This Device Pulls Water From Thin Air—Even in Death Valley

Summary
A new device developed by MIT researchers is capable of extracting water from ambient air, even in the world’s driest regions, according to testing in California’s Death Valley.
The device is described as being like a “sandwich with a layer of hydrogel in the middle”.
One side of the hydrogel is exposed to the air and moisture is absorbed overnight.
This captured moisture is then released during the day as water vapour, when sunlight powers a cooling effect on the device.
The research team believes that the technique could be used to provide drinking water in regions that suffer from water scarcity.
It is also cost-effective, making it a potential solution for providing affordable drinking water at a family scale, the researchers added.
