A DETAILED TECHNICAL REVIEW ON SQUARE PYRAMID SOLAR STILL

Mechanical (Renewable Energy) Engineering

Availability of pure drinking water in sufficient quantity with permissible quality is a primary requirement of all human being as well as animals and also for agriculture and industrial uses. Solar desalination is non-conventional method of extracting salt and other impurities from saline water to get pure drinkable water which utilizes the freely available solar energy for this conversion. Solar still is device used to achieve this conversion. But the major limitation of solar still is its lower productivity and because of that continuous technical improvements and researches are carried out by various researchers. Pyramid solar still is one of these improvements for conventional old design of solar still to increase the productivity. This technical review gives the detailed ideas about different configurations and advancement in pyramid solar still. This paper also describes the various modification and fabrication strategies for pyramid solar still.
