Brian Eno has spent decades pushing the boundaries of music and technology, but when it comes to artificial intelligence, his biggest concern isn’t the tech — it’s who controls it.
data centers are mainly air-cooled, and two innovations contribute to the water waste.
the first one was “free cooling”, where instead of using a heat exchanger loop you just blow (filtered) outside air directly over the servers and out again, meaning you don’t have to “get rid” of waste heat, you just blow it right out.
the second one was increasing the moisture content of the air on the way in with what is basically giant carburettors in the air stream. the wetter the air, the more heat it can take from the servers.
so basically we now have data centers designed like cloud machines.
Edit: Also, apparently the water they use becomes contaminated and they use mainly potable water. here’s a paper on it
Also the energy for those datacenters has to come from somewhere and non-renewable options (gas, oil, nuclear generation) also use a lot of water as part of the generation process itself (they all relly using the fuel to generate the steam to power turbines which generate the electricity) and for cooling.

steam that runs turbines tends to be recirculated. that’s already in the paper.
