    Scott Manley has a video on this:
    https://youtu.be/DCto6UkBJoI

    My takeaway is that it isn’t unfeasible. We already have satellites that do a couple kilowatts, so a cluster of them might make sense. In isolation, it makes sense.
    But there is launch cost, and the fact that de-orbiting/de-commissioning is a write-off, and the fact that preferred orbits (lots of sun) will very quickly become unavailable.
    So there is kinda a graph where you get the preferred orbit, your efficiency is good enough, your launch costs are low enough.
    But it’s junk.
    It’s literally investing in junk.
    There is no way this is a legitimate investment.

    It has a finite life, regardless of how you stretch your tech. At some point, it can’t stay in orbit.
    It’s AI. There is no way humans are in a position to lock in 4 years of hardware.
    It’s satellites. There are so many factors outside of our control that (beyond launch orbit success), that there is a massive failure rate.
    It’s rockets. They are controlled explosives with 1 shot to get it right. Again, massive failure rate.

    It just doesn’t make sense.
    It’s feasible. I’m sure humanity would learn a lot. AI is not a good use of kilowatts of power in space. AI is not a good use of the finite resource of earth to launch satellites (never mind a million?!). AI is not a good reason to pullute the “good” bits of LEO

      Not to mention all that stuff left in space can’t just be brought down safely to reuse/recycle like other materials. So it’s a permanent loss of resources.

        And not just the resources, those orbits are going to be cluttered with slowly-deorbiting junk too. Until we get around to making something that can clean them up, we won’t be able to put anything else there.

    Sun power for data centers? How do they transfer generated energy? Or are satellites themselves data centers? :P

      Indeed, the plan for SpaceX is to literally launch computers into orbit to have orbiting data centers.

      No, I cannot explain why this seems like a good idea to anybody. Beyond, “Elon Musk likes juicing his stock by announcing useless sci-fi plans that won’t come true”

          Don’t think the goal is to get something functional, but to get money for it. The hardware would become outdated in short order even if you could overcome the heating issue.

          He will just raise money in this grift and then run away with it, like literally every other grift he’s ever done. He’s never cared about it being realistic. Note the extreme lack of people on both the moon and mars, despite his promises of a colony in the early 202Xs. Note how his cars still don’t have FSD.

          He’s just a liar.

      They use microwave emitters to “beem” the power to the surface, where it is captured by antennas.

        I’m old enough to have played SimCity and there was a satellite power supply that only sometimes would miss the receiver and incinerate a swath of the city. Good times

    This administration is only going to approve these satellites if they are powered by coal.

    Or if you give them a big fat bribe, either one will suffice.

    While to that apartheid bastard seem to be a wonderful idea of having data away from the prying hands of world governments, as they try replicating cyberpunk sci-fi concept of placing stateless corporate data havens in orbit, current limitations of technology, bad space weather which could fry pricey circuits and worrying problems with space debris makes such a concept less feasible.

      Not a few huge datacentres, a million small ones ~ starlink v2 size and power, mostly solved. There’s 99 problems with this (see Kessler syndrome, radiation, …), cooling isn’t (much of) one.

    SpaceX claims the fleet will orbit the Earth and use the sun to power AI data centers

    I do NOT believe them.

    I think they rather want to use AI to power the sun.

    Lol, either these won’t be able to cool themselves or they will pump out heat straight into the upper atmosphere, which seems like a bad idea (I honestly don’t know enough but I suspect we simply don’t have the data to know what long term negative effects it will have)

    Also just like Starlink this is a really dumb way to solve any problem other than how to inflate SpaceX valuations.

    Now the lie that Starlink is resistant to censorship has been exposed twice (Ukraine & Iran), this is just the test Elon Grift.

      The edges of the atmosphere are either too thin to do any heat transfer, or when the air gets thicker the satellite has friction and quickly burns up.

      This was my first thought, cooling in space is hard. There isn’t a medium for the heat to transfer through, outside of inferred radiation. I could be very wrong on this though

    This idiot can’t even figure out self-driving cars, but we’re supposed to trust him to point microwaves at the Earth’s surface? All so that he can power a technology that no one wants or needs?

    Fuck this timeline.

    I would like to say unlikely, because we have a relatively small orbit band that has 100% sun exposure and this is just a stunt of Musk to foster SpaceX. But with the current administration, who knows.

    I wonder at which point the amount of satellites in orbit would begin to measurably reduce the incident solar radiation on the surface. If we could block out the sun to cool the earth and capture that energy at the same time to do useful work, that’d be pretty cool.

    But this would probably just go to powering orbital datacenters running Grok, so we’re fucked anyway.

      I don’t think blocking out the sun is the answer to global warming lol

      Having lived through 3 partial/total solar eclipses, even a small shift in the amount of light really fucks with the rhythm of the entire environment. Birds stopped chirping entirely at noon last time. We’d just be replacing one form of global disaster with another.

      Not to mention we’d end up fully saturating the available orbital space around earth, causing constant satellite crashes and the complete inability to launch rockets through the mesh and debris. At a certain point the satellites would cease to function entirely through all the trash orbiting earth and at that point we’d have essentially walled ourselves off from ever safely exploring space. It’s a terrible idea all around

    Not a space expert but in v1.5 isn’t the center of mass being unaligned with the center of drag going to cause issues over time?
