Placing data centers underwater not only helps keep their contents cool, but also has logistical advantages. Microsoft points out that half of the world’s population lives within 200 kilometers of the ocean, making subsea systems potentially easier to deploy when extra capacity is needed. The company also believes that if it can mass produce the capsules it could set them up in just 90 days — much quicker than the two years needed to build a data center on land. Engineers involved in the project even believe that one day, subsea data centers might be able to power themselves using underwater turbines or tidal power to generate electricity.
