<p>From the wikipedia page:<br>
<blockquote type="cite">The building is accompanied by a series of
artificial lakes: one formal lake directly opposite that
completes the circle of the building, and a further four
'ecology' lakes. Together they contain about 50,000 m³ of water.
This water is pumped through a series of <a
href="https://en.wikipedia.org/wiki/Heat_exchanger"
title="Heat exchanger">heat exchangers</a> to cool the
building and to dissipate the heat produced by the wind tunnels.
</blockquote>
</p>
<p>So this water could definitely be used to cool the data center. I
wonder what that extra heat in the water does to the 'ecology' in
those 'ecology lakes'. <br>

<p>Yes. Something exactly like that! Is that what that

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.<br>

What is the advantage of using salty sea

mineral oil? I have seen on you tube these
guys showing that a pc will <br>

Yes it will be messier to change
