HOW MUCH WATER CAN BE PRODUCED FROM DESERT AIR?
MIT researchers have developed a way to produce heat in the desert.
Their technology could be used to provide hydration in dangerously dry areas around the world.
The device is powered by sunlight only, and the researchers said it could eventually be used to provide more than one-fourth of a liter of water per kilogram of metal-organic framework each day.
Pictured is the new device - developed by MIT - that can turn dry air into water in the desert. The technology was first proposed in a research paper last year, and it was met with both optimism and criticism
This output could be much higher if a more efficient material were to be used, the report stated.
The technology operates on a night-and-day cycle using sunlight.
But, researcher Dr Hyunho Kim said, 'continuous operation is also possible by utilizing abundant low-grade heat sources such as biomass and waste heat'.
