Summary
MIT researchers have developed a new ultrasonic device that dramatically speeds up the process of harvesting drinking water from the air. Unlike existing atmospheric water harvesting systems that rely on solar heat and can take hours or days to evaporate and condense water, this new system uses ultrasonic waves to shake water out of sponge-like materials in just minutes. The technology represents a significant advancement in water harvesting efficiency, particularly for arid regions where humidity is low but present.
Key quotes
· 4 pulledEven in desert conditions, there exists some level of humidity that, with the right material, can be soaked up and squeezed out to produce clean drinking water.
Existing designs rely on heat from the sun to evaporate water from the materials and condense it into droplets. But this step can take hours or even days.
Now, MIT researchers designed a device that quickly recovers drinking water from an atmospheric water harvesting material.
The system uses ultrasonic waves to shake the water out of the material, recovering water in minutes.
