Sun to Create Underground Japanese Datacenter
Kurtz'sKompund writes with word of a Sun project in Japan, one that's taking a somewhat non-standard approach to data center construction. To save on power, heating, and water costs, the consortium is going to be building their center in an abandoned coal mine. The outpost will be created by lowering Blackbox systems into the ground; estimates on savings run to $9 million annually in electricity alone.
Sun to Create Japanese Datacenter where the Sun don't shine.
The temperature in a cave means nothing, unless you take into account the cave's ability to dissipate heat somewhere (water or air moving through the cave). If you go inside a cave that's been at constant 55F for a thousand years and you suddenly heat it with 50 kilowatts of power from your data center the temperature will settle at 255F in a hurry. About the only advantage you get from a cave is a constant supply of really cold water (if sufficient rain that year). Ambient air temperature is irrelevant since usually you don't have a strong draft in a deep cave and static air will heat up pretty quickly.
Sun to create datacenter in the land of the rising Sun.
A couple of examples come to mind.
The Government of Canada marijuana farm is located in an old copper mine in Manitoba. You can't beat the security, which is something mentioned in tfa. http://www.cbc.ca/canada/story/2001/08/02/marijuana_010802.html
A solar neutrino observatory is installed in an old mine in Sudbury, Ontario, Canads. It has the advantage of being impervious to almost all kinds of radiation, except of course for neutrinos. http://www.sno.phy.queensu.ca/
As I look at the other posts, I see lots of naysayers. Well there are at least a couple of cases where old mines have been used successfully for other things.
Whoa. Coincidentally, that's the optimum incubation temperature for Mothra larvae.
For the sake of humanity, let's hope that Sun is factoring this into their cooling calculations.
