I think it's currently only available in Germany, but it's a pretty cool idea - cut your energy bills by housing one of the company's servers. From their website: "The innovative heating system from Cloud&Heat Technologies GmbH involves a fireproof safety cabinet that is equipped with servers and installed in the building that is to be heated. With the computing process, the servers generate heat that is fed into a buffer tank. This tank supplies the hot water system and heats the domestic hot water. Additionally, via a centralised air handling system, the waste heat that is generated is used to heat the building."
