MIT's new water-harvesting tech uses sound waves: Here's how
MIT scientists have come up with a clever way to pull clean water from the air using sound waves instead of heat.
Their new device uses an ultrasonic actuator that shakes water molecules loose from absorbent materials in just a few minutes, using very little energy.
This could be a game-changer for places where fresh water is hard to find.
Faster, greener, and ready for real life
The ultrasonic device works 45 times faster than old-school solar heating and can run on a small solar cell—so it's both quick and eco-friendly.
As researcher Ikra Iftekhar Shuvo put it, "With ultrasound, we can precisely break the weak bonds between water molecules and the sites where they're sitting."
Lead scientist Svetlana Boriskina is hopeful this tech could one day help homes get reliable water straight from the air, potentially making daily needs easier and more sustainable.
