There’s clearly something going on with the Swiss and hot water: first “extreme jacuzzi-ing” on top of Mont Blanc, and now they’re going to use waste energy kicked out by servers to warm a swimming pool. It’s a simple concept: take the heat from the server room air-conditioners at a new data centre, and direct it through heat exchangers to the water in the town pool. The town, Uitikon, will get a hot pool and all they had to pay for was some of the connecting gear since the heat would otherwise have been vented. Cool! … or rather, hot! Darn eco-friendly too.
