Wall-e predictions getting closer
spandrew•24m ago
There were a lot of YouTube science-fluencers talking about how dumb this idea was. Google themselves called it a Moonshot (har har).

Curious to see if the experiment changes our understanding of space radiators at a certain scale for non-space exploration purposes.

sdcfgy•19m ago
I suspect it’ll go in the trash like their previous experimental infrastructure ideas did.
tpetry•17m ago
Its running for 15 minutes and then must shut down for a long time to cool down. Thats exactly why those "science-fluencers" said its a dumb idea. This is far away from proving that its a viable idea.
moralestapia•11m ago
Source for that?
kieranmaine•4m ago
FTA:

> The cooling system will only be able to operate in brief spurts of about 15 minutes. After that, the TPUs need to shut down to allow the radiators to catch up.

lubujackson•14m ago
Just call it SkyNet and lean into the evil.

Golden Dome is the name https://en.wikipedia.org/wiki/Golden_Dome_(missile_defense_s...

It's a ground-targeting offensive system to be clear, not just missile defense.

trhway•11m ago
It is 700w of heat radiating by 1m2 at 70C ( ie one GPU can sit on such a radiator) What is not to work ok here?
nine_k•7m ago
No air. No convection, only radiation.
trhway•5m ago
That is what I said.
eximius•19m ago
The reasons against doing this is obvious. Is there any coherent description of why someone would think it is a good idea? And I don't mean, like, delusional reasons, but an actually rational argument for "here is where it might work out and we need to try and measure to find out".
fabian2k•17m ago
I don't think it will even come close to being economically feasible. But the main arguments are that you get a lot more and constant solar power and you avoid permitting/regulations on earth.
MarsZebra•14m ago
Edge computing in space is needed for Golden Dome. Weapons targeting etc...

https://en.wikipedia.org/wiki/Golden_Dome_(missile_defense_s...

It's a multi-trillion dollar program, with Bezos/Musk involvement.

sdcfgy•12m ago
No one is building that. They ran out of money and kit taking Iran on already.

At best it’ll direct a lot of public funds into musk’s and trump’s pockets.

MarsZebra•10m ago
Literally the entire aerospace industry these days is centered around Golden Dome.

You should probably short UFO, SPCX, ASTS, RKLB, LMT, NOC, RTX etc.. if you believe that.

TwelveEyes•14m ago
It still doesn’t make sense to me. Technological progress will likely only accelerate. These will be outdated within 2 years easily, and you can’t even recover the chips. The only benefits are the unlimited power without the bottlenecks on earth, lack of political pressure of course, and the low latency for processing satellite data since it doesn’t need to be sent down to earth. These don’t seem beneficial enough to waste this money. It would be good to hear from someone who knows more about this.
hn_submit•8m ago
Elon lets out a fart and everyone's running after it. This is another misguided attempt to pump-up their share price or give clueless investors the feeling that Google is leading the A.I. pack.

Orbital data centers are a stupid idea conjured up by Musk when he was taking mescaline or ketamine. Anyone with half a brain knows this doesn't make sense.

logancbrown•7m ago
Genuine question: why are there so many people up-in-arms on orbital data centers? Like they have a personally vested interest in ensuring their opinions on failure are correct? There are many people on HN that despise it and say it will not and will never work, but here we are, they are flying them up to space and presumably, will start working soon.
cratermoon•5m ago
Spend the money on something we already know works that will help people today, right now.
hn_submit•4m ago
Soon the musical chairs game will come to a screeching halt. Interest rates are skyrocketing and even a Presidential decree will not make them come down.
cratermoon•6m ago
It's not even a test of an orbital data center. All it will do it determine if and how a Google TPU performs in space.
codeduck•6m ago

Yep. No one that matters and isn’t in the investment hype bubble.

Let me know when Raytheon / BAE / Lockheed Martin / General Dynamics get in on it.

sdcfgy•13m ago
It’s a completely fucking stupid idea in all ways if you throw any engineering rationale at it at all.

Negative on: Risk, cost, thermals, radiation, maintenance, latency, complexity, environmental.

The only win they have is making more outlandish shit to inflate value until it goes snap. One trick pony.

risyachka•8m ago
It needs a single use case to justify its existence. And I am pretty sure it has one. The question is will google reveal it? Probably not.

Even as some sort of failsafe compute for when some meteor hits the earth - already enough for a government to pay 10000x premium for it and it will bring in cash.

Obviously this is not intended to play in the same league as common enterprise datacenter.

sdcfgy•4m ago
That’s even more crazy.

No one is going to give a shit about compute if an asteroid hits us. If we survive it, it’ll turn into a resource war within weeks. We’ll be back to the Stone Age.

The only feasible thing I can see is jurisdiction related and that’s not something we should be encouraging. I mean we’ll just end up jamming data centres from the ground.

jonas21•7m ago
What are the obvious reasons against it? I've heard lots of arguments that cooling will be a hard technical challenge and, given current equipment weights and launch costs, it's uneconomical. And I believe those arguments are valid. But is there an obvious reason this would be impossible?

Lots of technologies start out looking economically infeasible, and it's only by investing in development that you're able to get a few breakthroughs. And suddenly, it's a viable technology.

If they do get the numbers to work out, the benefits seem obvious: 24/7 access to clean energy, not upsetting people who'd rather not have a datacenter next door (or in the same state), and plenty of space to scale up.
