Solar-Powered Device Makes Drinking Water Out of Thin Air
This could benefit people in arid climates and water-starved regions.
Scientists have created a solar-powered device that can get drinkable water from air in the desert. If future space travellers visit a dry desert planet and need to find a drink, it's possible they could one day use a similar device there, too, but in the meantime, something like this could be a huge help to water-deprived people who live in arid climates.
The device, which looks a little like the EG-series power droid from Star Wars, uses a custom-built metal-organic framework (MOF) to seek out water, even in dry climates with humidity as low as 20 per cent, and trap it in vapour form. It's reported in the journal Science.
