Rather than paying to cool the heat servers generate, some organizations are taking a different approach – and putting all that hot air to valuable reuse. Intel and NetApp are each separately reaping that heat into hundreds of thousands of dollars in savings.“We’ll no doubt continue to see approaches to reusing heat waste evolve. Perhaps, soon, there will be a way to efficiently transform it into power for the datacenter. Even today, though, there’s already a potential ROI, both in terms of economic and environmental benefits,” senior analyst Ted Samson writes in Harnessing datacenter heat for savings. IBM, for its part, is warming a swimming pool outside Zurich with what would otherwise be wasted datacenter heat… Technology Industry
