Liquid cooling?

Yes, there was some talk on /. a while back about putting a server farm up
on the North slope of Alaska... here's the link:
http://slashdot.org/article.pl?sid=01/05/14/159258&mode=thread 

Idea was lots of cooling capacity (especially in winter) and lots of
low-cost natural gas to power the thing.. Problems, however, included
staffing and getting the data traffic to/from the lower 48 states.. (not to
mention the time required for a service call!) 

Interesting idea -- I actually used the idea as an exercise in class last
semester - as a (obviously extreme) exercise in facilities management. Point
was to get them to think about all the infrastructure we often take for
granted..
    
As far as selling the heat generated by our systems... A co-generation
facility off of the computer room? (Hmm.. Maybe, for some of our bigger
beowulfs..) But if your campus buildings have steam heating, well, there
might be something to it..

;-)
