Clean and safe water is a limited resource, and its availability depends on local water bodies. Earth’s atmosphere contains a colossal amount of freshwater in the form of vapor, although extracting this colorless, transparent, and diluted gas is challenging. Systems that trap dew or fog and collect the extracted liquid in containers have existed for some time. But in dry areas where there isn’t much dew, special materials like temperature-sensitive hydrogels, metal-organic frameworks (MOFs), or zeolites (crystalline aluminosilicates) can help extract small amounts of moisture from the air and release water when heated. Xiangyu Li’s team at the Massachusetts Institute … Continue reading MIT Innovation Produces 1.3 Liters of Water Daily from Just Air: Transforming Water Scarcity in Arid Regions.
