Device creates drinking water from desert air

A year ago, MIT’s research team presented its idea of ​​building a device that can capture even the smallest traces of moisture in the atmosphere of an anhydrous area and turn it into drinking water.

It is understandable that the existence of such a device would be literally a … manna from the sky for people living in areas that are either not easily accessible to drinking water (eg desert areas etc) or live in areas where climate change has turn into arid.

The idea of ​​the researchers, at least as they had presented it, had unfavorable criticism and intense controversy from the scientific community. However, the MIT researchers did not disappoint, on the contrary. They came back with a strong and arguing that, taking into account the observations made to them, they modified their original idea of ​​how this device would work and re-present it.

In addition, the researchers say they created a prototype system that, in their experiments, has shown that it can produce water from the humidity of the air and even make it in the most difficult conditions. In recent years, some systems have been developed to produce potable water from air humidity, but to achieve this, moisture levels must be particularly high, and in addition these systems consume a lot of energy to make the conversion.

MIT researchers argue that the device they built can create water from a sample of air that contains only 10% moisture while not consuming large amounts of energy to succeed with their new publication in Nature Communications. The researchers report in their publication in Nature Communications that the device is based on the use of so-called metal-organic solid structures (MOFs, Metal Organic Frameworks). These materials have garnered interest because of their promising applications in fields such as selective gas adsorption / storage and catalysis.
