Helsinki will have the very first natural source of heat for their city infrastructure. According to Reuters the city is close to signing contract with one of the IT companies to lend them the underground anti-bomb bunker as a Data Processing Centre, which will be one of the best places that company with a big amount of servers could ever get.

DPC will be located in a underground location, cold and really just made for this kind of equipment. The special hardware will allow to conserve the heat and direct it to the specially created pipe-shafts to heat up the city during stone-cold Finnish nights. I guess we have now our really true environmental friendly solution for the amount of energy we use with our servers.
