Cooling AI Data Centers — The Nitrogen Advantage: Lessons from Project Natick

Terrestrial data centers are under fire for consuming up to 9 liters of water per kilowatt-hour, but the solution may lie at the bottom of the ocean . This video reviews Microsoft’s Project Natick, where a subsea data center achieved a Power Usage Effectiveness (PUE) of 1.07 and a perfect Water Usage Effectiveness (WUE) of exactly 0 . We analyze the shocking data showing that subsea servers are 8 times more reliable than land-based counterparts . This gain isn't magic—it’s the result of a dry nitrogen atmosphere that eliminates oxygen-induced corrosion and a "lights out" environment that removes human physical intervention . Learn how submarine heat-exchange technology is redefining sustainable compute .
