An engineering team from MIT has designed a solar-powered groundwater desalination device capable of supplying over 1,000 gallons of clean water per day without requiring battery storage. The system adjusts its desalination activity in real-time based on solar power availability, making it ideal for remote communities with brackish groundwater.
The device uses electrodialysis, a method that removes salt from water using electricity. Unlike traditional systems, it dynamically responds to sunlight fluctuations, eliminating the need for costly batteries. A six-month field trial in New Mexico demonstrated its ability to produce 5,000 liters of water daily under variable weather conditions.
