Microsoft’s underwater data centre

Microsoft’s underwater data centre idea plumbs the depths in several ways. The idea is to use cold surrounding seawater to dissipate the heat generated. This is of course low-grade heat, but it is perfectly suitable for the heating of buildings, hot water systems, etc, which adds up to a huge amount of energy use worldwide, especially in the colder parts of the world.

A data centre in Helsinki uses the waste heat in this way, heating a group of adjacent buildings. I would be happy to have a data centre in our basement if it meant no more heating bills. There is a fibre optic cable in the street outside, so there is no need for an underwater cable.

What are Microsoft engineers thinking of?
