Do you mean to suggest that computer hardware does not need to be cooled when it is in space? Or that it is trivial and easier to do this in space compared to on Earth? I don’t understand either claim, if so.

The computer hardware only needs to run enough AI compute to be smart enough to convince Musk that it's working. It should be fine.

Superconductors. Average temperature in space is around 4 K.

Even assuming that this la-la-land idea has merit, the equilibrium temperature at the Earth's orbit is 250 Kelvin (around -20C). The space around the Earth is _hot_.

There are people literally working on accomplishing this. I don’t understand what’s with the arrogance and skepticism.

Edit: Not trying to single out the above commenter, just the general “air” around this in all the comments.

I honestly believed folks on HN are generally more open minded. There’s a trillion dollar merger happening the sole basis of which is the topic of this article. One of those companies put 6-8,000 satellites to space on its own dime.

It’s not a stretch, had they put 5 GPUs in each of those satellites, they would have had a 40,000 GPU datacenter in space.

They're reinventing physics? Wow! I guess they'll just use Grok AI to fake the launch videos. Should be good enough for the MVP.

For the superconductivity idea to work, the entire datacenter needs to be shielded both from sunlight and earthlight. This means a GINORMOUS sun shield to provide the required shadow. But wait, the datacenter will orbit the Earth, so it also will need to rotate constantly to keep itself in the shadow! Good luck with station-keeping.

There's a reason the Webb Telescope (which is kept at a balmy 50K) had to be moved to a Sun-Earth Lagrange point. Or why previous infrared telescopes used slowly evaporating liquid helium for cooling.

Because it's a fundamentally stupid idea. Stupid ideas should be laughed out.

I'm not talking about "stupid because it's hard to do" but "stupid because of fundamental physical limitations".

you do know about the Sun? Earth? and the Moon? where would you get this 4 kelvin?
