ABSTRACT:
A solar still assembly has a thermally-insulated pan which supports an open frame of elongated members. The pan has side walls which support the frame members, with one side wall being higher than the other side wall. One end of each frame member is attached to the top edge of the higher side wall while the additional support for each frame member is provided by the lower side wall. The frame members incline downwardly toward the lower side wall. There are several embodiments which teach alternative frame members for providing the additional support by the lower side wall as well as the manner in which a trough is formed from the frame members or is attached to the pan. In all embodiments, a thin-film, flexible, solar-energy transmissive sheet overlies the frame, permitting solar energy to enter the still and evaporate liquid in the pan. Condensate forms on the inner surface of the solar sheet and flows down the inclined surface into the trough.
