Do these cooling systems need fresh water or does salt water work?
salt water cooling systems are more expensive
IMO evaporative cooling should be illegal at a certain scale. Water is valuable.
The really hilarious thing is evaporative cooling (that takes so much water) is simple penny pinching over a closed loop system. That’s all.
…Yet Bezos and Musk are talking orbital datacenters?
Pick a lane?
All that evaporating water is gonna trickle down eventually. Just like the money.
I don’t know if I can take them trickling on me much more than they already are.
What’s going to be in the water when it gets down there?
How many golden showers does Trump own?
how’s an orbital datacenter going to cool itself?
Because it’s cold in space, of course /s
To answer your question, it’s very hard at that scale/temperature: https://projectrho.com/public_html/rocket/heatrad.php
Imagine how good water could evaporate in space!
Water in a vacuum broke my $500 Dyson and I’m still pissed about it. I should have just got the $80 garbage from Target, and if it breaks I buy a new one. Which is so wasteful.
Not really, no. It saves a shitload of electricity, which with current technology means not spewing as much CO2 in order to generate that electricity.
See this comment for math and specifics: https://lemmy.world/post/38090104/20233592
But the TL;DR version:
-
Launching anything into space is heinously expensive. And CO2 emissive.
-
With very generous math, you’d need a radiator like a mile across to cool a space data center, but practically? Larger.
-
Datacenter hardware is unreliable and goes obsolete quickly, and any kind of maintenance in space is basically cost prohibitive.
-
There are other smaller yet still crippling engineering challenges, like bit flips from radiation (which gets move severe as lithography shrinks; look up Nvidia’s research on this), assembling large structures in space reliably, cooling loops for such gigantic structures, and extremely difficult/expensive networking (with distinct issues in LEO or geosynchronous).
And most of all… Solar is dirt cheap on Earth, compared to that.
So is just sticking a pipe in the ground for a geothermal loop, or ambient radiative cooling. We literally have tons of mass to dissipate heat into for free, instead of having to radiate it thermally, yet that’s too expensive for ground data centers, apparently.
That’s the joke.
It’s like saying “air conditioning is difficult” and proposing “I know! Let’s live under the Antarctic ice sheet!” That’s not hyperbole. It might be more practical, actually, as getting mass there is waaaay cheaper…
I hate that the anti AI stuff is 90% idiotic planning permission and capitalism, 5% “The idiots making this put no effort into it” and 5% “I just don’t like it, yuck”.

Sorry 😭
You may just have the perfect Lemmy name! That is all.
May many respiratorially-challenged small dogs bless you, my child ✋
This is the respiratorially-challenged small dog that regularly blesses me by snoring like a freight train. Can be awkward on conference calls if I forget to mute.
They’re so precious! 🥺
Absolutely!!!
❤️🐶
Also Coca Cola has a factory in Atarot, Occupied Palestine
Boycott Israel means boycott Coca Cola
Easy, I didn’t want to buy coca cola products anyway
My girlfriend is Palestinian. She was born and raised there, and lived there until about ten years ago when she came to the USA. I totally get what you are saying, but even she has a Coke every once in awhile. I’m not sure what to think about that!
How dare you!? Think of the Investor’s Money! Mega yachts don’t buy themselves!
Why are making yourself “clean” when that water could be used to generate profit making?
Cat: can’t you just lick yourself, stupid human?
Any reason the background is Mr. Rogers house?
Not the creator, but Im assuming its the same reason for kitty kat, comfortable imagery lures us in for the text to smack us with some uncomfortable (honestly scary) realities.
But remember only you can save the environment by saving water!
Used to be agriculture was using 98% of the water, but we were supposed to take short showers and not flush our toilets. I guess now it’s data centers.
