A new device designed by engineers at MIT could soon help billions of people worldwide access clean, safe drinking water by ...

First, ocean water is drawn up to the device's foam surface through a wicking system. Once the water reaches the surface, it is evaporated by solar-heated plasmonic materials.

During testing, the device was able to capture roughly 2.5 milliliters of water per gram overnight. It then released the water with a 94% efficiency when exposed to sunlight.

The device modifies the natural features of balsa wood to be able to pull water from the environment. According to TechXplore, the technology functioned from 30% to 90% humidity and from 41 to 131 ...

Drip, drip, drip. That’s the sound of Jeremy Cho’s atmospheric water harvesting device extracting humidity from the air to make usable water in Da Kine Lab at UNLV.
