In a breakthrough that could change life in dry regions, Omar Yaghi, a chemist at University of California, Berkeley and a 2025 Nobel Prize winner, has developed a machine that can produce up to 1,000 litres of clean drinking water every day from air. Created by his technology company Atoco, the system works even where humidity is below 20%, offering new hope to places facing severe water shortages. Who is Omar Yaghi and what did he invent? Omar Yaghi is famous for developing metal-organic frameworks (MOFs), advanced materials that can trap gases and liquids very efficiently. Using this same science, he designed a machine that captures moisture from the air and turns it into drinkable water. The system is portable, runs off-grid, and is about the size of a shipping container, making it useful in remote regions with little infrastructure. How does the device work? The machine uses special materials that absorb moisture from the atmosphere. It then releases this moisture as clean water using low-grade heat sources like solar energy. Because it does not need electricity grids or pipelines, it can work in deserts and isolated communities where traditional water systems are difficult to build. Where was it developed and tested? The technology was designed at the University of California, Berkeley and is now being commercialised by Atoco. It has already been tested in extremely dry locations, including Death Valley, proving that it can function even in harsh desert conditions. Why scientists are excited about it Experts say producing 1,000 litres of water daily from air at just 20% humidity is something never achieved before. The device combines smart chemistry, energy efficiency, and real-world usability making it both scientifically impressive and practical for communities in need. Why this breakthrough matters Millions of people live in areas where wells, pipelines, or transported water are expensive or unreliable. This machine offers a cleaner and more sustainable option by creating drinking water directly from air using solar heat. It could reduce dependence on heavy infrastructure and imported water supplies. New future for desert communities Unlike many experimental technologies, this system is ready to scale. As climate change increases drought worldwide, devices like this could turn dry air into a dependable source of water bringing relief to regions that have struggled for decades.
