Sun and a consortium of other businesses are going to lower Blackbox self-contained computing facilities into a Japanese coal mine to set up an underground datacentre, using up to 50 percent less power than a ground-level datacentre.
The coolant will be ground water and the site's temperature is a constant 15 degrees Celsius (59 degrees Fahrenheit) all year, meaning no air-conditioning will be needed outside the containers. This reduces the energy required for the water chillers, used with surface-level Blackbox containers.
The group estimates that up to $9 million of electricity costs could be saved annually if the centre were to run 30,000 server cores.
At least that's the cover story. I think it is a place for a Bond Villain to push up his ranking on Folding@home.
