Solar-Powered Desalination System Revolutionizes Clean Water Access
Researchers from Kings College in London, MIT, and the Hemholt Institute for Renewable Energy Systems have developed a solar-powered desalination system that efficiently transforms saltwater into fresh drinking water. Unlike traditional energy-intensive methods, this system uses specialized membranes to separate salt ions from the water, adjusting both voltage and flow rate flexibly for consistent operation even in cloudy conditions. By significantly reducing the reliance on conventional energy sources and battery storage, this system offers a cost-effective and sustainable solution, especially beneficial for rural and developing areas facing water scarcity.
