Nautilus Data Technologies and Reston, Va.-based Bechtel are collaborating to build data centers that are expected to use as much as 70 percent less power for cooling and eliminate the consumption of drinking water.

Nautilus' data centers support the energy-intensive servers needed for artificial intelligence and machine learning applications. The company’s Total Resource Usage Effectiveness technology is a closed-loop water cooling system that uses naturally cold water to keep server racks cool. It combines industrial and maritime cooling methods.

The system from Pleasanton, Calif.-based Nautilus uses naturally cold water from rivers, lakes or bays and returns all of it to its source after use. The evaporative cooling systems currently used by data centers typically consume large amounts of drinking water.
