, and the solid material reheated by solar energy, and the reheated solid material can again be used to heat incoming saline water in a continuous process.Type: ApplicationFiled: November 18, 2021Publication date: May 18, 2023Inventor: Pitaya Yangpichit

Patent number: 9903349Abstract: A solar chimney includes an elongated chamber having the general configuration of an hourglass. The chamber includes one or more heat exchangers for heating air in the chamber by solar energy. A turbine in the chamber is driven by updrafts of air created in the chamber, and the turbine drives an electric generator or other machine. An exhaust wind turbine assists in the production of such updrafts. A vertical axis wind turbine harnesses energy of wind in the environment of the chimney, and such energy is used to drive the exhaust wind turbine. Excess wind energy is stored for later use. A set of extendable and retractable vanes, mounted externally of the chimney, deflects wind, in the environment of the chimney, towards the vertical axis wind turbine.Type: GrantFiled: August 15, 2013Date of Patent: February 27, 2018Inventor: Pitaya Yangpichit

Patent number: 9617982Abstract: The solar chimney of the present invention comprises an elongated chamber having an inlet end and an outlet end, the chamber defining a path for fluid, such as air, from the inlet to the outlet. Air updrafts in the chamber drive an internal turbine which is connected to an electric generator, or to some other machine. The chamber has the general configuration of an hourglass; the diameter of the chamber becomes progressively smaller with distance from the inlet end, until the diameter reaches a minimum value, then becomes progressively larger, as one proceeds towards the outlet end. Disposed within the chamber are one or more heat exchangers for heating air in the chamber by solar and/or wind energy.Type: GrantFiled: April 5, 2012Date of Patent: April 11, 2017Inventor: Pitaya Yangpichit

Disposed within the chamber are one or more means for heating air in the chamber by solar and/or wind energy. In particular, there may be a solar collector inside the chamber which receives direct solar radiation from outside the chamber. The solar collector may also be configured to function as a heat exchanger.Type: ApplicationFiled: April 5, 2012Publication date: December 25, 2014Inventor: Pitaya Yangpichit

Patent number: 4981563Abstract: A membrane electrolysis cell, particularly suited for producing chlorine, caustic soda and hydrogen by the electrolysis of brine, has its cathode formed by a static bed of a packing material capable of withstanding the cathodic conditions confined between the membrane and a current distribution-baffle plate, parallel and spaced from the membrane. The current distribution plate defines a space within the cathodic compartment through which de-gassed catholyte downflows toward the bottom of the compartment for raising again through the interstices of the cathodic static bed. The internal recycling motion permits a rapid evacuation the gas evolved at the cathode from the interstices of the cathodic bed and prevents catholyte stagnation within the cathodic bed.Type: GrantFiled: January 17, 1990Date of Patent: January 1, 1991Assignee: Panclor (Thailand) Co., Ltd.Inventors: Placido M.
