This isn't really true, though? The ISS does it with radiators that are ~1/2 the area of its solar panels, and both should scale linearly with power?

ISS radiators run on water and ammonia. Think about how much a kg costs to lift to space and you'll see the economics of space data centers fall apart real fast. Plus, if the radiator springs a leak the satellite is scrap.

The point of the Starship program is to drop the cost of a kg going to space significantly - this isn't meant to be launched with rockets that aren't fully reusable.

Only people who never interacted with data center reliability think it's doable to maintain servers with no human intervention.

There are a class of people who may seem smart until they start talking about a subject you know about. Hank Green is a great example of this. For many on HN, Elon buying Twitter was a wake up call because he suddenly started talking about software and servers and data centers and reliability and a ton of people with experience with those things were like "oh... this guy's an idiot". Data centers in space are exactly…

Might be why he's also investing in building their own fabs - if he can keep the silicon costs low then that flips a lot of the math here.

Whoa there, space-faring sysadmin. You really want that off-world contract tho?

This is terrible for Space-X. They're doing a great job. Musk has left running it to Gwynne Shotwell, who really is a rocket scientist. Now Space-X has a AI business unit they don't need, a new money drain, and more attention from Musk.

Should have merged xAI into Twitter. A failure there would not be a major setback.

I think there is one more possible framing for this. Recently xAI has been in the news for Groq's revenge-porn-like "undress them" feature, which seems pretty legally questionable. Musk has also been in the news for his own Epstein-related activities. If he can move Groq and X into space, well, there's not very many age-of-consent or revenge-porn laws in space as far as I know, so maybe he'll be able to do some sort…

We also shouldn't overlook the fact that the proposal entirely glosses over the implication of the alternative benefits we might realize if humanity achieved the incredible engineering and technical capacity necessary to make this version of space AI happen. Think about it. Elon conjures up a vision of the future where we've managed to increase our solar cell manufacturing capacity by two whole orders of magnitude an…

> We currently make around 1 TW of photovoltaic cells per year, globally. Doubling every three years; at that rate it would take about 30 years for 1TW to become 1000TW. Whether on not the trend continues largely depends on demand, but as of right now humanity seems to have an insatiable demand for power.

We’re not going to use 100% of our solar panel manufacturing capacity to power space data centers, specifically because everyone else on the ground is so power-hungry. If we’re being generous, it could maybe top out at 1%, which adds another ~20 years to your timeline for a total of 50. I think it’s safe to say this part is bunk (along with everything else about this plan which is also bunk).

As a SpaceX fan, I am saddened by this news. The only reason for xAI to join SpaceX is to offload Elon's Twitter debt in the upcoming IPO.

As an old twitter fan, same. I was hoping elon would lose twitter to the banks in a bankruptcy.
