NVIDIA's warm-water fix for AI's thirsty data centers

Short summary

NVIDIA proposes a sealed warm-liquid cooling system for AI data centers that recirculates coolant in a closed loop, eliminating on-site water consumption and reducing annual water use from millions of gallons to near zero. The design also cuts electricity costs by bypassing power-hungry chillers. However, critics note it doesn't account for water consumed by power plants generating that electricity, so AI's true environmental footprint remains significant.

• •NVIDIA's closed-loop warm-liquid cooling eliminates on-site data center water consumption (down from millions of gallons annually)
• •Design reduces cooling-related electricity costs by ~40-50% by skipping power-hungry chillers
• •Caveat: doesn't account for water used by power generation, so full AI environmental impact remains understated
