A review of different solar still for augmenting fresh water yield

Due to the greater growth of population and industrial developments especially from the early 20th century, people living in remote villages suffer with shortage of drinking water. People living in urban and rural areas depend on surface and ground water sources, where these sources are majorly polluted by industrial waste. The use of reverse osmosis technique and other conventional technique appears to be a costlier method and requires a very large land mass. An economical method of converting the saline water to portable water is by using solar energy. Solar still desalination is one method of converting saline water into potable water by evaporation and condensation. Many researchers carried out extensive studies on the solar still desalination technique and this paper communicates a detailed review about the existing desalination technique by solar energy.
