Summary

Story summary

MIT engineers developed an ultrasonic system that extracts clean drinking water from atmospheric water harvesting materials.
It replaces solar heating with high-frequency ultrasonic waves, delivering water in minutes.
Powered by a small solar cell, the device auto-activates when the sorbent saturates and enables multiple daily extraction cycles.
The method is 45 times more efficient than conventional approaches and is published in Nature Communications, signaling use in water-scarce regions.
