[Beowulf] More about those underwater data centers

[Stu Midgley]

putting data centres in the ocean is complete rubbish.

The most stupid and expensive exercise I've ever heard of.

Have they heard of a pump?

Heat-rejection to sea water is a good idea (rather than air) and will be a
whole heap more efficient... but you don't need to submerge your DC.  They
still need to get the heat off the cpu's to the sea...  that's where all
the real issues are.
