The actual MIT press release has much better information than the Techcrunch article:
The test device was powered solely by sunlight, and although it was a small proof-of-concept device, if scaled up its output would be equivalent to more than a quarter-liter of water per day per kilogram of MOF, the researchers say. With an optimal material choice, output can be as high as three times that of the current version, says Kim.

- Animats 9y agoThat's a desert survival device. Not a useful source of water for anything other than dire emergencies.
- AdmiralAsshat 9y agoArizona air isn't very humid, to my knowledge. I'd be curious to see how much this device can gather in gulf areas. It might be very useful in somewhere like Saudi Arabia, where expensive desalinization plants are pretty much their only source of fresh drinking water.
- nkurz 9y agoArizona air isn't very humid, to my knowledge. I wasn't sure about the numbers either, so I looked it up. The levels were higher than I would have guessed, generally ranging from 30%-50% relative humidity. https://www.currentresults.com/Weather/Arizona/humidity-annual.php https://www.currentresults.com/Weather/Arizona/humidity-annu...
