Water is essential to life. The origin and continuation of mankind is based on water. The supply of drinking water is an important problem for the developing countries. The increasing world population growth together with increasing industrial and agricultural activities all over the world contributes to the depletion and pollution of fresh water resources. The rapid increasing need for energy and environmental concerns has focused much attention on renewable energy resources. Among the non-conventional methods to desalinate brackish water or seawater, the cheapest method is solar distillation. The yield of the single basin solar still is very less and it increases considerably when the solar still was built with copper sheet. They greatly improve the rate of evaporation and the rate of condensation on the cooler surface. The efficiency is higher for solar still made up of copper sheet and it can be increased further by providing a heat absorbing materials inside the still. This cost-effective design is expected to provide the rural communities an efficient way to convert the brackish water in to potable water. The theoretical results agree well with the experimental ones.
