One of the selling points they mention is that they won't need to use any fresh water for cooling.
My understanding was that water-demands on Earth were an overblown issue and minuscule when compared to other uses of fresh water such as watering one acre of farmland.
Not to mention, "used" water is just "warm" water that can then be used again for other purposes.
So are they perpetuating a myth here? Or is water use a bigger issue than I thought?

- welferkj 1y agoIt's not a real issue, but it's truthy enough to generate real opposition to datacenter buildout and catalyze AI hate. So definitionally avoiding it from the get-go might end up being worth it.
- sanex 1y agoIt really depends where they get the water. If they're pumping an aquifer fry and doing evaporative cooling they could be just boiling an entire areas water source. If they could figure out how to use salt water it'd be ideal.
- Geee 1y agoJust run your closed loop cooling through a heat exchanger in sea water. They probably do something like this already.
- itintheory 1y agoYes, pouring more heat into the already warming oceans is surely a safe plan.
- Geee 1y agoThe added heat is so minuscule that it doesn't have any effect on the temperature of the ocean.
- sanex 1y agoI think they prefer to use evaporative cooling though.
- thinkingtoilet 1y agoWell, for one thing you can't eat GPUs, so I'm ok with farmland taking up more water. Also, the "warm" water has already destroyed ecosystems because the data centers are just dumping it. It's a completely solvable issue if we had any common sense regulations.
- heeton 1y agoMinor correction: the water is evaporated. It remains in the water cycle but is removed from the water source for any downstream users.
