ABSTRACT:
A solar heating and evaporation plant is described which can be used to either produce distilled potable water from salty water or to heat water for industrial or domestic purposes. The plant includes a plurality of substantially equally spaced solar stills mounted on a black colored solid metallic heat conducting plate, each said solar still including: (a) a vertical, cylindrical container having a diameter of about 2 to 4 feet for holding a body of salty water in which the salty water has an exposed upper surface, said container having thin side walls with the inside and outside faces thereof being colored black; (b) a floating cover layer on said body of salty water including a black colored floating perforate plate or black colored floated particles; (c) an annular trough surrounding the top periphery of said cylindrical container, said trough for holding a transparent cover for the container and to collect condensed water; and (d) a transparent plastic cover including a lower vertical cylindrical portion which merges into a semi-spherical top portion, the transparent cover having a height greater than its diameter and for condensing water vapor and causing the condensed water to flow down the vertical cylindrical portion for collection in the annular trough.
