An apparatus for the desalination or purification of water comprises a non-solid vessel (3) having a bottom defining an opening, the vessel (3) capable of being partially submerged below the surface of a body of water, a pan (5) located within the vessel (3), the pan (5) being flexibly connected to the inner wall of the vessel (3) and being located beneath the surface of the water (13), a lens fixably connected to the top of the vessel (3), wherein the lens is focused beneath the surface of the water (13) and above the surface of the pan (5) means for varying the orientation of the vessel (3) in accordance with the location of the sun, and means for condensing steam generated in the non-solid vessel (3), whereby steam generated in the non-solid vessel (3) is condensed outside of the non-solid vessel (3). A method for the desalination or purification of water comprises the steps of containing a body of water within a vessel 3, the vessel 3 having a lens fixably attached at the top and bottom defining an opening, located a pan 5 just below the surface of the water 13, focusing the lens just beneath the surface of the water 13 and just above he bottom surface of the pan 5, condensing water vapor, re-filling the vessel 3 with water as the water is converted to steam, and periodically re-orienting the vessel in a manner that tracks movement of the sun.
