Researchers at MIT have developed a solar-powered device that extracts water from air, even in the world’s driest places. This groundbreaking invention is about the size of a window and operates without electricity, making it highly sustainable and efficient.
The device uses a special hydrogel material enhanced with hygroscopic salts, which attract water vapor from the air. When the sun heats the device, the water vapor turns into condensation and is collected as clean, drinkable water. No extra filtration is needed, as the process ensures the water is already purified and safe for drinking.
This technology was recently tested in Death Valley, California, one of the driest regions on Earth. Despite the harsh environment, it still managed to produce fresh water effectively.With around 2 billion people worldwide lacking access to clean drinking water, this device brings hope for a more sustainable and practical solution—especially for those living in arid and remote areas.
