Microsoft chose to place the data center in Europe off the shore of Orkney, a major center for renewable energy research, to try and determine if placing a data center under water could boost energy efficiency. It often costs huge amounts of money and consumes lots of power to keep a data center cool. Microsoft is testing the theory that the cold ocean
“Additionally because there are no people, we can take all the oxygen and most of the water
The data center is placed in a cylinder that was made by shipbuilder Naval. The undersea cable was developed by the European Marine Energy Centre (EMEC), a Microsoft partner in the project. EMEC’s presence was one of the major factors that led Microsoft to choose the Orkney location. Some are concerned that sinking data centers could warm the water nearby, but Microsoft dismisses that concern.
Cutler says that any warming will be very minimal. He added, “the water just meters downstream would get a few thousandths of a degree warmer at most.”
