> Everything about operating a datacenter in space is more difficult than it is to operate one on earth
Minus one big one: permitting. Every datacentre I know going up right now is spending 90% of their bullshit budget on battlig state and local governments.
But since building a datacenter almost anywhere on the planet is more convenient than outer space, surely you can find some suitable location/government. Or put it on a boat, which is still 100 times more sensible than outer space.

More convenient. But I'm balancing the cost equation. There are regimes where this balances. I don't think we're there yet. But it's irrational to reject it completely.

More corrosion. And still, interconnects.

Surely given starlinks 5ish year deorbit plan, you could design a platform to hold up for that long... And instead of burning the whole thing up you could just refurbish it when you swap out the actual rack contents, considering that those probably have an even shorter edge lifespan.
Starlinks are built to safely burn up on re-entry. A big reusable platform will have to work quite differently to never uncontrollably re-enter, or it might kill someone by high velocity debris on impact.
This adds weight and complexity and likely also forces a much higher orbit.
If you think there is no papework necessary for launching satellites, you are very very wrong.
> If you think there is no papework necessary for launching satellites, you are very very wrong
I would be. And granted, I know a lot more about launching satellites than building anything. But it would take me longer to get a satellite in the air than the weeks it will take me to fix a broken shelf in my kitchen. And hyperscalers are connecting in months, not weeks.
Swear that fella is like the Elon Musk of HN - when he talks about subject outside of his domain he gets caught out.
> when he talks about subject outside of his domain
Hate to burst your bubble. But I have a background in aerospace engineering. I’ve financed stuff in this field, from launch vehicles to satellites. And I own stakes in a decent chunk of the plays in this field. Both for and against this hypothesis.
So yeah, I’ll hold my ground on having reasonable basis for being sceptical of blanket dismissals of this idea as much as I dismiss certainty in its success.
This is a huge one. What Musk is looking for is freedom from land acquisition. Everything else is an engineering and physics problem that he will somehow solve. The land acquisition problem is out of his hands and he doesn't want to deal with politicians. He learned from building out the Memphis DC.
Maybe, but I'm skeptical, because current DCs are not designed to minimize footprint. Has anyone even built a two-story DC? Obviously cooling is always an issue, but not, directly, land.
Now that I think of it, a big hydro dam would be perfect: power and cooling in one place.
Skepticism is valid. The environmentalists came after dams too.
He "learned" by illegally poisoning black people
> an engineering and physics problem that he will somehow solve
no he won't
What ? This is Hacker News man. Talk substance. Not some rage baiting nonsense.

So freedom from law and regulation?
Well let's face it. Not all law and regulation is created equal. Look at Europe.
So why does he not build here in Europe then? Getting a permit for building a data center in Sweden is just normal industrial zoning that anyone can get for cheap, there is plenty of it. Only challenge is getting enough electricity.
I meant Europe is an example of how not to do regulation. The problem you just mentioned. If you get land easily electricity won't be available and vice versa.
I mean, you don't have zoning in space, but you have things like international agreements to avoid, you know, catastrophic human development situations like kessler syndrome.
All satellites launched into orbit these days are required to have de-orbiting capabilities to "clean up" after EOL.
I dunno, two years ago I would have said municipal zoning probably ain't as hard to ignore as international treaties, but who the hell knows these days.
> you have things like international agreements to avoid, you know, catastrophic human development
Yes. These are permitted in weeks for small groups, days for large ones. (In America.)
Permitting is a legitimate variable that weighs in favor of in-space data centers.
that may have been the case before but it is not anymore. I live in Northern VA, the capital of the data centers and it is easier to build one permit-wise than a tree house. also see provisions in OBBB
What counts towards a bullshit budget? Permitting is a drop in the bucket compared to construction costs.
> is spending 90% of their bullshit budget on battlig state and local governments
Source? I can't immediately find anything like that.
Parent just means "a lot" and is using 90% to convey their opinion. The actual numbers are closer to 0.083%[1][2][3][4] and parent thinks they should be 0.01-0.1% of the total build cost.
1. Assuming 500,000 USD in permitting costs. See 2.
2. Permits and approvals: Building permits, environmental assessments, and utility connection fees add extra expenses. In some jurisdictions, the approval process alone costs hundreds of thousands of dollars. https://www.truelook.com/blog/data-center-construction-costs
3. Assuming a 60MW facility at $10M/MW. See 4.
4. As a general rule, it costs between $600 to $1,100 per gross square foot or $7 million to $12 million per megawatt of commissioned IT load to build a data center. Therefore, if a 700,000-square foot, 60-megawatt data center were to be built in Northern Virginia, the world’s largest data center market, it would cost between $420 million and $770 million to construct the facility, including its powered shell and equipping the building with the appropriate electrical systems and HVAC components. https://dgtlinfra.com/how-much-does-it-cost-to-build-a-data-...
Yeah, I was trying to be nicer than "you're making it up" just in case someone has the actual numbers.
> Source? I can't immediately find anything like that
I’ve financed two data centers. Most of my time was spent over permitting. If I tracked it minute by minute, it may be 70 to 95%. But broadly speaking, if I had to be told about it before it was solved, it was (a) a real nuisance and (b) not technical.
