    Isn’t one of the big complaints against data centers is the massive demand on water used for cooling? How are they going to cool these in space which is notoriously hard to cool things down in?

      Tech bros aren’t actually smart people, they’re sociopaths who know how to manipulate people. They have no actual value.

      They would use radiator panels which automatically swivel so they’re edge-on to the sun.

      I think the bigger problems are;

      1. The costs (monetary and environmental) of launching so many new satellites,
      2. Large-scale computing technology is untested in that kind of environment and will likely encounter a number of issues and unforeseen problems (so more launches until they get it right),
      3. Additional radiation will increase errors, so they will require a more robust design with more redundancy than Earth-based systems,
      4. If they’re in a low orbit similar to Starlink satellites (which have an expected lifetime of 5 to 7 years) they will need to be constantly replaced.

      Don’t they put plutonium reactors in space? Have to be able to cool those somehow? Or maybe they are not difficult to cool… I know I have seen pretty massive heat fin stacks on satellites.

      Honestly if they are hyper focused on putting data centers SOMEWHERE this seems like a less bad option… Maybe I’m missing the bigger picture somehow.

        The entire point of those is to produce heat to power a thermoelectric generator. And while most of the heat will be wasted, it is a rather small amount overall.

        A data centre would require massive amounts of energy, most likely provided by solar panel arrays. Then the processors will convert all the energy to heat that has to go somewhere.

          I don’t know the math or the physics, purely speculation and good faith discussion (sorry if I offended anyone by being tepidly in favor of this option lol).

          I don’t disagree with your premise that it will be quite the feat, but I doubt they would be broadcasting the headline unless they thought they had a way to make the math, math.

            Bro, Elmo runs SpaceX and Tesla has been talking for over a decade about how FSD is right around the corner, and it’s still pretty much trash.

            Don’t assume these chuds have actually thought shit through just because they are making publicity around it. Silicon Valley is notorious for lying about capabilities to get investor money, and has been for as long as I can remember. If I had a dollar for every full of shit promise I’ve heard out of these dipshits I could pay for healthcare…

        RTGs do get put out in space, however they aren’t used for everything. If a single rocket experiences Spontaneous Unplanned Disassembly while carrying an RTG, it’s a disaster that spreads radioactive materials.

        The entire point of an RTG is to use the waste heat as power, and if I understand RTG design, the cooling fins are to provide the difference in temperature that thermoelectric modules need to produce power. So there isn’t a ton of heat that it gives off in general.

        Look at the international space station. It has massive radiator panels, and all it needs to do is house humans and the equipment to keep them alive. A lot of bulkiness of space suits is dedicated to heat management.

        The #1 product of data centers is massive amounts of equipment-killing heat. That heat either gets radiated via massive radiator panels, or the space data center cooks it’s own equipment.

        Think about that, though. How much heat does a satellite produce to necessitate large fin stacks? And how much heat does a data center produce?

          Honestly not sure about the math, I was just speculating for the sake of discussion, and a belief that this is slightly less harmful to human life than terrestrial solutions.
