500 Helsinki Homes to be Heated by Cathedral's Underground Servers

Any company that's ever boasted of its green credentials can shove it in the coal burner, after hearing about Helsinki's Uspenski Cathedral's data center, which will use its overheating servers to warm 500 homes joined by a network of pipes.

Opening in January, the center, run by IT firm Academica, will save $563,000 each year in energy costs, with all 500 homes benefiting from the shared heat presumably saving quite a few Euros too. [Reuters and Fast Company]
