- A California startup is developing machines that pull water from the air.
- The systems could produce up to 265 gallons of water per day.
- Researchers hope the technology may help drought-stricken regions and data centers.
- The machines are roughly the size of shipping containers.
- Commercial orders could begin in the second half of 2026.
Friday, May 22, 2026 — For generations, people in the American West have searched for new ways to stretch limited water supplies. Reservoirs, canals, groundwater wells, and recycling projects have all become part of that effort. Now, a new technology is moving closer to reality that sounds almost like science fiction: creating water from thin air.
According to a May 2026 report from the Western Governors’ Association, Nobel Prize-winning chemist Omar Yaghi
is helping lead a startup called Atoco that is developing large machines capable of pulling moisture directly from the atmosphere.
How the Technology Works.
The concept is based on a fairly simple scientific idea. Even in dry climates, the air still contains some amount of water vapor. The challenge has always been capturing enough of that moisture efficiently and affordably.
Atoco’s systems are designed inside units roughly the size of shipping containers. According to the May 2026 report, each unit could potentially produce as much as 265 gallons of water per day by absorbing water molecules from the air and converting them into liquid water.
That amount would not replace a city reservoir or major river system. However, experts say the technology could become useful in places where traditional water supplies are strained, unreliable, or expensive to transport.
Why Data Centers Matter.
The company reportedly plans to market the systems toward drought-affected regions and large data centers beginning in the second half of 2026.
Data centers have become a growing issue in many western states because they require large amounts of electricity and, in some cases, significant cooling water supplies. As more artificial intelligence systems and cloud computing facilities are built across the region, concerns about water demand have also increased.
