This invention has a series of multiple parallel plates that form desalination chambers between them that have seawater or other saline water flowing down the inside of one plate of each chamber. Steam which is generated by solar heat or other heat source condenses on the outside of first chamber of the series on the plate, which has seawater running down it. This releases heat that evaporates the seawater. The vapor flows to the other wall (plate) of the desalination chamber and condenses, and this releases heat that flows through the plate to the next stage of parallel plates and evaporates seawater flowing down the other side of the plate. Each succeeding stage operates at a lower temperature than the previous stage. The final stage is cooled by the evaporation of seawater into the air. One embodiment of the invention has the parallel plates sloped at an angle to the horizontal so that the seawater flows down on the lower plate and evaporates with heat supplied from below. The vapor condenses on the ceiling of the chamber. Since each succeeding stage upward is at a lower temperature, the vapor pressure will be lower in succeeding stages. This pressure differential can be used to pump the seawater from one stage to the next higher stage.
