New $500 Billion USD Saudi City Will Deploy "Solar Dome" For Desal


Saudi Arabia, the world's largest oil exporter, plans to use solar energy to desalinate water in the planned $500 billion (Dh1.8 trillion) sustainable city of Neom. The "solar dome", which consists of an array of mirrors, will focus solar radiation on its glass and steel structure to heat seawater. Once it evaporates and precipitates as freshwater, it will then be discharged through outlets to reservoirs and irrigation channels, Neom said on Wednesday. The plant will not produce carbon emissions and create less brine than facilities using conventional reverse osmosis technology.
