[+] fallaciousBasis@lemmy.world -7 points 8 months ago (12 children) What part of radiator don't you understand? permalink fedilink source parent hideshow 12 child comments replies: [–] athatet@lemmy.zip 13 points 8 months ago (6 children) What you don’t understand is the size requirements those radiators would need to have to cool an entire data center. permalink fedilink source parent hideshow 6 child comments replies: [+] fallaciousBasis@lemmy.world -9 points 8 months ago (5 children) It's conserved. permalink fedilink source parent hideshow 5 child comments replies: [–] athatet@lemmy.zip 5 points 8 months ago (4 children) Right. Exactly zero understanding on your part. permalink fedilink source parent hideshow 4 child comments replies: [–] fallaciousBasis@lemmy.world -4 points 8 months ago (3 children) 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? permalink fedilink source parent hideshow 3 child comments replies: [–] athatet@lemmy.zip 1 point 8 months ago (2 children) 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. permalink fedilink source parent hideshow 2 child comments replies: [–] BeardededSquidward@lemmy.blahaj.zone 3 points 8 months ago 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. permalink fedilink source parent [–] fallaciousBasis@lemmy.world -3 points 8 months ago 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. permalink fedilink source parent [–] BeardededSquidward@lemmy.blahaj.zone 7 points 8 months ago (4 children) 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? permalink fedilink source parent hideshow 4 child comments replies: [–] anomnom@sh.itjust.works 4 points 8 months ago (3 children) 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. permalink fedilink source parent hideshow 3 child comments replies: [–] BeardededSquidward@lemmy.blahaj.zone 0 points 8 months ago (2 children) There's a difference certainly but do you think the people who seem to be floating this idea know the difference? permalink fedilink source parent hideshow 2 child comments replies: [–] anomnom@sh.itjust.works 1 point 8 months ago* (last edited 8 months ago) (1 child) 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. permalink fedilink source parent hideshow 1 child comment replies: [–] fallaciousBasis@lemmy.world 1 point 8 months ago Radiative cooling is all you got in space. permalink fedilink source parent
