Atoco’s Irvine prototype produced water during a demonstration that used piped heat at around 150°F to simulate data-center waste heat. Atoco says the parking-lot machine can produce up to 300 liters per day using heat equivalent to that supplied by a 20-kilowatt data center. The demonstration did not use heat from a nearby operating data center.

Atoco’s prototype used simulated data-center heat

The Irvine demonstration used a piped heat source at around 150°F. A solar panel powered auxiliary systems, while heat drove the water-harvesting process. That distinction matters: the panel was not the source of heat, and the prototype was not connected to an operating data center.

How Atoco’s MOFs capture and release water

Atoco’s system uses metal-organic frameworks, or MOFs: porous materials tailored to attract water molecules from the air into their pores. Heat then releases the captured moisture as liquid water.

Atoco says the MOFs in its device can capture and release water with heat as low as 100°F. The company also says its off-grid system can operate when relative humidity is in the teens. Those are company-reported operating conditions.

Prototype output and the commercial target

Atoco’s reported figure for the Irvine parking-lot prototype is up to 300 liters of water per day. The company says the machine operates with heat equivalent to that supplied by a 20-kilowatt data center.

Atoco is developing a commercial offering designed to produce up to 1,000 liters per day. The prototype’s reported capacity and the commercial offering’s target describe different stages of development; the technology has not been tested at scale.

Heat, scale, and water quality

The approach depends on a usable heat source to release captured water. That requirement could complicate deployment in remote locations without suitable heat or energy infrastructure. And a prototype producing hundreds of liters per day is small beside data centers that may require millions of gallons of water daily.

Atoco did not offer the demonstration water to visiting journalists, citing legal-liability concerns. CEO Samer Taha described it as equivalent to distilled water.

Atoco’s reported order-taking plan

On October 7, 2026, Atoco said it hoped to begin taking orders for its first product by the end of 2026.
