Google uses sea water to cool down Finnish data center

A few years ago, Google pulled out a fat wad of cash to purchase a Finnish paper mill, which now, plays home to a state-of-the-art data center. What makes this one different is the way it keeps cool and calm. The search engine giant is making use of sea water to cool this data center down, using a quarter-mile of seawater tunnels, previously used by the paper mill. The challenge faced however is corrosion issues. Sea-water is known to corrode just about every metal it lays its hands on. Currently, Google is busy working on ways to desalinize the water as much as needed and at the same time reduce the impact caused by this data center on the surroundings.

Yet another environment-friendly data center that shifts a mile away from the usual polluting and environment-harmful policies most data centers adopt, Google has done it again, with yet another planet-friendly initiative.
