Free advice: The economics don't work out.

    We just need to invent space construction, cheap fusion power, autonomous robotics, improve AI and set up astroid mining first, then it'll be a snap.

    Honestly, it's hard to figure out what the first step in that chain is. If you want to start up industry in space, great, there are lot of potential benefits to that. But where do you start?

    Within the next 50 years I do expect a broad sector of space industry to emerge, but I really can't predict what the first opportunities might be. Still, we can poke fun at it all we want right now, but I suspect a great many people will be working in space 50 years from now.

    Mining raw resources that are more easily availabe on asteroids than on earth seems like the most likely candidate. There are metalic asteroids that have significant quantities of valuable metals like gold, titanium, iridium etc.

    Getting rid of the heat is going to be an issue for that... along with the massive pollution from the many launches required to get this in orbit.

    The heat will just dissipate in the air, and they can launch it at night when it's colder. Science!

    They could build them so that they stay in perpetual dawn or dusk. One edge with the solar panels in the su, the other edge with the cooling fins in the night’s cool breeze.

    Geostationary orbit is far higher than low earth orbit and I would assume following earths twilight zone would not be much better. I do not see why you would either, with reaction wheels you could orient the satellites towards the sun regardless of the relative position of the earth, with the caveat that earth may block the sun which is hard to avoid entirely anyways.

    Also, there is not that much cool breeze in space, famously known for not having vast amounts of air (still have IR-radiation to help though).

    Edit: Probably ate the onion, didn't I?

    I'm pretty sure they're aware of the need for radiators. They've probably designed satellites before.

    Nobody thinks they're incapable of working this out; we think theyre deliberately advertising something dumb that lay people won't necessarily understand is dumb. Replying that they have smart engineers is stupid because no-one denied it - we just don't think they used those engineers to come up with the idea.

    yes but they're not trying to dissipate megawatts usually

    Again, I'm pretty sure they're aware that you need bigger radiators when you're using more energy. This is space engineering 101.

    They'd better not try to sell them to anyone who has access to an engineer, then. Just a single engineer will bring the whole scheme crashing down.

    for starters, at the loads they're running at, they have literally hundreds of gpu failures a day. How do you propose doing that in space?

    Include spares.

    I hope they're reading this thread and taking notes, they probably didn't think of that.

    and the infrastructure and robotics to replace them, of course.

    Assuming 200 nvidia H100 failures a day (conservativo, reality is worse) that's an extra ~340kg of weight you'd need to launch per day. Which is an extra 120 tons yearly.

    So, one Starship launch per year. Doesn't sound like a problem.

    at least two, you can't stuff a rocket full of just gpus, you need something to actually dock and deliver the payload in space. So you need to launch at least 2 rockets (in a non-reusable configuration, so you need to pay for the whole rocket and the launch) to ship a bunch of gpus that are, at best, only 10% as fast as usual.

    Okay, two then. It's still cheap.

    in a non-reusable configuration

    Why do you say that? 120 tons is well within Block 4's projected capacity in reusable configuration. 240 tons is almost within it, even.

    and forget about running 4nm chips in space. shit has to be radiation hardened, which means bigger process nodes and higher energy cost, and lower speed

    Another thing they probably didn't think of. Nobody's run chips in space before.

    they did think of it. lots of people have. I just mentioned what was required. Rad hardened processors are usually 10 to 20 times slower than what we have on the surface

  • source

    So don't use rad-hardened processors, put them in a radiation vault instead. Those become more mass-efficient the more hardware you're putting inside them.

    Really, I assure you the people proposing these things have put more thought and expertise into it than a bunch of random Fediverse commentators.

    Back when the capacitor plague hit I had to manage locating & replacing over 500 motherboards in the datacenter of my then-employer. Imagine if a hardware glitch like that happened in one of these.

    I had some of these bad capacitors blow in my video card, back in the day. I was extremely proud of myself for managing to order some replacement capacitors and soldering them in myself.

    The most impressive part might be that I ordered the right items. I knew nothing about electronics repair at the time, I just wanted to be able to play World of Warcraft again.

    Isn’t it incredibly difficult to shed heat in space since the only real way to move heat is radiation?

    In the (fiction) novel Artemis by Andy Weir, which takes place in a city on the moon, they have a heat management system that seemed pretty cool. They convert heat to light, and radiate the light out into space. Not sure how feasible/scalable that is, but I thought the concept was cool.

    Even if this was an economically sound proposal, the next X45 magnitude solar flare might be a nasty surprise for reliability metrics...
