A water purification system comprises an inner tube 4 that receives water from a tank 1 and an outer tube 2 that receives water vapour produced by evaporation of the water in the inner tube using solar heat energy, wherein said water vapour is then condensed and passes through holes (9, figure 3). The condensed water passes through a one-way valve 5 into a tube 6 for direct use in an agricultural drip irrigation system or for collection for other uses. The water contained in the tank may be sea water. |
