Gizmodo Science Fair: A ‘Window’ That Harvests Drinking Water From Desert Air
Researchers have developed an atmospheric water harvester that can extract drinking water from the air, even in the extremely dry conditions of Death Valley. The device, which operates without any external power source, uses a special material called a metal-organic framework (MOF) to absorb water vapor from the air and then release it as liquid water. The MOF material is highly porous and has a large surface area, allowing it to efficiently capture and store water molecules. The researchers tested the device in Death Valley, where it was able to extract up to 3 liters of water per day, even in the arid desert environment. This technology could have significant applications in areas with limited access to clean water, as it offers a sustainable and efficient way to harvest water from the atmosphere.
