ABSTRACT:
An automated solar still is disclosed which incorporates a system of valves and other controls that halts production when the level of solar insolation is not adequate to support evaporation, admits water for treatment only when the still requires resupply, operates at nominal pressure by gravity flow and flushes out suspended and dissolved contaminants automatically. Production is halted under conditions of inadequate solar insulation by means of a temperature sensitive valve which is exposed to the received sunlight. In one embodiment, heating and evaporation occur directly in a central chamber. In another embodiment heating occurs in external panels and evaporation occurs from trays in an evaporation chamber. With changes in dimensions and proportions the system of controls may be used in solar stills for desalinating sewater.
