ABSTRACT:
A low-pressure desalinization in a water chamber having an open end submerged in a water supply such as an ocean. An air exhaust pump draws air out of the water chamber to lower the surface tension of an upper stratum of water, which is thereby converted to vapor and subsequently condensed to nonsalinated water and collected in a U-shaped trap with a pair of sealing, closable valves. Moreover, a velocity enhancing parabolic channel is included for efficiently utilizing the potential energy of the fresh water. The fresh water is conveyed from its height at the top of the water chamber to a turbine via a velocity enhancement parabolic channel which enhances the velocity of the water for the turbine. The desalinator also includes a plurality of strips of sheeting partially immersed in the water being desalinated and drawing water therefrom via capillary action to increase the surface area of the water being subjected to the vacuum.
