MIT researchers develop a device capable of transforming dry air into drinkable water. Device can produce up to 5 liters of water per day, check out!

The search for innovative techniques to solve the shortage of drinking water has led researchers to develop devices capable of capturing moisture from the air, even in extremely dry regions. An example of this innovation is a new technology that uses fins covered with absorbent materials and a copper foil between layers of foam. This approach promises to be an effective and affordable solution for obtaining clean water in arid areas.

Check out the details about the device capable of transforming dry air into drinking water

The foams are coated with zeolite, a commercially available crystalline aluminosilicate. The combination enables efficient results in the provision of fast, drinkable water.

Details about the device capable of transforming dry air into drinking water were published in the journal ACS Energy Letters by researchers from the Massachusetts Institute of Technology (MIT) led by Xiangyu Li and Bachir El Fil. O device means new hope for arid areas and communities with limited access to safe water sources.

After the fins absorb moisture from the air, they are heated so that the device releases drinking water. In proof-of-concept tests, the device capable of transforming dry air into drinking water was equipped with 10 adsorbent fins arranged side by side on a copper base, separated by a distance of approximately 2 millimeters.

This configuration maximizes moisture capture from the air, even in desert conditions with just 10% relative humidity. In just one hour, the fins absorbed moisture from the air and, when the base reached 184 °C, released the trapped water.

Device capable of transforming dry air into drinking water can generate up to 5 liters daily

If the cycle is carried out 24 times a day, the device, capable of transforming dry air into drinking water, can produce up to 1,3 liters of drinking water daily in the adsorbent coating, in air conditions with 30% relative humidity.

Production capacity can increase to 5,8 liters of water per day per kilogram of material used, an amount sufficient to meet the daily needs of several cities in arid regions. This is a volume two to five times greater than previously developed devices.

A The only disadvantage is that the system requires energy to release the water, requiring the base of the device capable of transforming dry air into drinking water to reach 184 °C. However, the researchers guarantee that the device can use waste energy or heat from other systems, such as buildings or vehicles, to operate in a more sustainable way.

According to the researchers in a statement, the work identifies a key opportunity for rapid moisture capture and water collection from dry air, several times a day. With further development, this system could be integrated into existing infrastructure that produces waste heat, such as buildings or transportation vehicles, to provide a cost-effective option for generating drinking water in arid regions.

Other devices that follow the same theme

Another device capable of transforming dry air into water is the Kara Pure, created by Cody Soodeen. This is a drinking water dispenser that promises to revolutionize the way we obtain drinking water. This is not just a response to current water quality concerns, but an anticipation of future needs.

Soodeen, inspired by his experience in a city where drinking water was contaminated with unhealthy bacteria, developed Kara Pure to extract water from atmospheric moisture, transforming it into alkaline mineral water.

This device has the capacity to dispense up to 10 liters of water per day, enriching it with seven rare natural minerals and raising its pH to 9,2+, providing not only hydration, but also purification of the body.
