Toronto, Apr 17 (Canadian-Media): Scientists have developed a box which can convert low-humidity air into water, producing several litres every 12 hours, American researchers said Thursday, media reports said.
According to scientists an estimated one third of the world’s population lives in areas with low relative humidity and in areas going through droughts experience dry air, CBCNews reports said.
The device is currently in the prototype phase and can produce nearly 3 liters of water per day for every kilogram of spongelike absorber it contains, and future versions will be even better, researchers said, Science Journal reports said.
Evelyn Wang, a mechanical engineer at the Massachusetts Institute of Technology (MIT) and co-author of the paper, was confident that new product which captures water from the air could be useful in producing water for remote low-humid and dry areas which have limited infrastructure.
A recent test on a roof at MIT confirmed that the system can produce about a glass of water every hour in 20 to 30 percent humidity, CBCNews reports said.
There were about 13 trillion liters of water floating in the atmosphere at any one time, which are equivalent to 10 percent of all of the freshwater in our planet’s lakes and river, according to an article “This new solar-powered device can pull water straight from the desert air” by Robert Service in the journal Science published on April 13.
Companies like Water-Gen and EcoloBlue had already been producing atmospheric water-generation units that create water from air but this new device can produce water in low-humidity environments using no energy, said Wang.
Co-author Omar Yaghi, a chemistry professor at University of California, Berkeley said this technology opens the door for personalised water.
“This application extends beyond drinking water and household purposes, off grid. It opens the way for use of (the technology) to water large regions as in agriculture,” said Yaghi, CBCNews reports said.
The scientists and developers hoped to reproduce the devices on a large scale and create a formal cost-effective affordable and accessible product, said Yaghi.
