Did we somehow mass build pure lossy evaporatively cooled data-centres in the AI era while I was asleep ? Most of them im familiar with lose at best 3-4% of their water per day due to recovery systems even when they are evaporative or open loop to a lake. Yet nearly everyone I hear talking about this seems to treat it as if they lose 100% of their water loop contents per day as if it’s a matter-antimatter destruction system…

The systems used for LLMs are several times more power-hungry than traditional servers. Like, 50-100kW per rack of B200s.

One can criticize ai data centers but the "water consumption"-argument is by far the least-intelligent one and on track on becoming the same kind of populist urban myth that got Germany cancelling (ie destroying) its nuclear plants in order to... checks notes.... save the world.
