What would you do to cool off your computer? Probably shut it down for a while or keep it below a fan. But will you put it inside a refrigerator? Well, if your computer receives status updating, picture posting and wall writing from nearly 800 million users everyday, you might!

That is why the giant social networking site, Facebook, announced that they are building their new eco-friendly server farm in Lulea, a city within spitting distance of the Arctic Circle and averages 35 degrees Fharenheit year round. The cold air will serve as a natural air conditioning system, cooling the server farm, which spans 175,000 sq ft over three buildings. Even with the Arctic wind, cutting down the energy bill, it would still take around $75 million annually to operate!
