Death Valley in the United States successfully tested: MIT creates a magical artifact of “air to water”, with 160 ml of drinking water per day – Passionategeekz

Passionategeekz June 21 news, technology media scitechdaily released a blog post yesterday (June 20), reporting that engineers from MIT have developed an atmospheric water collector.It can generate fresh water in extreme environments such as Death Valley, California, USA.

MIT pointed out that the global water shortage is becoming increasingly serious, with traditional water sources such as rivers, lakes and reservoirs approaching their limits. To meet this challenge, engineers turned their attention to the water vapor in the air.

The Earth’s atmosphere contains trillions of gallons of water vapor, which, if efficiently captured and condensed, will provide clean drinking water for water-deficient areas.

The MIT team has developed a new atmospheric water collector with a black hydrogel material at its core. This hydrogel has a bubble-like structure that can absorb water vapor in the air. After the water vapor condenses, it flows into the collection tube through the glass surface to form directly drinking water.

The device requires no batteries, solar panels or electricity and operates entirely on itself. In the tests at Death Valley, it produces up to 160 milliliters of drinking water per day, even under low humidity conditions.

Passionategeekz Note: Death Valley is located in the desert valley of California, USA.225 kilometers long, 6-26 kilometers wide, with an area of ​​1408 square kilometers.It is part of the Mojave Desert and is also the lowest, driest and hottest region in North America.have”Extinct volcanoominous nicknames such as mouth”, “Dry Bone Valley” and “Funeral Mountain”.

Unlike other devices that rely on metal organic frames (MOFs), this hydrogel collector solves the problem of salt leakage. The research team added glycerol to the hydrogel, a compound that stabilizes the salt and prevents it from flowing out with water. In addition, the microstructure design of the hydrogel further reduces salt leakage, ensuring that the collected water meets safe drinking standards.

The research team also improved the shape of the hydrogel and designed it into a small dome structure similar to a bubble film to increase the surface area and improve water vapor absorption capacity. In the future, they plan to further optimize equipment through multi-panel design to provide sustainable drinking water solutions for areas with limited resources.
