>>545480953hes just mad because talarico about to dunk on his ASS
The heat needs to be radiated out somehow it's not an energy free solution at all plus you need to harden it for space radiation
>>545480953Wouldn't the best way to cool in space involve cyclic compression and decompression
>>545480953it's funny that a random guy posting on twitter is more educated and intelligent than the monkey that owns it. elon is a hobo and his wealth is completely undeserved
>>545480953>at least he is a good engineer Lmao why would somebody think this? Musk doesn't engineer anything. He pays people to do that. He's not Tony Stark.
>>545480953Elon's right to call him retarded. Jan's right to say that a vacuum is an excellent insulator that's not the problem. The problem is that he called Elon an engineer, and said that Teslas are great cars. Teslas are unreliable deathtraps and Elon is a conman.
>>545480953No he's insulting him for being the midwit of all midwits and trying to tell the guy who runs the company which singlehandedly builds and manages the highest number of heat generating orbital data processing and transmission satellites in the world that what the project they've been successfully implementing for almost a decade can't work because "umm ackshually space is an insulator." Because of starlink, spacex in all likelihood has the most qualified group of engineers and technicians on the planet to opine on the viability of orbital heat rejection.
>>545481978>Elon the ashkeNaziWhen is the world's first trillionaire going to arm the people of his fatherland to stand against the Bantu invaders?
>>545481305It is super cold in space. But because there's no air, there's no matter to transfer heat via convection or conduction, so it's way slower for anything warm to lose its heat via radiation.
>>545480953When the spinning ball-Earth is finally exposed worldwide for the 400+ year deception it was, Earth's entire population will suddenly be faced with the reality that every government, every space agency, university, secret society, religious organization, mainstream and alternative media outlet have ALL been duplicitous in propping up a monstrous manipulation to fleece and control the masses. The resulting mass mental exodus away from the control system is exactly what humanity needs. Once the flat Earth truth gets out, these lying politicians, spokesmen, reporters and teachers suddenly change from being heralded voices of authority to being ridiculed, shunned and denounced as they deserve. Once the flat Earth truth gets out, these governments, universities, media outlets and other entangled organizations which have long been hard at work weaving this multi-generational ball-Earth myth, suddenly and completely lose all credibility. Once the truth of our flat Earth gets out, so does the truth of these few elite families/societies who have kept this most important and fundamental reality from us for these hundreds of years! Essentially, once the flat Earth truth gets out, so does every other important truth by proxy, because this "mother-of-all-conspiracies" holds under its umbrella literally ALL of the other conspiracies, and exposes them.

>>545480953>man who wants to mass import 2 billion child raping, sister fucking, civilization destroying Indian Hindu rape rats into white countries is a fucking retardIn other news, water is wet.
>>545482650The hardware is generating a limited amount of internal heat via the solar panels, though. It's not that hard to calculate how large of a radiator you need to handle the cooling.We have a whole ass space station up there and the radiators work just fine.
>>545482350If you did specifically want to have cooling done by space itself you'd basically need to figure out how much cooling is required for everything in your system, then find out how long it would take to cool the medium (air, water) via heat radiation in space, and then have enough excess able to be cooling in the background to always have fully cooled medium ready. The main issue with using space to cool stuff is just that it's slow because there's no convective or conductive heat tranfer.
>>545483053Yeah, you're 100% correct.
Conduction obviously isn't a cooling medium that applies in space, but you can radiate an infinite amount. You can radiate as much as you have radiators for, which isn't the case on Earth, because as you radiate you're heating your local atmosphere.
>>545482676>"You can tell it's real because it looks so fake" -Elon Musk
>>545482520Elon seems to take great glee in doing things that people specifically told him were impossible.It is a great motivator. I do agree.
>>545480953Did he mean shade? Or no shade? If shade it super cold and is vacuum but also not super high conductivity better is vacuum chamber with very little gas maybe consider bringing poncho like tent and allow fuel leakage then release the gas this cool even faster
>>545481230i never understood why the word retard suddenly became a banned word like faggot or nigger
>>545483221Also, the hotter the radiators, the more they radiate.So - heat pump.
>>545482439that's one small cultural victory that capitalists got>I paid for something, therefore I made it
>>545482520To use the same method that they use for satelites you would need a radiator that is hundreds of thousands of square meters for a 50-100mw datacenter. That's not feasible.

>>545481230like all offense it is taken by someone else on their behalf
>>545481439>man on mars by 2016I cannot wait that long
>>545482106AI answered this just fine
>>545483736hes such a dork he tried to invite himself to epsteins island and got rejected multiple times
>>545481190With radiators, same as how all satellites are cooled
>>545480953Space isn't a vacuum it's a thin plasma
>>545483572You scale the radiator up in direct proportion to the solar panels, through which energy enters the satellite The radiator will always be smaller than the solar panels
>>545484030Even the chomos think he's too offputting for their taste.
>>545483572You should look more into how radiative cooling works so you don't look like a retard like the shitter poster in OP. Energy transfer via radiation isn't linear with respect to temperature differential, it's a power function. Using a heat pump for example to increase the absolute temperature of the medium in the radiator increases the rate of heat transfer dramatically. You don't even need very sophisticated methods to reduce the necessary surface area of the radiator by an order of magnitude.
>>545481305> vacuum is coldAmerican education everyone
>>545484105>let's spend billions to pollute low earth orbit with a giant piece of shit hundreds of kilometers widefully retarded. but to be expected from a subhuman who legitimately wants to dyson sphere the sun and block all light from reaching the earth at all
>>545484259Radiative heat transfer isn’t linear thobeit
>>545483376>Did he mean shade? Or no shade?Shade The data centre satellites will be in sun-synchronous orbit, which means they always hold a fixed attitude to the sun, orbiting over the day-night divider, and precessing gradually to adjust over the course of the year.This means the sun is always in a fixed direction, the faint heat from the Earth is in another fixed direction, and the endless void of space is in a direction 90° to both. You point your radiators into space, edge on to the sun, and they will be facing constantly into an extremely cold heat and sinkIt's actually an easier situation than a regular satellite which has to contend with the Sun moving all over the place
>>545480953>Get's hit by space junkWhoopsie!We just lost all human knowledge pertaining to the 13th Century!
>>545484422It's not going to be one giant data station in orbit, it's going to be a large constellation of smaller satellites that network together.
Elon Musk is an actual, medically diagnosable retard and serves as living proof that luck is a quantifiable stat.He has fucked up everything he's ever touched to such a ridiculous degree that he got ousted from every company he's ever been part of for tanking said company before he bought Tesla. The luck part comes in the form of him getting a golden parachute from every one of these companies for seemingly no reason (the reason is because he's a member of the tribe.)Eventually he got rich enough that he could just pay people to translate his bullshit from retard into something workable.
>>545484687That's the case with respect to heat of the radiator The efficiency of radiation increases with the fourth power of radiator temperature. So the hotter the radiator, the better.But for a given radiator operating temperature, the amount of heat it has to dump is linearly proportional to the area of the solar panels, through which heat enters the satellite.That's what I mean about scaling up a given design linearly
>>545481190this is a solved problem, as evidenced by the fact that we have satellites and space stations in continuous operation in space. what is also a solved problem is how much surface area is required per unit of heat -- this is the part elon is clearly clueless about. for his grok ai satellites, the majority of mass lifted to space needs to be radiators.
>>545482490Jan's wrong because he is only thinking about traditional convectionThe void of space is an ideal environment for IR radiation
>>545484887it's all space junk that is vastly more expensive than the terrestrial centers that no one even wants to begin with. all just to secure more government contracts so musk can continue to larp as a billionaire instead of a fucking retard
>>545484983>what is also a solved problem is how much surface area is required per unit of heat -- this is the part elon is clearly clueless abouAlright, how much of a standard satellite do you think is radiator, compared to its solar panels?
>>545484105Satellites produce much less heat than PCs and still require sizable radiators. That should be something you intend to discuss upfront.
>>545484887Kessler syndrome gonna be a bitch, but that's a fun problem for future generations to solve with AI
>>545485151they're all in low orbit, Kessler syndrome isn't a problem

>>545485237completely delusional
>>545483676There is matter, its just extremely sparse (more inside solar systems, less in the true great void of intergalactic space). Temperature is a measure of movement of molecules in a given area. Little matter means not much movement which means cold
>>545485400they still encounter trace atmosphere in low orbit, drag will bring them down within a few years at most once they are out of propellant or otherwise unresponsive
>>545482650>there's no matter to transfer heat via convection or conductionwhat is stealing all the heat then ? the sun while radiating you in full power without the heart protection ?man the more i hear about space science the more it sound bullshit

>>545485130And how big do your solar panels have to be to generate 1MW? I’m not saying it’s technically infeasible, I’m saying it’s a stupid idea on multiple grounds to just not have them on earth. Y’know where it doesn’t cost tens of millions of dollars/kg just to hoist shit

>>545481305It's not "super cold in space". It's a fucking vacuum. What could possibly be cold?
>>545485130satellite mass budget per kW_IT: 13.3 kg/kW (optimistic, 2026) to 68.1 kg/kW (conservative, 2040) of total satellite mass, with a central 2026 figure of 33.3 kg/kW. for radiators specifically, the median estimate is 13.6 kg/kW with a range of 4.1 to 22 kg/kW depending on panel areal density and operating temperature. when scaled to 120 kW, roughly 0.5 to 2.6 tonnes of radiator per satellite, with about 1.6 t central
>>545485237>they're all in low orbit, Kessler syndrome isn't a problemI'm curious, could you describe Kessler syndrome to me
>>545486109You’re right, I just pulled a number out of my ass. Point stands though, it’s silly to not just have them on earth. Basic engineering principle: keep it simple, stupid
>>545485506Why when sleep on ground me get cold faster than when me sleep on bed?Space is cold because there's (almost) nothing generating heat, but at the same time there's nothing taking it either.Your body produces its own heat, without anything to move it off you you'll overheat and start dying.It's why whenever there's a heatwave in your shithole of a country people start croaking, one day with high humidity and suddenly their sweat isn't being removed from their skin causing hyperthermia.
>>545481190this is what the west's future looks like: a bunch of smug brown redditors saying the most retard shit that's even imaginable
>>545482066It's all nonsense. Everyone knows the soul recyclers are under the firmament.
>>545485641Kessler syndrome can only occur in middle orbits. In low orbit the shit will decay in a few years, in high orbit there's so much space that it doesn't matter. Kessler syndrome is a meme anyway. It would only mean a somewhat higher attrition rate for satellites. It wouldn't make space off limits

>>545485400LEO orbits decay naturally rather quickly.its nearly impossible to ADD velocity/energy to an collision that is greater than any of the two colliding objects. - so orbits won't get (significantly) higher. Most of the time the collision significantly reduces the total energy, due to heat being released.Orbits could get more elliptical, which would make their apogee higher and start to cross into higher orbits - but it would almost immediately correct itself because the perigee would be significantly further into the atmosphere.So its basically a non-issue since even if it were to happen, it would "clean itself up" in like half a year.

>>545485400If you're concerned about shit orbiting at LEO at 300 miles up I don't believe you have even a highschool physics student's understanding of orbital mechanics.>>545485641You do know that the service life of starlink satellites at their designated orbit is limited by the ion thruster fuel they carry and use regularly to reboost their orbit right? They're skimming wisps of atmosphere all the time even when solar activity is low and will reenter in a year or two without those reboosts. Months or even weeks if solar activity is going wild and the upper bound of the atmosphere grows to envelop their orbit. If you want to get up someone's ass for threatening kessler syndrome go take it up with china and their constellation that they're setting up at more than double the altitude of starlink. The lower end of LEO is chosen for these things deliberately because even in the worst case scenario the orbital shell will self clear in a couple years. It's mid-high LEO up to GEO where the real risk is because nothing that we know of is going to take care of shit that high up there. Well almost nothing, pic related.
>>545482066>insulation means immunity from heat transfer.

>>545487146I'm happy for you, anon.>>545487388>(almost) nothing>wat aboht san tho?Gee fucking willikers, are YOU retarded? Why is the dark side of the moon so cold? Shouldn't it be warming up the general vicinity like a commercial space heater...?
>>545481764Because light from the sun creates friction in the atmosphere and the heat from that friction is what warms the earth. Space is a vaccum so the light doesnt have anything to react with.
>>545487841you are a fucking retard jesus christ, these arent the radiators in your apartment Jamal, these are radiative heat rejectors.
>>545487478>Radiation propagates through a medium of matter,this is an incorrect statement. electromagnetic radiation is self-propogating, meaning it needs no medium
>>545487700A single NVL72 rack pulls over 130kw continuous load these days anon.
>>545487884Woah hey buddy easy. You're not supposed to be talking about what you can do with those phased arrays every starlink satellite is currently ostensibly using only for data transfer or why musk suddenly became so outspoken about the weakness of modern stealth plane technology. I'm sure all those things are unrelated to eachother as well as these orbital datacenters as they call them.
>>545487266>they are probably less efficient out of the atmosphereOn the contrary, they are more effective without the atmosphere because there is more sunlight shining directly on them
>>545488279qrd?
>>545487651Yep, which is ludicrous>>545487841You are aware these things can melt, right? Theres a hard limit on the temperature you can sustain in your flying datacenter\radiator.
>>545488369https://youtu.be/qn0uYtCScsw&t=41
>>545487327this
>>545488393Yes, and the radiative energy released per square meter per unit of time depends on the temperature of them.
>>545488393>these are radiative heat rejectors.Which reject heat in proportion to the 4th power of their operating temperature
>>545486541>His posts always comes offt.jeet indian ESL the post
>>545488200>You're right that the vacuum itself has no temperatureMatter cannot exist in a vacuum - it would demolecucuralise instantaneously.Think about it like the difference between the 6th Dimension and the 7th dimension You know what happens there right?
>>545488363>Why is the dark side of the moon so cold?Because it's OUT OF THE SUN, retard.A satellite is directly in the Sun for most of the time
niggers dont know how infrared radiation works. low solar absorption, high IR emission
>>545488369Why is Mercury hot
>>545488535>On the contrary, they are more effective without the atmosphere because there is more sunlight shining directly on themWell yeah, that TOTAL energy going into them is higher, and the energy they put out is higher, but their efficiency is still lower since it's still a ratio.
>>545488234>... at what temperature?Uhmmm.That's 100MW of dissipation, instantaneously.That's thermal equilibrium.If you have 100MW worth of Compute in operation, it requires 100MW of Cooling within the same instant, otherwise, the equipment warms and the Pressurized vessel warms.
>>545483676It's not "cold" in the way you're thinking. It's that you're radiating your body heat as electromagnetic waves out from your body, and nothing is replacing that heat.
>>545488810... hence why their radiators are kept in the shade behind the satelite.
>>545484377Checked and exactly right. I swear midwits will kill us all.
>>545488275And thats just the radiator part. Fixings, workers, the literal datacenter itself. All extra.This isnt feasible with current capabilities and its because cooling is a pain in the ass in space.
>>545489118What's the difference between the 6th dimension of the 7th dimension ?
>>545488780thats retarded, and not true. if its a true vacuum, there's inherently no matter - its not true at all that matter cannot exist in a vacuum. it only works one way. are you a nigger? what do you think happens if you put a chunk of lead in a true vacuum, it disintegrates? tard
>>545484983>the majority of mass lifted to space needs to be radiators.Unfolding radiators have been under development for a while. The surface area is more important than mass so they can dissipate an order magnitude more heat per kg.
>>545488948>That's 100MW of dissipation, instantaneously.>, you need roughly 500,000 square meters of radiator surface area—Ok, at what temperature? The dissipation of a radiator depends on it's temperature. Make it hotter, and it dissipates a LOT more energy. Make it colder, and it doesn't dissipate very much.Your "roughly 500,000 square meters" is at what temperature? Or did you just pull that bullshit out of your ass?
>>545488200>but objects within the vacuum equalise at the same temperature of 3K, unless heated up by the sunYes, but due to the T^4 proportionality of radiation heat transfer rate to temperature, they approach that 3K very very very slowly at reasonable temperatures for electronics.
>>545489339yes, all the calculates I've posted are 2026-2040 designs. the math doesn't work based on current tech
>>545488810Whenever I feel bad about our education system there's always some inbred yurotard on here who reminds me that even if we improve it people will still choose to be ignorant and argumentative.
>>545489348For example, the ISS radiators run at between 3*c and -40*c, (incoming "hot" coolant and outgoing "cold" coolant) and still radiate up to 84kw.
>>545480953Elon, like many retards, has learnt his space physics off movies which are also written by retards. He's seen a scene in a movie where someone's space helmet falls off and they flash freeze and he thinks that's real life.
>>545489348These people are fucking retards, no one in this thread knows what the Stefan-Boltzmann law is. They don't understand how it works intuitively and the fact that they're talking about 100MW installations shows how wrong they have the entire problem domain modeled in their heads. Don't bother explaining it, pearls before swine.
>>545480953Why should I listen to a retard that thinks space is a vacuum?
>Teslas are great carsxD xD xD xD xD xD xD
>>545481230There's many types of retards, retard. Only one type of retard is the handicap one.
>>545489001What a retarded idea, the dark side of the satellite is not as shielded as the dark side of the Moon. It would have to dump the heat as soon as it gets it and the heat has to pass through the satellite so it would cook everything in the wayYou're stupid and you make shit up.
>>545489909>What a retarded idea, the dark side of the satellite is not as shielded as the dark side of the Moon.Why would it not be?
>>545489612>No argumentsThat's what I thought.
>vacuum is an insulator>radiation flows without impediment>evaporative cooling can cool to near absolute zeroOh no, sparse solar wind is a poor conductor of heat?
>>545489348>at what temperatureThe Temperature doesn't matter.Only the Heat Exchange does.You are Transferring (dissipating) 100 Megajoules of heat FROM the pressurized spacecraft to the Panel array, and radiating 100 Megajoules of heat into Space.As long as the ratio is 1 to 1, then the Compute equipment's temperature doesn't rise a bit, nor does the spacecraft's ambient air.
>>545489762
>>545490191>As long as the ratio is 1 to 1, then the Compute equipment's temperature doesn't rise a bit, nor does the spacecraft's ambient air.Your compute equipment can be a different temperature than your radiators. Heat pumps, exist.
>>545489263It demolecularises yes because a Vacuum CANNOT BY DEFINITION contain matter.Do you even know the difference between the 6th and 7th dimension?
>>545490010Because the Moon is several thousand miles thick
loling at the retards in this thread
>>545490415How does that change anything? Is the satellite somehow slightly transparent and sunlight is getting through it?
>>545489792its like a mobile gas van in nazi germany except the victims buy it themselves and it looks like an accident
>>545489348The GPUs burn out at ~100C.Data enters themselves by code have an automated failsafe at 45C.So there you go. Not hot. You need geographic scale radiators to not melt your GW class datacenter to slag, and launching all this is simply not feasible taking centuries to millennia with current capabilities all devoted to it.
>>545489764>Stefan-Boltzmann lawSounds Jewish so probably BS
>>545481230>Retards themselves don't get offendedCan confirm. Am retarded."Retard" means "victory".
>>545490638So your calculations were at 100*c? 45*c?Also, heat pumps exist. Your GPUs can be a different temperature than your radiators.
>>545489629>For example, the ISS radiators run at between 3*c and -40*cYeah, I get your point.The Working Fluid and its capacity and operating temps.It's not really important for the sake of this discussion.The Working Fluids do exist.It's only a matter of optimizing Quantity and Flow rates.
>>545490638Why don't you just solve the back reaction problem and then you wont need coolants because you extract the energy from the aether
>>545490519transparent aluminum is real, so yes.
>>545490519It changes everything because the side of the Moon in the Sun gets absolutely cooked inches deep, so thin things gets cooked all the way.
>>545487590You don't need 100MW though. You can serve dozens to hundreds or even thousands of customers on a single Blackwell superPOD unit. Inference becomes extremely efficient at scale thanks to batching, as long as you have enough memory for the KV cache, which has also become extremely efficient. Just look at chinkshit models like Deepseek v4.1 Flash. A full 1 million token context only uses like 12GB or something. And Deepseek is way behind Anthropic and OpenAI. Besides rumors we don't even actually know what kind of shit they're on, except the fact that even now Opus and Astra are kicking everyone's ass up and down, and those aren't even their best models.A single scalable superPOD only uses around 1.2MW + 0.1-2MW for any additional equipment, like cooling, and power efficiency losses. Let's say you throw up 2 or 3 units. You could be serving 10,000 users Fable off one satellite at more or less the same time. Probably more. Or you could be serving 100,000 or more free users who only get 8k tokens and some really small shitty models. Probably over a million, if we're being serious. Anthropic claims that serving inference is extremely profitable and their losses are mostly from capex commitments and on demand leasing. Pretty sure their inference efficiency is actually beyond that of the chinese models that everyone likes to fellate. There's no way a jew like Dario would ever take a long term loss on it, and if the profit isn't coming from their business model, and it's not because the subscription plans are extremely generous, it's coming from the tech.

>>545491623You can weasel around all you want but you fucked up and you know it.A tiny satellite doesn't have a sufficient "dark side" to hide it from cooking
>>545490638The radiators contain heat pumps and working fluid
>>54549181460% what?
>>545480953You are fully retarded Democuck.Radiation is loss of temperature in space, insulation doesn't stop radiation, it stops convection and conduction. Retard Democuck Flaggot. There is a reason why Elon is rich and you will never be a woman who can get attract rich.
>>545491852Parsons the Thelemite ?One is retarded and the other is insane, tough choice so I'm gonna go with "neither"
>>545484983You need a lot more radiators than that for the size of those solar panels.
>>545480953I think I am starting to understand the reasons why stupid people are against AI. It tries to correct them of their misconception, and they sit there and argue with it.
>>545491327It takes approximately 2200 square meters of solar panels (at 35% efficiency, out of the atmosphere) to generate 1mw. Under 50x50 meters.So ~100,000 square meters to generate 50mw. less than 320m by 320m.Honestly not all that big.
>>545492071Of American population, duh
>>545480953He's right and wrong. Larger objects have a harder time cooling down because (presumably their TDP) as their volume is increasing x^3 the surface area is growing far slower by some coefficient to the x^2. The radiative effect of cooling will be less and less compared to the power used as station size increases.If you have a massive field of heatsinks radiating your heat into space it's technically a very stable and long-term solution with no moving parts.
>>545490051>No argumentsYou made none, and in turn received none.Maybe try actually reading a post and googling it, I'm sure grok/chatgpt can explain these things if you ask for them to treat you like a child.
>>545492023If all you're worried about is conduction, then just put like 6 inches of aerogel between your "shaded part" and your "hot side".
>>545492236And then you need another 800-1300 square meters of radiators per MW.
>>545491585nerve gas?
>>545492603True, but that's significantly less radiator-per-mw than solar panel-per-mw. Hence the "its easier to get rid of heat than to collect energy".Also 800-1300 sqm at what temperature?
>>545491184You have no idea what you’re talking about
>>545487995>isn't technically coldIt's not technically, it's literally not cold because there's no matter in space to be cold. Magic school bus was wrong about you freezing instantly when in space.
>>545492236>>545491327
>>545492236>Honestly not all that big.Oops you forgot the Cooling arrays.There's also zero tolerance for failure.With zero active cooling and negligible radiation to the outside (since the vessel is acting like an insulated thermos bottle), 100% of that energy goes directly into raising the temperature of everything inside.POOF
>>545487607Your mom's mouth.
>>545491651It's plainly obvious they're throwing the best they have out to the public as soon as they can, just from the fact that all the Anthropic and Astra output leaks came from China. They're getting access to the enterprise programs, probably through the gooks, who've been caught multiple times selling proxy access to China on the side, and they readily used models like Fable and Astra before they were available to the general public even though China is specifically embargoed from accessing the models. All those big state-backed corporations are paying big bucks to access American leading models a few weeks early, for obvious reasons.
>>545493065Good post, thanks
>>545490769>>545492044Lets throw even MORE energy at the problem. Which due to the second law of thermodynamics mean we will need even more energy and radiators to deal with it on and on and on.
>>545492603Not exactly. Space provides an extremely cold environment to radiate heat into, which makes cooling much more effective. At an industrial scale, some of that waste heat could even be recycled to generate additional electricity. This does not create more energy than it uses, but it can be highly efficient. The significant cooling advantages are one reason why the idea of placing large server farms in orbit is considered viable.

>>545494100Combustion and thermal kinetics Aren't we a little old for that
>>545491579>Sure, but you just increased the complexity and maintenance enormously.Inference is a competitive field. Besides the fact you have third parties in the business, like Cerebras (who's struggling a little lately), there's going to be a lot more first party hardware. Google already does it with their TPUs. Anthropic and OpenAI are also both reportedly developing their own chips. And Tesla technically has been for some time, with their Tesla hardware. In a couple years from now the main cost of inference is going to be RAM, but you have CXMT getting into the business, and SK Hynix, Micron, and Samsung aiming to double, maybe triple, their output in the next 4-5 years and even more beyond that. And if Musk actually does get Terafab up and running it'll be even more. So prices will go down. And when that happens the compute will become extraordinarily cheap, you'll see the bubble, or at least part of it, "pop" and the winners will consolidate hardware for pennies on the dollar compared to today. It's absolutely realistic to plan for a near future where the hardware becomes extremely cheap. Not to mention models are becoming more and more efficient. So will the complexity and maintenance matter when it's trivial to just shoot another AI rack up into space? That's basically how starlink does business now.

That's basically how starlink does business now.Nobody knows yet.Nobody knows what the costs will be either.The Unit cost must be so low that it permits for high failure rates + rapid replacement; as there certainly won't be an "onsite repair" unless there's an R2D2 about to be unveiled tooThen you have the issue of disposal.Undersea datacenters make the most sense, for cooling and even wave power generation.
I think the point being made is that in space, there is no atmosphere. So the air doesn't communicate heat away from an object. So the only way an object can lose heat is through thermal radiation. Therefore objects lose heat slower in space.But in space, you have....well....space. So you can straight up build football field size radiators if you wanted.

>>545487126>cosmic microwave background radiation which is everywhereBecause they told you so or have you measured everywhere?
>>545493510You are absolutely 100% wrong. There is no temperature in space. Only matter can have a temperature and only matter can transfer heat. A single high-end GPU (~700 W) needs on the order of 1–2 m2 of radiator surface to stay at workable temperatures. Scale that to a full rack or a megawatt facility and the radiators become enormous and heavy. The ISS rejects only ~70 kW with hundreds of square meters of radiators; going orders of magnitude higher multiplies mass, launch cost, and complexity. Day/night thermal cycling, radiation degradation of coatings, and the need to point radiators away from the Sun and Earth add further constraints.
>>545494155>>545485147>>545484422>>545487029These Anons and probably more don't understand emissivity of objects in space. Thought experiment - where is planet earth's radiator? or the moon's for that matter.
>>545480953Jan is right, while space might be cold because there is no air to be warmed, that is exactly why it’s harder to cool down things in space - the heat of an object gets stuck in the object because no air to transfer it away. The heat only gets transferred out of that system by thermal radiation which is very slow and inefficient. For example, astronauts working in space generate body heat that cannot escape into the air, which means their spacesuits require specialized water-cooled garments to prevent them from overheating
>>545495881Too many dipshits in this thread don't understand that radiation is a fucking piss poor conductor of heat. All they need is a vacuum flask filled with hot water to see how effective of an insulator a vacuum is. The morons think because the Sun can warm objects in space that space is an effective way to transmit heat. The shitheads fail to realize that it is MILLIONS of degrees in temperature yet the plants JUST warm enough to support life. If space was as effective a conductor as air, Earth would be fried. But they're too busy sucking Elon Musk dick to learn a damn thing about thermodynamics
>>545496846isn't that the guy who cucked/sanitized maxwell's equations for the globalists? length contraction, rofl.
>>545481190>>545481230Elon is right, and the professor is retarded. Space is the only and final heat sink into which all heat on Earth is directed. Every watt consumed by every data center, ultimately radiates as heat into space. The balance between energy from the sun and energy radiated into space is what sets the temperature on the Earth's surface.So data center satellites simply remove the intermediate steps.
>>545488279Um... What fluid are you moving in a near total vacuum though?
>>545494100they absolutely are not.this isn't even difficult math to figure out.take the size of the data center you want to build, divide by the efficiency of the solar panels to get the total thermal energy you need to disipate from the system, and divide by the emisivity of the radiators to get the square meters of radiator panel you need.I just fed this into Gemini and, I'll spare you the full output (you can do it easily yourself in 30 seconds), the most generous estimate says that for a 1GW compute data center you need 2 square kilometers of radiators, the more realistic estimate is 5

>>545495881>There is no cold matter to take away heat. There would be next to zero heat transfer.infrared radiation. face the sun and it heats shit up (that's why the earth is hot, dumbdumb). face darkness and the heat radiates away as infrared light.
Suck" is not a fundamental pulling force in physics; rather, what we call suction is entirely driven by a pressure-gradient force where higher pressure pushes toward lower pressure.From a scientific standpoint, everyday objects and fluids are never pulled by a vacuum; they are always pushed by the higher-pressure side. Users on Reddit broadly agree that the term "suction" is simply a colloquial label for this pressure differential rather than a standalone physical mechanism.Here is how common examples of "suction" actually work mechanically:• Drinking straws: When you use a straw, you expand your mouth to create a low-pressure zone. The higher atmospheric pressure acting on the surface of the beverage then pushes the liquid up into your mouth. As explained in the educational video "Nothing Sucks in Physics", this reliance on atmospheric pressure means a vertical straw can never exceed a maximum theoretical height of roughly 33 feet (10.3 meters), because the weight of the water column eventually balances out the maximum push of the atmosphere.• Suction cups: Pressing a cup against a wall expels the trapped air, creating a localized low-pressure pocket. The surrounding atmospheric pressure pushes forcefully against the outside of the cup, holding it firmly in place.• Vacuum cleaners: An internal fan expels air from the unit to generate low internal pressure. The higher-pressure room air rushes inward to fill the gap, sweeping up dirt and debris along the way.• Breathing: When your chest cavity expands, your lungs experience a drop in internal pressure. The higher atmospheric pressure outside literally pushes the air into your airway.Ultimately, because a perfect vacuum represents a pressure of absolute zero, it cannot exert a negative pulling force. All movement in these scenarios comes from the positive kinetic energy of particles in the higher-pressure region pushing outward.
>>545498148Again, radiation sucks as a heat sink in a vacuum. What people think of as radiating heat on Earth is conduction via air molecules, aka convection. You'd know this if you got off your knees and popped Musky dick out of your yap

>>545498600But near complete vacumes are better at keeping things cold then keeping them hot?
