Many extensive studies have been carried out to the problem of enhancing productivity, effectiveness and efficiency of single-basin solar stills. Solar still with sponge cubes in basin is studied by Bassam & Hamzeh. Hiroshi Tanaka constructed a basin type solar still with internal and external reflectors. Tiwari et al. used a multi wick solar still with electrical blower. Jim et al. used a multiple tray tilted still. John Ward designed a solar water purifier. Tiris et al. conducted experiments on two flat plate solar collectors integrated with a basin type solar still. Performance study on solar still with enhanced condensation was studied by Kumar & Kasturibai. Hussaini & Smith studied the effect of applying vacuum inside the solar still. Gnanadason et al. use suspensions containing nanometer-sized particles in vacuum solar water still (nanofluids).
