The researchers solar energy A powered device has been built which can produce several liters of air in a day Water Able to achieve.
Manufacturer of this device Saudi Arabia According to a team from the King Abdullah University of Science and Technology (KAUST), a new technology that works without external help can make life easier for people living in dry areas.
The system works in a two-stage cycle, which first separates water from air using an absorbent and then extracts it inside a closed chamber using heat from sunlight. .
A two-phase system is usually moved from one circuit to another by hand.
However, in new technology there is no need for such intervention, rather this work will be done automatically.
Kaiji Yang, who led the research, said: ‘We were initially inspired by observing natural processes.
‘Specifically how plants efficiently transport water from their roots to their leaves through special structures.
“Bridges used for mass transfer in our system will play an important role as a link between the ‘open part’ to capture atmospheric water and the ‘closed part’ to produce fresh water.”
This system can produce two to three liters of water per square meter per day that can be used for drinking or farming.
Researchers have shown that this water can be used to irrigate Chinese cabbage and desert trees.
Automated techniques work continuously without human intervention. No maintenance was required to run the system for several weeks during testing.
Operational costs are also reduced by the materials used in the system, which include air-absorbing fabric and salt and a plastic frame.

According to KAUST researcher Qiaoqiang Gan: ‘We chose this material because of its cheapness and availability. So we hope that the costs of its widespread use in low-income areas are affordable.’
The device is described in detail in a study published in the journal Nature Communications, titled ‘A system to harvest water from the atmosphere using solar energy for independent freshwater production and irrigation.’
The development comes at a time when there is a flood of emerging technologies for water harvesting.
These technologies have emerged due to water scarcity issues due to climate change.
In June, scientists at the Massachusetts Institute of Technology (MIT) introduced a new device that can extract drinking water from the air using water-absorbing ‘wings’.
Last month, the US space agency NASA unveiled a new spacesuit design that can turn urine into drinking water in less than five minutes.
