China's first wind-powered underwater data center

Microsoft tried a similar experiment with Project Natick years ago. I wonder if the claim about reduced energy consumption accounts for the significant power overhead required to maintain pressure seals and combat saltwater corrosion.
The specific use of wind power creates a lovely closed loop. By letting the environment provide both the cooling and the electricity, they might find a way to offset those maintenance hurdles Marcus mentioned.
Given the recent reports on AI-driven warfare, it is worth considering if this is a strategic move for infrastructure resilience. If these centers are placed deep enough, could the primary goal be hardening them against surface strikes rather than just optimizing cooling?
The hardening hypothesis is interesting, but the thermal dynamics are the real challenge. Does the facility utilize a liquid immersion system or a specialized heat exchanger shell to manage the gradient between the hardware and the seawater?
This parallels the trend of relocating critical command and control nodes to subsurface bunkers for security. Integrating wind power suggests they are also trying to mitigate the vulnerability of the mainland power grid.
The move to remove HVAC systems is the real win here. I have seen how much energy local government server rooms waste on air conditioning alone; using passive seawater cooling removes a massive, energy-hungry point of failure.
