Abstract : This invention relates to a solar still into which cold seawater is fed by means of a pipe perforated along its horizontal length. The seawater then flows down an inclined plane through a black wick material placed on top of a double or parallel plate base which serves as a heat exchanger that transfers heat from a working fluid to the seawater. The seawater in turn evaporates while flowing down the wick and the vapor condenses as pure water on the upper inner surface of the still transferring heat back to the working fluid which is being circulated through the upper cover of the still. The vapor condensate is collected as it flows down the inclined upper inner surface and in turn is drawn off; the working fluid is recirculated to continuously heat and then cool the distillate.
