    Love the idiot in the article comments saying „the heat is immediately removed into the vacuum of space“. What is the thermal conductivity of a vacuum, genius?

      this place is officially retarded if I bring up the fact that there is such thing as radiation or radiating energy i’ll get called a datacenter lover. you people fucking suck

          The “there is no air in space therefore datacenters in space are a bad idea” crew is not going away. Are you even human?

            Check how many square meters of copper radiators per human you need on ISS and then do the math kwh for a datacenter and you will get more tonnes of material than any material on the hole planet earth and now you understand why it’s your idea that’s removed from any intelligent discourse.

            Or why would I bother educating you. Go and invest in companies building data centers in space, vote for them, idc

        No you’re just confident despite your ignorance. Turning waste heat into electromagnetic radiation is not easy or efficient - 100 to 350W per square meter in current space craft. The sheer scale of radiators necessary in a orbital data centre would dwarf the footprint of the servers themselves.

          See exactly. I bring up the fact that radiation exists because you obviously don’t know what you are talking about and to desperately try to stay right you invent in your head that I am ideologically against you. You need your echo chamber do you jackass?

          I don’t know if you realise this but that doesn’t matter. I am not advocating for anything so you are not disagreeing with me. We are both informing this jackass that thinks because there is no air in space that heat can not be dissipated. This is not a matter of if datacenters are a good idea or not. Bro come on I said it, this place is officially retarded and you people fucking suck.

              Never said it was. But if you want a solution NASA figured it out almost 3 quarters of a century ago. If the cooling solution is the thread that makes or breaks the concept sure you could justify being this irrational I guess or you could find the next better reason to be against data centers in space. Upto you.

                  Cool a material topology problem, so when scientists and engineers figure out how to do it what then? Is your only reason for being against datacenters in space is because you think they cannot be cooled? You cannot come up with any other argument that you could just use instead? Presuming you are picking up their torch math guy?

                    Well, you can’t really come up with a novel material to dissipate faster because the math I presented is actually assuming perfect efficiency. If you understood the math you would have noticed the physical constant governing that process. I never came up with any arguments against it, I am just stating a fact that it would take a 1 megawatt data center a 250k ish square meters of radiating surface.

                    I am against data centers in space for more practical reasons though, space isn’t a good environment to really build anything and we are decades or centuries away from doing anything like it. The data transfer won’t be ideal via microwave transmissions for many of the things you are going to want to use the data centers for. Getting the material itself to space is far fetched and manufacturing in space requires an entire earth bound supply chain and adding the step of launching into space isn’t going to be cost effective at any scale.

                    Data centers they should be smaller, distributed and hooked up to the L3 fiberoptics network and instead of subsidizing mega corporations we should be educating and empowering people to self host hardware they own and control in their own home to build a distributed cloud. I don’t care about data centers in and of themselves or where they are. I care that the capitalist governments are going to squander the capital build out for things I don’t like such as surveillance, military industrial tech and bull shit. Since they operate as a get rich quarterly scheme and not a long term asset for man kind, the build outs are going to be where the land use is cheapest and those all happen to be sensitive ecosystems facing other challenges already, otherwise they’d be desirable and expensive.

        Black body radiation is a real, but it’s an extremely inefficient way to get rid of excess heat. So you’d need huge radiators to get enough surface area.

        Add to this the fact that terrestrial data centers operate at a loss, and there’s no way to run a space based one profitably.

            “Black body radiation” is the physical process by which you “dissipate” (the correct word here is “radiate”) heat in space.

            In space you can’t just have the heat be passed from the radiator to some “substance” that fills space (like on Earth the heat is passed to air or to water that then gets released to the environment) because almost all of space is empty of matter (not exactly: there’s incredibly low density stuff in it, mainly ions, but such low density means pretty much no available mass to sink the heat), so the only way for that heat to leave is the natural physical process of a warm body emitting photons merely because of its temperature (the wavelength of which depends on temperature) which is called Black Body Radiation.

            As others have pointed out, it’s a way less efficient process that dissipating heat by it being passed from the radiator directly to some substance that’s part of the environment (i.e. transmission).

        Please reconsider your use of the “R” word. It is not harmless. People try to say “it just means stupid” but we all know what people that word refers to. They also know this word, and know it’s used in reference to them.

        They don’t deserve it. My wife, for example, used to teach Shakespeare in theatrical classes in the adult day school she worked at. Her student absolutely were capable of learning that and understanding it fully.

        Yeah, language evolves over time. But just as I hope you wouldn’t call a Black person “colored” because that term is currently not appreciated (even though it was the preferred in decades past), I hope you would consider removing the “R” word from your vocabulary as well.

          They’re arguing in favor of AI. They already don’t care about other people, unfortunately.
