China Powers AI Boom with Undersea wind-powered Data Centers

Amazing stuff! Why not heat up the oceans? What could possibly go wrong!

I am not sure what would happen if this was done on a global scale by dozens or more countries.

"... Many companies have sited their data centers in some of the driest regions of the world, including Arizona, parts of Spain, and the Middle East, because dry air reduces the risks of damage to the equipment from humidity ... Partly to address water concerns, China is now putting a data center in the wettest place there is: the ocean. This June construction began on a wind-powered underwater data center about six miles off the coast of Shanghai, one of China’s AI hubs. ...

Instead undersea data centers use pipes to pump seawater through a radiator on the back of server racks to absorb heat and carry it away. ...

The project’s first phase is designed to contain 198 server racks—enough to hold 396 to 792 AI-capable servers—and is slated to begin operation in September ...

a technology that Microsoft pioneered more than a decade ago under an effort called Project Natick, in which the company sank a shipping-container-sized capsule holding more than 800 servers 117 feet below the surface off the coast of Scotland. After hauling up the pod two years later, Microsoft found that underwater data centers “are reliable, practical and use energy sustainably.” ...

The undersea data center concept seems to have growing appeal beyond China. Countries including South Korea have also announced plans to pursue them, while Japan and Singapore are mulling data centers that float on the ocean’s surface instead. ..."

The underwater data center pictured here was a pilot project off the coast of Hainan. Another, more advanced, one is now being built off Shanghai. Shanghai Hailanyun Technology
