Building cooling maybe.. Then again in the UK I doubt the need would
be so strong. The building from aerial view is ying/yang so it's
probably just design

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 reject

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. 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.

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?

Likely just a convenient place for a second test unit.
In a way this is just an extension of the idea/product Sun came up
wth
where they put a datacentre in a shipping container with the idea
that
you could quickly get the datacentre where it was needed.
While I wouldn't say this won't fail, I think there is a lot of
attraction to the concept given not just the time lag do build a
traditional data centre (mentioned in the article), but even the
cost
of real estate in many/most places people live these days. Do
you,
for one example, want to pay NYC rents or just throw a bunch of
pods
in the Hudson?
I guess once you accept the idea that we no longer maintain these
datacentres in the traditional way - we now just let hardware fail
in
place and ignore it until it's time to replace all the hardware -
moving to smaller sealed units doesn't seem to strange.
