China Dominates
Large amounts of water are used for cooling, which puts pressure on water resources and leads to competition with households and agriculture.
TL;DR
- China has the world's only operational, commercial underwater data center in Hainan province, designed for AI computing.
- These data centers are sealed in steel capsules on the seabed and cooled naturally by surrounding seawater, reducing reliance on energy-intensive air conditioning.
- This technology aims to combine high computing power with lower energy consumption and reduced land footprint.
- Underwater data centers reduce pressure on freshwater resources and avoid land use conflicts.
- Potential environmental concerns include localized warming of seawater, which could impact heat-sensitive species, and the risk of leaks or damage.
- There's a possibility that these structures could function as artificial reefs, attracting marine life and aiding ocean research.
