10 Awesome Data Centers Across the Globe


#9 Google Data Center, Hamima, Finland

Located directly on the Gulf of Finland, this former paper mill was once upon a time known for its sprawling floor space. It was also the source for inexhaustible frigid water supply for cooling the servers in the facility.

This process consists of pumping the water through a 450-meter tunnel to heat exchangers where the fresh water that circulates within the server area is cooled by seawater before the fresh water is re-circulated. Then the warmed seawater is again mixed with cold water from the bay to cool it to the bay temperatures before it is returned, reducing warm water’s environmental impact.

The facility here has no refrigerator or compressor for cooling the whole system. But employees can enjoy the sauna on the site.
