Omar Yaghi develops solar-powered device to harvest 1,000 liters of water from air daily

Professor Omar Yaghi, a chemist at the University of California, Berkeley and 2025 Nobel Prize winner, has developed an innovative device capable of producing up to 1,000 liters of clean water daily from air with less than 20% humidity. The technology, created by Yaghi’s company Atoco, relies on Metal-Organic Frameworks (MOFs), highly porous synthetic materials engineered at the molecular level to trap water molecules. The MOFs act like a ‘super-sponge,’ capturing moisture as air passes through the device. When heated using sunlight or low-grade thermal energy, the captured water is released and condensed into liquid form. Unlike conventional atmospheric water generators, Yaghi’s system is off-grid and energy-efficient. The machine, roughly the size of a 20-foot shipping container, can be deployed in disaster-stricken regions or arid areas, providing immediate access to safe drinking water. Growing up in a refugee community in Jordan without running water inspired Yaghi’s commitment to accessible hydration solutions. His long-term vision includes personalized water units for individual homes, akin to solar panels, potentially reducing dependence on centralized water systems. This invention arrives amid global concerns over water scarcity, offering an environmentally friendly alternative to energy-intensive desalination and promising to aid regions facing severe shortages.
