Data centers in space are a hilariously bad idea. Where would the heat go? This idea is like the opposite of liquid cooling.

Some guy on hacker news argued they could just use radiators.

Indeed. But it's also a hilariously Musky idea! Some moderate technical competence paired with sociopathy and an ego orders of magnitude too big, and voila, you get Cybertrucks, Hyperloops, Neuralinks, Teslabots, datacenters in space, and all the other garbage the man spews.

I cannot wait for him to one day be hit in the face by reality.

>>alex_y+(OP)
I didn't say it was a good idea, just that if Musk perceives it's a good idea then it makes sense why he would want to combine the two businesses.

>>alex_y+(OP)
Aside from Elon Musk, there are a few other people with a lot of capital aiming to do the same thing. That means, either they are all wrong (possible) or this problem has been solved somehow and the solution itself is not public.

Google and Amazon are doing the same thing. Maybe it is a moonshot (pun intended), but Musk is hardly alone in the push.

Not to mention the huge issues of cosmic rays. Sure, if the lifespan of the satellite is expected to be low, then maybe tolerable. But even then, how would this be financially viable?

Shocked to see SpaceX buy the datacenter in space meme. Where does the power come from? Where does the heat go? Why add (high) launch costs to your buildout capex? Why add radiation as another risk factor to your already-unreliable GPUs? Am I missing something fundamental here...?

Radiators might be a reasonably effective way to reject heat if you can run your AI machines at 1000 K or thereabouts.

I think it's far more likely that he wants to combine his businesses to roll his really expensive, debt-ridden companies into one entity with the company that actually reliably makes money.

>>alex_y+(OP)
Only a person who is high as a kite can think thats a good idea.

Money! Also power source is just solar - not too difficult. I don't think radiation would be too much of an issue either since they're in low earth orbit. Heat is probably the biggest problem. Or manufacturing & launch costs. Pretty silly idea anyway.
