The only real advantage is 24/7 power without having to use batteries (or some other power supply at night or when cloudy). The way solar prices are going the problem of suppling power when the sun isn’t visible is a real bottleneck.

Is there an orbit which has 24/7 sun and a visibility to same location?

To say the quiet part out loud, I don't think any serious companies have any intention to build a data center in space. There is no benefit in actually trying this. There is however, benefit in saying you'll do it to advance a narrative and distract from the problems terrestrial data centers are facing to an audience that mostly doesn't understand how heat transfer in a vacuum works.

I always assume, unfortunately, that once companies start to get to a certain point they become strategic, and military applications comes into play. They then probably get special consideration when it comes to funding and access. All of Musk's efforts certainly fit this paradigm.

The real advantage is latency but who really needs that? The military may have some use cases (think remote control of drones and the link between the controllers and satellites) but the use cases are limited

It is far easier to build them at remote places and bunkers (or both). Even at the middle of the ocean will make more sense and provide better cooling (See Microsoft attempt at that).

it is not far easier to distribute content from a bunker than from the space.

Did a not accidentally sneak in there? Because serving data from bunkers is done quite a bit right now.

How do you propose to get 10MW of heat from the computers out to the radiators?

Same way we’ve always done it. https://en.wikipedia.org/wiki/External_Active_Thermal_Contro...

I.e. pumps, just like on the ground.

Datacenters in space have one asymmetrical advantage: FBI cant physically raid them. And with Direct-To-Cell, content delivery satellites in space are unstoppable.

It can be considered as advertising. Like Coca-Cola. Not actually anything new or real most of the time. But keeping the mind-share. Making the company seem like they are on cutting-edge, visionary and futuristic. After all the scam is build on future promises. And not the current day real profits.

Classic misaligned incentives - pretendgineering is far more profitable than building stuff that works reliably and is useful.

We've moved past bullshit jobs to a bullshit economy, which operates by moving money from investors to billionaires and back again, driven by pitch deck thoughts and prayers and implied threats. ("Bail us out or everyone dies.")

I am skeptical as well BUT on the cooling question, which is one of the main concerns we all seem to have, the article is doing a bit of an apples-to-oranges comparison between the ISS and a cluster of small satellites. It cites the ISS's centralized 16kW cooling system which is for a big space station that needs to collect and shunt heat over a relatively large area. The Suncatcher prototype is puny in comparison: j…

In theory rocket launches sound bad, with burning fuels all the way up to the top layers of the atmosphere, but it's not clear right away that we're significantly increasing the "burnt up stuff" vs say, the ~100 tons of meteorites that hit every night.

Arguments re: Methane as a non-renewable resource are of course right, except that we technically can synthesize methane from CO2 + electricity (e.g., terraform industries), but the pollution angle is presented as-is, without a systematic analysis, right?

What's the actual atmospheric burden here?

This essentially says "We dont know"

It probably shouldn't be so hard to find military application for more compute in space. Especially give the global surveillance and communication networks like starlink and intelligence sats.

What better way to cover up such space compute capabilities than the AI madness.

Related" "A City on Mars" (2024) [1] A useful book on why self-sustaining settlements on Luna, Mars, or earth orbit are pretty much hopeless. Remote bases that take a lot of supply, maybe, with great difficulty. The environment is just too hostile and doesn't have essential resources for self-sustaining settlements. The authors go into how Antarctic bases work and how Biosphere II didn't. The worst real estate on Ear…

>"A City on Mars" (2024) I wasn't terribly impressed with this one. I found it mostly just a bundle of vague negativity and insufficient (disingenuous?) use of problem-solving. However if you want to try it then give the rebuttal a fair shake too. https://nss.org/wp-content/uploads/NSS-JOURNAL-Critique-of-A...

"One modern idea that O’Neill did not consider is to move server farms in space, where power is cheap and you can dump heat into space with a black piece of metal."

Hmmm.
