Yes. Something exactly like that! Is that what that pond is used for? I
would expect that is much larger than what is needed for a typical data
center.

Something like this perhaps?

As far as I can tell, they are just using the salt water to

A passive heat exchanger would make energy sense... but would

(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.
The issue with this would be the increased maintenance cost of the
equipment pumping the salt water to the the DC, do to the
corrosion from the salt water, and overall 'dirtiness' of the
saltwater. A better approach would be to have a closed loop of
treated freshwater going from the data center to the a heat
exchanger submerged in the sea. This should reduce maintenance
costs for the system.
Honestly, though, I think most of this is moot. With
direct-contact liquid cooling and warm-water cooling, I think for
most data centers, cooling to ambient air should be adequate. For
places where that isn't enough, I would think a shallow, man-made
cooling pond on premises would be an adequate heat sink, without
having to go all the way to the ocean. By keeping it shallow, at
night when it cools off, the pond could dump a lot of its heat to
the atmosphere.
OR... just use a boat...

Probably a stupid question here,
What is the advantage of using salty sea water lets say over
for example
mineral oil? I have seen on you tube these guys showing that
a pc will
still run in a fish tank and all components submerged in
mineral oil?
Yes it will be messier to change components but would the use
of mineral
oil be more efficient?
