NOVELTY - An energy recycling moving film solar still comprises double layered glass cover (4, 5).    USE - As energy recycling moving film solar still (claimed) for obtaining pure water from brackish water sources.    ADVANTAGE - The energy recycling moving film solar still improves efficiency of simple solar still for obtaining pure water from brackish water sources. The problem with commercial solar still is that their efficiency is low and is of order of only 25% to purify water. These commercial solar stills have single inclined glass plate which is placed on quadrilateral framework forming closed box. This glass plate acts as condensation surface for pure water. When box is exposed to sun, brackish water evaporates from base of box and condenses on relatively cooler bottom surface of glass plate. The problem with this practice is that glass cover allows heat of condensation to escape from solar still rendering it inefficient. The improved solar still overcomes this problem by using double layered hollow glass plate in favor of single layered glass cover. A thin film of water is present in this hollow space. This thin film of water absorbs heat of condensation and recycles it to solar still thus increasing its efficiency.    DETAILED DESCRIPTION - An energy recycling moving film solar still comprises double layered glass cover (4, 5). The two glass plates are hermetically sealed at edges by rubber gasket. The distance between upper and lower glass plates is 1-2.5 mm forming closed hollow space sealing. Holes are drilled on upper and lower glass plates for entry and exit of water respectively within hollow space of double layered glass plate. The glass cover is fastened to quadrilateral framework by metal clamps. The glass cover forms roof over quadrilateral framework making it closed box.
