Researchers at the University of Texas at Austin have built a jacket that collects water directly from the air and converts it into drinking water. The study was published in Scientific Advances and described by Engadget.
Most existing atmospheric water harvesting technology is large and difficult to transport. The UT Austin team set out to shrink the concept down to something wearable. The jacket uses a specially designed fabric that draws moisture from the air and moves it into detachable harvesting units attached to the garment. Those units are then placed into a foldable collector and heated to produce water safe to drink.
Guihua Yu, one of the study's authors, explained the thinking behind the project. "We wanted to rethink the form of the technology," Yu said. "If the fabric itself can collect water from air, it opens a new direction for personal and portable water access."
Co-author Keith Johnston described what made the design functional at scale. "That transport design is what allows the material to work not just in a small lab test, but in a wearable system," Johnston said.
In testing, the jacket produced between 400 and 900 milliliters of drinkable water per day. That range is roughly 14 to 30 ounces, and the output varied depending on the humidity level of the surrounding environment.
The jacket was the specific form factor chosen for the study, but the researchers noted that the same textile could be used to make other objects, including backpacks and tents, with similar water-collecting properties. The investigators suggested the technology could be especially useful for medical response teams working in remote areas or during emergencies where clean water is scarce. They also pointed to potential commercial uses in hiking and extreme sports gear.
The research came out of UT Austin's materials science program and represents a step toward making atmospheric water harvesting a practical, portable tool rather than a fixed installation.
