For years engineers and scientists have tried to solve the massive problem of removing salt from sea-water to meet the growing demand for fresh water. Several land-based stills have been built in arid regions such as Kuwait, where local oil deposits supply the fuel, but production costs are high.
Scientists have been able to desalinate sea-water by using nuclear power. Basically what happens is that the water is heated until it evaporates. The vapour is the condensed through cooling and distilled to produce fresh water. The only problem is to have a source of considerable heat which is cheap to use. Such heat could come from nuclear reactors.
