[Beowulf] More about those underwater data centers

[Stu Midgley]

As far as I can tell, they are just using the salt water to reject the heat
to.  How they get the heat from the cpu/hot bits to the water is not
clearly stated...

A passive heat exchanger would make energy sense... but would cost a bomb
in engineering...  maybe direct fluid cooling (asetek) with a
heat-exchanger to the salt water?

Either way, its stupid.  They could just easily pump the cool salt water
from the ocean into a DC, reject heat to it using the same methods... and
pump it back to the ocean.  Since no real delta in height, it would be
efficient in energy.

OR... just use a boat...
