Large technology companies such as Google, Facebook and Microsoft have to constantly expand their server rooms not only to keep growing their customer data, but also to offer more and more cloud services. The problem, however, is the issue of cooling them, so Microsoft is working on a project called Project Natick, which aims to build server rooms under water.

Gigantic server rooms, consisting of thousands of computers, produce enormous amounts of heat. Delicate electronics does not like high temperatures, so it has to be cooled, and it generates enormous costs. So technology companies are looking for different solutions to provide cheap cooling, and that’s why Facebook built one of these under the Arctic Circle, so that ordinary air is used for cooling.

However, Microsoft has developed a slightly different cooling method. The company, which already owns more than a hundred server rooms scattered all over the world, is planning to go down with them now. Engineers have developed a concept for underwater servers located on the ocean floor and enclosed in sealed capsules, which are naturally cooled through water. Capsules with land would connect properly reinforced optical fibers for data transmission.

What’s more, such a solution would not only cool servers, but also power them, using marine-wave energy systems. And the added advantage of such an idea would be to reduce data delays because containers would be close to residential areas.
