Zusammenfassung:	A method and apparatus are developed for separating the seawater into the caustic soda and fresh water by using green energy. The apparatus includes a water reservoir, a watercourse connected to one side of the water reservoir to flow the seawater through, positive and negative electrodes provided at the opposite sides of water reservoir and watercourse to electrolyze. At one side of the watercourse, the power is supplied to the electrodes, a solar light and a running water power generation are arranged for generating and supplying the electric power to the power supply. An evaporation tower evaporates the soda-containing water to separate caustic soda and fresh water from the water by electricity of vapor turbine generator. Thus, the present apparatus is capable to reduce the product cost of the fresh water and caustic soda, while it is preventing emission of the carbon dioxide from burning the fossil fuels without supplying the external power.
