Overestimate the gains and potential, underestimate the cost.
Typical corporate fads.
Good thing we aren’t running out of fresh water or anyth-

Fuck.
Yeah it’s not good.
I live in an area with normally lush rivers and lakes, rich forest full of life. We’re going on like day 90 of drought conditions. I can’t even light a candle without starting a fucking forest fire.

“Running out of fresh water” narration is a complete lie. I don’t know why, but these articles are implying its like oil that will run out some day. No, fresh water is a manufacturable good. Worst case scenario it gets more expensive as more of it needs to be produced out of salt water ect.
Dumbo I think what people mean is that demand will exceed supply, and as a result lots and lots of people will die of thirst. Water isn’t something anyone can do without.
that demand will exceed supply
You think in terms of fixed supply and fixed manufacturing capacity - but this isn’t the case. Production can be expanded as demand grows
Production can be expanded as demand grows
Lol. You must really think that you’re smarter than the whole field of hydrology and civil engineering, huh?
You do understand that the more expensive it gets, the less people can afford it, right? That’s basically the same as running out. Sure, you can desalinate the whole ocean if you want to spend the resources on it. No one is suggesting that there will one day literally be no more fresh water within the foreseeable future. That doesn’t really matter to the farmers in developing countries that can’t afford to irrigate their fields and thus can’t feed the people there.
And then there’s the fact that desalination is a huge environmental disaster.

the more expensive it gets, the less people can afford it
You know, all these arguments avoid answering the question about how much more expensive water could be. And I suspect the general answer is: not much. Mass producing fresh water is well understood process. It’s also a potential source of sodium for sodium-ion batteries, cheaper alternative to lithium-ion.
And then there’s the fact that desalination is a huge environmental disaster.
I’m fully aware of that - what’s missing there is proper regulation by local governments, preventing excess salinity of water dumped back to the ocean
Where are you gonna get the energy to desalinate water from? What about areas that are thousands of kilometres from the ocean?
Where are you gonna get the energy to desalinate water from?
From the same sources as with the energy needed to manufacture everything else. The demand for electricity has grown year by year for decades, and we haven’t run out of it.
What about areas that are thousands of kilometres from the ocean?
Regular logistics as with any other good
And how will you supply that energy, while also supplying these absurdly energy intensive LLMs and cutting CO2 emmissions?
Yes, the demand has grown year by year for decades and look at the climate catastrophe it has brought us!
Climate is a separate issue. You can supply green energy, nuclear, or burn fossil fuels. Say what you want, but as far as energy production goes, free market keeps delivering since decades.
And it just happens, that regions suffering from the biggest fresh water deficit also happen to have good conditions for solar energy production.
A big consumer in the fresh water market is agriculture. Whenever articles talk about demand exceeding freshwater supplies, it’s referring to agriculture demand, which usually draw from dams, rivers, or lakes.
City water treatmant plants also usually start with pulling water from a river or water reservoir.
The costs with these consumers suddenly spinning up a saltwater or other advanced purification plant, that could perhaps function without a large freshwater reservoir, is prohibitively expensive. Especially for developing countries, where agriculture could be a large part of the economy
It’s not in a closed loop?
No, the water is evaporated as part of the cooling process.
Well that’s a stupid design.
That’s physics. For a closed loop system, the cooling has to be done with air, which is less efficient and that doesn’t work so well in say Texas in summer.
Making it a stupid design, yes.
Edit: putting your massive heat generating data center (beyond what most DCs will do) in support of AI in Texas is stupid.
Closed loop systems absolutely have other options in design, which ive mentioned in another comment chain.
As terrible as they are as companies, meta, apple, and others have made much more appropriate decisions - like locating their big load DCs in cold climates, partnering with the locale to make use of the heat being generated, removing the need for power to be used to perform those tasks - making them not only efficient designs, but compared to putting a DC in Texas like a dipshit (or LA, or NV, or anywhere else with a hot climate), makes the whole thing better for the environment.
Yes, its a stupid design.
