Experimental investigation on the performance enhancement of single basin double slope solar still using kanchey marbles as sensible heat storage materials

Abstract The problem of water scarcity is increasing day by day due to various causes such as polluting the environment, urbanization, climate change due to the heavy usage of fossil fuels, less awareness in storing the water when it is available, etc. However, in seashore areas, the availability of fresh drinking water is very low. This demand motivated to suggest a low cost and renewable energy based desalination system to convert the brackish water into potable water. Solar still is a simple device which can convert the available waste or brackish water into fresh potable drinking water utilizing solar energy. The designed solar still was fabricated and tested under the normal atmospheric condition. Present work is to investigate the effect of kanchey marbles as energy storage material in the overall efficiency of solar stills. The performance of the solar still with kanchey marbles was 16.32% higher than the conventional still.
