Here's a novel idea: rather than stressing over the choice between solar or hydroelectric power sources to keep that green data center running, just build the thing near a community pool. Apparently that's exactly what's happening in Uitikon, Switzerland, as an IBM-built center erected for GIB-Services AG is using its excess heat to warm a local swimming pool. Put simply, the warmth emitted by the computers will be piped through a heat exchanger to boost the temperature of water used in the neighboring pool, and while the town had to cover some of the equipment costs to make it come together, it'll reap the oh-so-steamy benefits for free.
