MIT scientists build PV-driven desalination system that reacts to changes in sunlight

The proposed brackish water desalination system uses photovoltaic electrodialysis to enable direct-drive desalination at high production rates. It already operated for 6?months on real brackish groundwater and was reportedly able to use 94% of the extracted PV energy. Researchers at the Massachusetts Institute of Technology (MIT) have built a brackish groundwater desalination system that is powered exclusively by PV power and is purportedly able to promptly react to small changes in solar radiation to maximize solar energy generation. "The solar-powered system removes salt from water at a pace ...
