Supercomputer Cools Off Using Groundwater

gManZboy writes "The Department of Energy is no stranger to supercomputers, and its Pacific Northwest National Lab has proven that it can continue to be an innovator in the field by using what the lab calls a unique groundwater-fed cooling system in the lab's newest supercomputer, Olympus. The novel cooling system translates normal groundwater into big savings for the new 162 teraflop supercomputer, which is being used in energy, chemical, and fluid dynamics research. The setup translates into 70% less energy use than traditionally cooled systems."

Re:Geothermal heat pumps

[squoozer]

We looked into fitting one to our house here in the UK. We were doing a full renovation so it seemed like a sensible time to do it. After talking to a number of firms it became apparent that it wasn't a practical technology for the majority of homes here. We have a fairly large garden by modern UK standards but it was less than half the size required for the heat pump pipes. The only option, therefore, was to sink a number of bore holes. The cost of doing that made the system financially impractical - we were much better off just burning gas. It's a shame because I think the technology has a lot to offer and perhaps one day when there's enough demand there will be enough drilling rigs to push the price down.

Re:What happens after though

The water is in a closed loop. They pump it down into the ground to cool the water, and then back up again to cool the computers. Then it just goes down into the ground again (and again).
