Solar-Powered Desalinator by MIT Turns Seawater Into Drinking Water With Zero Electricity MIT engineers have created a breakthrough solar-powered desalinator that can turn seawater into clean drinking water without using any external electricity. This compact, low-cost device is designed to operate anywhere sunlight is available — making it a powerful solution for coastal villages, disaster zones, and remote areas facing water scarcity. • The system uses sunlight to heat and evaporate seawater,
