      What’s going to be performing convection to dissipate heat from the radiator in a manner to support the heat generated by an AI data center?

        Obnoxious as he seems to be, he’s actually right, there will be no convection, but they’d radiate heat in a vacuum, by IR IIRC.

          You’d need an enormous radiator to move the heat a data center puts out. Not even all the billionaires put together could afford that.

            Sure, the idea is as bad as solar roadways. It’s actually kind of impressive to come up with an idea that bad.

          To do that they’d have to be filled with something other than something water based to be able to do that over a large area which would require constant maintenance to do so. It’s not easily feasible and I doubt people who want to do this or defend it realize that. I have to look it up but it takes Anhydrous Ammonia to perform that in the ISS. Like this is a bad idea and it fries my brain people trying to defend this.

            Yeah as I have already said, it’s kind of impressive how bad the idea is, I mean how can it be worse…

          What you don’t understand is the size requirements those radiators would need to have to cool an entire data center.

                Zero effort shit post. Cool.

                Do you ever make posts that demonstrate what your opinions are or what your own thoughts are or do you just like to talk about other people and put them down cuz it makes you feel better?

                  My opinion and thoughts: dunking on idiots online brings me joy.

                  So I guess the last one I suppose. If I just had to pick one.

                    They honestly come off as that sophomore in college that had a single class on something so are going around talking about it smugly. They complain about zero effort shit posts when they do the same thing.

                    You really don’t seem particularly bright. So I did the math, just to double check.

                    A 1 gigawatt datacenter radiating at 100C would need a square kilometer in radiator surface area to sufficiently reject/emit the heat.

                    But then you need energy. With solar panels you’d need 2-3 sq km to sustain 1 GW.

                    So… The math checks out. I don’t understand your arguments from ignorance.

          Tell me you don’t know how radiators actually work without telling me. They dissipate heat via convection through the air surrounding them or gasses in general. What does space lack a significant amount of?

            Yeah so there is some confusion here. The are radiators on cars or in houses, but those are more accurately heat exchangers. Then there are things like heat lamps, which are really IR radiators that convert electricity to infrared light that feels hot.

            Most of the heat you feel at a camp fire is radiant from the flame, unless you are down wind and feeling some convective heat, but most of that heat goes straight up with the smoke.

                Hard to say, but they’ve been using resistive radiative cooling In space a long time.

                Also a tech ingredients made a neat video about building one and radiating heat out into space from the ground. It was cool to see what happened when it was cloudy and stopped working.
