The present invention relates to a method and apparatus of producing water from a saline solution ie desalination of salt water to produce pure water. The method comprises the steps of: 1) rotating the saline solution 210 in order to create a surface on the saline solution due to centrifugal forces acting on the saline solution; 2) slidingly engaging a frictional element, such as a jet of air, with the surface 322 in order to generate heat within the surface due to the friction between the frictional element and the surface, to cause water to vapourise from the surface of the saline solution; 3) moving the vapourised water away from the surface; and 4) condensing the vapourised water into a liquid. The frictional forces are claimed to be generated by either air or a skid biased into engagement with the surface of the water. The evaporator further comprises a nozzle arranged to propel air at the surface of the liquid and a gas outlet arranged to remove the air with the entrained vapour. The nozzle pipe and the outlet pipe are arranged opposite one another. The air may additionally carry plastic granules which are entrained in the gas in order to increase the claimed frictional effects. Centrifugal forces acting upon the saline solution provides a surface which is sufficiently stable to enable the frictional element to rub up against and frictionally work upon the surface to generate the heat required without the surface disintegrating. |
