IntroductionGreater growth of population and industries results in shortage of fresh water. Earth is almost covered with a larger water source and smaller land mass. People used to drink large amount of water for their thirsty need. Water available in the form of rivers, lakes cannot be consumed directly without pre-processing, as these need some purification process in order to remove bacteria and undissolved salts. In early days the possible method of getting pure water is heating the brackish water and condensing them back to get fresh water by burning fossil fuels. Due to the exhaustion of coal, crude oil and increases in global warming, the evolution of using renewable energy for getting fresh water evolved during the late 20th century. One of the best energy source applied is solar energy. Source of energy from sun is mostly environmental friendly and non polluting clean energy source. Basin type still is the most aged process of producing fresh water [1][2][3][4][5][6][7][8][9][10]. The fresh water conversion rate from the solar still system is predominantly depends on the solar intensity. The basin water temperature increases continuously due to heat energy emitted from the sun in the form of solar intensity. After reaching the boiling point of water, the water evaporates and it condenses on the solar still condenser cover. The various techniques employed in solar still, to raise the temperature of water and hence increases the productivity was studied from the detailed literatures reviews of Ravishankar et al. [11], Kabeel et al. [12] and Manokar et al. [13][14][15]. From the detailed literature studies it is clear that water temperature can be improved by either feeding waste warm water or pre heat the water by incorporating the different solar collectors or concentrators. Gupta et al. [16] theoretically analyzed the intermittent flow of waste warm water to the double basin solar still similarly same analyses was done by Yadav et al. in single basin solar still [17]. Sodha et al. [18] and Tiwari et al. [19] experimentally investigated the performance of solar still utilizing the warm water from the industry. Tiwari et al. [20] keep up a higher temperature difference between the water and collector cover by increasing the water temperature by flowing waste hot water in the basin and decrease the collector cover temperature by flowing the cold water above the surface of collector cover. This would results in increase in both evaporation and condensation

“…Investigations showed that the water height is inversely proportional to the productivity of the still (Eltawil and Zhao 2009;Kalidasa and Srithar 2011). The present study concerns with the effect of saline water height above the sand beds level (H ws ) on the daily productivity (24 h), as shown in Figure 6.…”

The amount of distillate water from a solar still depends on different parameters. The heat storage bed and water depth are the most effective parameters. In this work, different sand beds solar stills have been studied experimentally. The influences of sandy bed height (0.01, 0.02, 0.03, and 0.05 m), type of sand (black and yellow), and the water height above the sandy bed level (0.0, 0.01, 0.02, and 0.03 m) on the solar still performance have been investigated. The performance of developed sand beds stills was compared with the conventional solar still. Results showed that the heat storage bed (sandy layer) enhances the solar still productivity. The maximum increase in daily productivity of sandy solar still was achieved at sand beds height of 0.01 m and zero height of saline water above the sand beds level as compared with conventional still.A theoretical analysis has also been carried out, in which the results coincided with experimental results.

Figures 3,4, and 5 show the basic construction of an off-shore wind-power-distillation plant [9]. The wind turbine support column is immerged in the sea with its lower part and moored while at sea level, a floating closed shallow pond -the solar collector -is connected to it.…”

This paper reports and elaborates on the idea of a solar distiller and an offshore wind power plant operating together. The subject under discussion is a single-stage solar distillation plant with vaporization, using adiabatic expansion in the gravitational field inside a wind power plant supporting column. This scheme divides investment costs for electric power and distillate production. In the region of the Adriatic Sea, all electric power produced could be “converted” to hydrogen using less than 10% of the distillate produced
