>>108441077>>108441043
>>108441154without air to carry away heat via conduction/convection cooling in space happens entirely by radiation. cooling anything is actually the challenge, not staying warm. The ISS for instance has huge radiators to help it not overheat and it's using a tiny fraction of what an actual data center would use in space. data centers in space make absolutely zero sense

>>108449194- Easy to cool down.- Satellite solar panels are self cooling, back sides of solar panels in polar orbit will have far better cooling power than for equatorial orbit because they aren't facing Earth.- Wind and hail resistance aren't free either. PV in space can be a couple 100 Micron thick, PV on earth 35 mm.- There is no maintenance, if a section malfunctions you blow pyrofuses and route around it.
>>108452193>another retard who doesn't understand how energy transfer works, that you need a medium to transport energy, and that there is no medium in spaceStopped reading after the first line, commit seppuku.
>>108447001Its privately owned
>>108452213Blackbody radiation to deep space is nearly a kW per m2 at 80C.
>>108440999That is not how that works. Anything shot up is still under the jurisdiction of the company that shot it up there so unless they plan on using North Korea as a launch base which might be a bit difficult considering the sanctions this changes nothing about jurisdiction or laws.
>>108452267Country not company but same difference in the end.
>>108448680not quite caused by but related to them deserving everything they brought upon themselves
>>108452248>radiation
>>108452248>nearly 1kw per m2 at 80c>meanwhile the average chip is 1 or 2cm^2 (and those are the big ones, they tend to be much smaller), ie 1/10k the area whilst consuming 100 to 600w.meaning, in the best case scenario, you still have 1000x less heat dissipation than necessary.thus proving that you are an absolute retard.>solar panels are self coolingwe weren't talking about cooling for panels, just the cost of energy, it cost so much to send a panel to space that you are not gonna beat ground electric price.>Wind and hail resistance aren't free eitheron the ground we can use hydro and nuclear.>There is no maintenance>dude has never seen any real world datacenter where parts need to be changed on the daily.
>>108440906>>108441043It's kind of retarded.Space is actually a pretty bad environment for cooling because heat needs a medium to transfer effectively. The only way something can cool down in space is by emitting energy as radiation (usually infrared).
>>108452306Yes, electromagnetic radiation. Mostly in infrared at the relevant temperatures.Deep space meanwhile sends about 0W/m2 back. So pretending Earth isn't there for a moment, all the blackbody radiation is cooling power.
>>108452335That's why you use refrigerant to spread the heat around. Like a giant heatpipe, except with active pumping.
>>108442664>>108443845>>108442957>>108443937>not instantly recognizing the artist by the extremely recognizable art styleActual plebs
>>108452335>>108452248oh and don't go "muh heatsink"having a 1m by 1m heatsink for each cpu is pure retardation when datacenters typicaly have hundreds of thousands of them.
>>108452383By sheer coincidence, you already need around the same area for PV to power them.PV on the front, radiator with refrigerant channels on the back. Problem solved.
>>108452382cmon anon, someone's already done the "heh you didn't recognize the artist you such a pleb"just tell us
>>108452401>uses tons of materials in a place it's expensive to get material to.brilliant.can you name a single advantage of putting datacenters in space if you don't build them there from space mining?sounds like you are just obssesed by a gay ass sci fi idea that has no real world practicality.
>>108452422>>108452401also you need even more materials for shielding because of background radiation.
>>108442944your move faggot
>>108452422>bro played either too much or too little spage
>>108452267That may be technically accurate, but that's not the point. The point is, if the datacenter is in orbit, it isn't easy for the government to raid it and obtain incriminating evidence against you. And if they do decide to burn taxpayer money and raid it in orbit, you'll probably have enough advance warning that you could just "accidentally" deorbit the whole thing before they get there.
>>108440906I look like this
>>108452422The amount of materials necessary in orbit can be far less than on earth. Lets say the PV and radiator are flexible Before you pump in the refrigerant the PV+radiator might only be say 200 microns thick ... it's nothing.https://www.researchgate.net/publication/331928106_GoSolAr_-_A_Gossamer_Solar_Array_Concept_for_High_Power_Spacecraft_Applications_using_flexible_PhotovoltaicsThe GPU/RAM/SSD/PSU cooling block will double as shielding and will have some weight to it, but nothing compared to rack mount shit. Even with increased density of modern racks, a fuckton of the weight is simply the racks themselves and the cases, which you don't really need in space.
>>108452517that's why i said it only makes sense if you do space mining and build in space.don't know about that game though.>>108452544>the amount of materials necessary in orbit can be far less than on earth>completly ignored the shielding issue.and no, it's still way too expensive to send mass to space for it to ever make any sense.>the PV+radiator might only be say 200 microns thick ... it's nothing.that's still besides the point you'd need some serious shielding.and all that for an unreliable mess that can't be maintained and more space garbage.>but nothing compared to rack mount shitthose don't need to be sent to space anon.>a fuckton of the weight is simply the racks themselves and the casesand?a fuckton of the weight is the cpu, the cooling solution and the electronics and printed circuit boards.and again : can you name a single advantage of putting datacenters in space if you don't build them there from space mining?the whole idea of sending datacenters to space when you can just have them on the ground is utterly retarded.and even assuming you could send them to space for cheap, the amount of engineering required to make it lighter etc would still make it not worth it.i think you underhestimate how much chips there is in a datacenter and how much it'd cost to send those to space, for literaly no benefit whatsoever.
>>108440906You can scale faster and larger without worrying about energy, because you have infinite energy 100% of the time with solar panels. You also don't have to deal with negotiating to buy lands and fight locals.
>>108440906When the poors start rioting and burning down data centers they can't get the ones in orbit
>>108452745>You can scale faster and largerThe elusive micrometeorite swarm:
>>108452765> The elusive micrometeorite swarm:Don't worry bro, leave it to me.
>>108452731The advantages :- Easily available continuous power, which doesn't take 10 years to build like a nuclear power plant.- Easy cooling without consuming water (not that cooling towers use a lot of water, but it's bad PR).- Free near infinite real estate to put them in.
>>108442944>exactly what it says it doesKek if that was true we would be flying from new york to tokio in an hour on a Starship.The only things space x has ever achieved are the falcon heavies and starlink satellites. Every other thing musk has said they would do was pure bullshit
>>108452821>Easily available continuous powermogged by nuclear and your panels being too costly to replace and also creamed on by space debris.>Easy cooling without consuming waterlmao, you'd cool 10x more effectively by doing the exact same thing on earth, ie passive cooling doesn't magicaly work better in space, quite the opposite in fact.>Free near infinite real estate to put them in.anon, rocket fuel isn't free and infinite.this only ever make sense if you build them in space from space mining.thinking it makes any sense to ship datacenter from earth to space is pure retardation.
>>108452821>Easily available continuous power>not understanding basic geometrywhat do you think happens to the power when the earth is inbetween your panel and the sun ?now you also have to ship a battery, more weight even more unrealistic a scenario.RETARD.
>>108452755with what? if they carry wood and bang it to the door they eventually might make to next door
>>108442924> ten times more difficultit's ten thousands actualy.
>>108441140>Practically free energy from sun, >effortless negation of heat/sound dissipation measures due to cold vacuum of spaceYou're so close, yet you haven't figured it out yet in your muskrat stupor.
>>108453112In a polar orbit perpendicular to the direction of the sun the earth never gets in between (this is not a sun synchronous orbit). The orbit will stay perpendicular to the sun, all day, all year.
>>108453458i know about lagrange points.but now enjoy latency that makes those basicaly useless only real stable one would be L5 and you are basicaly talking about a 16 minute ping.also you now made it 10x more expensive to ship stuff.try harder.
>>108453458>>108453482also you can't keep that orbit all year round without spending a nontrivial amount of fuel to keep it perpandicular.
>>108453458>>108453498dude shifting an orbit 1° a day would consume an absurd amount of fuel, not only that it's one of the harder orbital maneuver.
>>108453458>>108453498>>108453539also following all those point, launching a polar orbit is also a SHIT TON more expensive as you are not using the earth's momentum.
>>108453498Ignoring drag for a moment, the precession does keep it perpendicular. The satellite is rotating around the sun too after all.You always have to offset drag regardless, it might be possible to do it by using part of the satellite surface as an adjustable solar sail in higher LEO orbits.
>>108453653It's called a "full SSO" orbit BTW.
>>108440906Of course!No niggers to burn them down or mudslimes to bomb them with drones!
>>108440906The Stefan-Boltzmann law for thermal radiation is as follows:P=εσAT4Where:P is power,ε is emissivity (0 to 1),σ is the Stefan-Boltzmann constant (5.670374419×10-8),A is area, andT is temperature.Let's solve for A.A=P/(εσT4)Now, let's take 10kW which is a reasonably baseline TDP for a full rack. Let's assume the radiators are at 40°C, which is very hot (the ISS radiators run well below 0). We'll also select an emissivity of 0.9, which is reasonable.A=10000/(0.9×5.67037×10-8×(273.15+40)4)=20.3768m2This is the radiator area needed to cool that system.Now we neglected two important factors: the sun and the earth. Both the sun and the earth radiate heat towards us as well, which will make cooling more difficult.All of this covers just cooling, power and maintenance are a whole other issue. So is radiation and connectivity.
>>108453922>Let's assume the radiators are at 40°C, which is very hotNo it isn't.>ISS radiators run well below 0I guess they want to run their freezer on it for some reason then.For semiconductor cooling, a 40C radiator in space is as sufficient as a 40C watercooling radiator in a terrestrial PC. Works fine, you can go hotter if you want.
>>108453922>Now we neglected two important factors: the sun and the earth. Both the sun and the earth radiate heat towards us as well, which will make cooling more difficult.Full SSO orbit helps a bit here. The back of the PV doesn't face the earth. If you combine the radiator with PV, earth is low on the horizon from the point of view of the radiator. What they can do then is have a mirror foil wall to shield out the earth.
>>108452755they can burn down the place that you use to keep supplying the constant maintenance needs of your orbital data factory
>>108454273On second thought, shield is not really needed. Earth will fill only a small part of the hemisphere and the temperature of Earth is low enough not to be relevant.

>>108455409>he gets imprisoned at the endBahahaha
>>108455409>implying people didn't link it due to incompetence
I still don't see how you can effectively solve the cooling problem and not send a massive amount of material into space.
>>108456557Here's an option :You make the radiator out of some low gas permeability multilayer metallized plastic film and in space you pump refrigerant through it, in channels so it doesn't puff up too much. Refrigerant will mostly be a gas. Radiator doesn't need to spread heat, refrigerant does that, just radiate it. To radiate it just needs to be black, not a heavy piece of metal.So the radiator weighs fuck all and because most of the refrigerant is gas, it weighs fuck all too. Takes no space before the gas is in either.Now of course it needs to be attached to something, luckily the solar panels are right there and just the right size (doesn't work in a normal orbit like ISS, but does work in a dawn/dusk orbit).>What if a micrometeorite punctures itSelf healing and compartmentalization.

>>108453653that's just not how it works, have you ever seen a gyroscope?the orbit stays the same from the earth's point of reference, meaning, at some point it'll be in shadows.> it might be possible to do it by using part of the satellite surface as an adjustable solar sailnow 10x more complex and not even possible either, it's already hard enough to do it with rocket engines, let alone fucking sails lmao.simply NOT gonna happen, you'd spend as much fuel rotating it for a year than you used to launch it (which would be a gigantic amount because of the datacenter's weight).
>>108457499seriously dude just stop, this has no practicality, it's just pure retardation, the only way space datacenters make sense is if you build them in space from space mining, that's it.

>>108460528Space is a great insulator because there are almost no molecules that could be used for transfer.
>>108440906It doesn't matter. The cost to send up an operable data center and keep it in orbit is probably trillions of dollars. The likelyhood of this actually happening are among the same sort of timeline as us putting up a dyson sphere.
