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.

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…

Re: xAI joins SpaceX
#654Should have merged xAI into Twitter. A failure there would not be a major setback.
Re: xAI joins SpaceX
#655I 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.

Re: xAI joins SpaceX
#660As 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.
