Is cooling water not reusable? Shouldn’t these be closed systems?
Imagine not being able to shower, because AI slop generator machines need that water!

Apparently closed loop systems are not good enough for these kinds of applications, and often instead use evaporative. Which kind of logical, since they’re not running a single factory overclocked GPU with a top of the line desktop CPU, but a cluster of factory overclocked GPUs with a server CPU.

So they build the computing centers in hot areas with water scarcity and make the air hot-humid?

I’m not joking when i say that not using ai is mostly improving my reasoning. Probably, each time I used it, i had to subconsciously offset some thinking to that brainless machine. I’m fine the way I am, i know it’s being propped up as some ultimate solution but my creative output improved too.
We’re probably offsetting some thinking and memorisation to a computer with a complete lack of experience of the real world, and it’s somehow being presented as acceptable. I do n’t think it’s fine.

Could someone explain to me how these data centers use up water? Like it’s it evaporating? What happens to the water? I get the water consumption is very high but is the problem we’re removing it from places that don’t refill or does into the environment mean it’s not wastewater? Please someone help me understand.
RunawayFixer@lemmy.world 1 month ago
Generating power with coal/nuclear/hydro uses water, and since the LLM data centers use power that would otherwise not have been generated, this is one of the ways that they use up water.
For cooling many (most?) data centers use evaporative cooling. That evaporated water could be captured again with a heat pump (reducing the wasted water + recuperating heat for other uses), but it’s Texas, so it wouldn’t surprise me one bit if the data centers have no intensive to be less wasteful.

That is super helpful, thank you.

I doubt those are constantly consuming large amounts of water. hydro just lets it through, and nuclear has chained closed loop systems, and they also let through some after the last loop

They use evaporative cooling in the name of being “green”. Saves a lot of energy, but at the cost of water use.
Auth@lemmy.world 1 month ago
Doesnt this mean the water will come back when it rains? Its not being polluted and rendered unusable is it?

What does a data center need that much water for?
9point6@lemmy.world 1 month ago
To compensate for the fact that Texas is a stupid place to build something that needs a lot of cooling
ZILtoid1991@lemmy.world 1 month ago
Cooling. Even closed loops evaporate a lot.
SomeoneSomewhere@lemmy.nz 1 month ago
Closed loops evaporate stuff all. This is 100% from evaporative cooling towers.
If they were using DX or air-to-water chillers the water usage would be negligible. Like how often you top up the radiator in your car.

don’t be selfishn, Microsoft AI will be used by the whole world and only few people will need this water to shower.

Can’t they just use seawater or use air cooling?
MNByChoice@midwest.social 1 month ago
A lot of the need is due to the heat density of the GPUs used for GenAI. Could they build less densely? Yes, and they likely already are but need to go further. I have seen data centers with racks less than half (I think it was closer to one quarter) populated for energy density issues.
Could they use sea water? Sea water causes more corrosion. (I am uncertain if this data center is close to the ocean.)
Harbinger01173430@lemmy.world 1 month ago
Can’t they just make sub 75w GPUs that require basic cooling?

So assuming the datacenter uses the water for cooling, what happens to the water? Does it just get released as steam?
excral@feddit.org 1 month ago
Of course it would be possible to capture and condensate the steam but that equipment would cost money. If just using more water is cheap and unregulated there is no incentive not to do just so.
ZILtoid1991@lemmy.world 1 month ago
It often just evaporates, since they’re using evaporative cooling.
cantstopthesignal@sh.itjust.works 1 month ago
I just told Chat GPT to implement my code fully and now you can’t shower. Suck it!
DivineDev@piefed.social 1 month ago
So genuine question, how is a datacenter needing water equivalent to showering? When people shower, the water gets dirty and needs to be cleaned. When water is used to cool servers, it gets warm but that should not be a problem, it doesn't need to go through a water treatment facility afterwards (?)
WhiteOakBayou@lemmy.world 1 month ago
They use potable water and they use evaporative cooling.
davad@lemmy.world 1 month ago
I have no idea what the infrastructure setup is like for cooling that data center, but one way of water cooling is to take in cool water and dump the hot water. If you do this in your home, it’s an “open loop geothermal heat pump.” You pull in water from a well, heat or cool the water with your AC heat exchanger, then pump it back into the ground or into the sewer.
sugarfoot00@lemmy.ca 1 month ago
The water may be treated with anticorrosives.
fox2263@lemmy.world 1 month ago
Newer aerated shower heads help with that 👀
ansiz@lemmy.world 1 month ago
I don’t get the news about these data centers guzzling water, where is the water going? If it’s for cooling, but that doesn’t destroy the water…
ZILtoid1991@lemmy.world 1 month ago
Evaporative cooling.
Lord743@lemmy.world 1 month ago
Can’t they recycle it.
Canonical_Warlock@lemmy.dbzer0.com 1 month ago
They use adiabatic gas coolers on their refrigeration systems. Basically there is a perpetually wet piece of media that air runs through before it gets to the refrigeration coils. By running through that wet media you precool the air basically down to the current dewpoint by evaporating water and therefore you’re cooling the refrigeration coils with colder air which leads to more efficient opperation and reduces the size of the gas coolers required. From what I’ve seen a lot of these datacenters are also switching to CO2 based refirgeration systems which are generally better except the low critical temp of CO2 mean that their efficiency starts to drop quickly once the ambient temp gets much above 80F. Using adiabatic coolers mostly removes that shortfall.
