Patent ID: 7857945

Claim:
A solar still comprising: a chamber having a transparent base and a side wall surrounding said base for confining a mass of water at a pre-selected level in said chamber and means for adding and removing water from said chamber; an inclined transparent cover comprising a glass plate, a distilled water receptacle and a base of said cover, said inclined cover receiving solar energy impinging thereon and passing there through and extending outwardly beyond said chamber so that distillate flows down said cover and falls outside of said chamber and into said receptacle; a pair of rollers and an endless heat absorbing belt having an upper and lower outer surfaces passing around said rollers in said chamber below the level of water and means including a solar powered motor for rotating said heat absorbing belt so that solar energy passes through said inclined transparent cover impinging on said upper outer surface of said heat absorbing endless belt to thereby heat said belt; cooling means including a solar powered fan for cooling the surface of said cover; and reflecting means for reflecting solar energy disposed below said chamber for reflecting solar energy up through said transparent base and onto said lower outer surface of said belt to thereby add heat to said belt whereby water is vaporized by said belt and condenses on said inclined cover and flows down into said receptacle.
