ABSTRACT:
A solar still includes a relatively shallow chamber with a pyramid shaped transparent cover and a transparent base. The still also includes a pair of rollers and an endless heat absorbing belt rotatable about the rollers. The still is positioned to receive solar energy passing through the transparent cover and impinging on an upper surface of the heat absorbing belt in order to vaporize seawater within the chamber. The efficiency of the still is increased by one or more mirrors disposed below the still for reflecting sun light up through the transparent base to impinge on a lower outer surface of the belt to enhance the vaporization of the seawater. One or more fans are also provided for cooling the cover to enhance the condensation of water that will then run down the cover and into a pure water receptacle.
