Data centers don’t have “water cooling loops” that are anything like the ones in consumer PCs. To maximize cooling capacity, a lot of the systems use some sort of evaporative cooling that results in some of the water just floating away into the atmosphere (after which point it would need to be purified again before it could be used for human consumption)
It also seems from what I can find like some data centers just pipe in clean ambient-temperature water, use it to cool the servers, and then pipe it right back out into the municipal sewer system. Which is even more stupid, because you’re taking potable water, sending it through systems that should be pretty clean, and then mixing it with waste water. If anything, that should be considered “gray water”, which is still fine to use for things like flushing toilets.
As with everything else, we need the government to regulate it because otherwise the corporations don’t really give a shit.
I would be really surprised if anyone is cooling data centres with city water except in emergency, that’s so unbelievably expensive (could see water direct from a lake though but that had it’s own issues too). I recall saving millions just by adjusting a fill target on an evaporative cooling tower so it wouldn’t overfill (levels were really cyclic, targets weren’t tuned for them), and that was only a fraction of what it’d have cost if we’d’ve used pure city.
In this world, we obey the law of thermodynamics.
Yeah the article is disingenuous at best. There are many things wrong with generative AI, but this is just a lousy approach.
If I make a PC, put in a water cooling loop, and use it to run an LLM - sure, water is circulating, but that water isn’t just vanishing lol.
My friend, you are naive at best if you think AI data centers are using closed loop water cooling. Look up evaporative cooling towers. It’s “consumed” in the sense that it is evaporated.
It consumes the resource of “purified, available water” which is consumed as it is no longer purified or unavailable (if evaporated). The same way nothing ever “consumes” energy, it just makes it unusable.
The Excel spreadsheet that calculates this has so many ‘assumption’ cells.
We need municipal datacenters that can be integrated into the municipal water departments, and municipal electrical grid. Use the hot water to provide ‘on tap’ hot water for local businesses that need it.
It’s almost like these “services” are an unnecessary blight that benefit only those that profit financially from them.
that, is what a service always was and will continue to be, live service games, service jobs, telco service. this isn’t new, it just affects more people

Huh. I run a LLM locally on my own machine. Not looking forward to my next water bill.

Have you checked your computers gallons per hour? I’m thinking of getting an electric myself.
