Solar-powered desalination system requires no extra batteries
MIT engineers have built a solar-powered desalination system that removes salt from water at a pace that closely follows changes in solar energy. It automatically adjusts to any sudden variation in sunlight, maximizing the utility of solar energy. The system can produce large quantities of clean water regardless of sunlight variation throughout the day without any batteries or supplemental power supply. It is geared towards desalinating brackish groundwater, a huge untapped source of potential drinking water.
