Solar Stills: A Comparative Review of Sustainable Technology

Abstract

Technological innovations vive incessantly, to provide pragmatic and innovative solutions to
 routine problems. At times conventional methods with modern adaptations prove to be effective and efficient
 solutions in a realistic manner. In a low resource setting, simple low-energy technologies are likely to succeed.
 One such technology available for water purification is the solar still. Solar stills use sunlight, to kill or
 inactivate many, if not all, of the pathogens found in water. This paper attempts to consider the prominent
 variants of solar stills available and compare the operational and functional parameters. An attempt has been
 made to provide an integrated comparative assessment so as to identify the optimal performance indicators
 in deciding the technology adaptation.
