ABSTRACT:
A solar water still (10) includes an enclosure assembly (12) and an evaporation assembly (14) that float on a body of source water and that are readily collapsed and folded for storage or transport. The enclosure assembly includes a transparent conical dome (20) covering a collection reservoir (18) and an inner float ring (16). The evaporation assembly is placed in the center of the inner float ring. During operation, solar radiation induces water to evaporate from the evaporation assembly. The water vapor is then condensed and collected by the enclosure assembly.
