Portable freshwater harvester could draw up to 10 gallons per hour from the air
For thousands of years, people in the Middle East and South America have extracted water from the air to help sustain their populations. Drawing inspiration from those examples, researchers are now developing a lightweight, battery-powered freshwater harvester that could someday take as much as 10 gallons per hour from the air, even in arid locations. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
