While Facebook and Google were transporting servers to cold countries in search of efficient free cooling, Microsoft went the other way and decided to place its data centers under water. The initiative was called Project Natick and, according to the engineers of the corporation, has good prospects. The energy for the functioning of the complex is generated by a turbine generator, and significant savings in maintenance are also obtained. Cooling takes place by itself, because the server is completely placed under water. The company has already successfully tested the first prototype under the name Leona Philpot, which spent 105 days at the bottom of the sea off the coast of California (from August to November 2015). The experiment made it possible to verify the viability of the system. According to the creators, having established the mass production of these modules, in 90 days Microsoft will be able to deliver completed orders to customers. This is faster than 2 years that are required for the construction of a data center on the surface of the earth. Each underwater unit is able to last up to 20 years with the obligatory updating of computer systems every 5 years.
