Rotating Habitats & Spin-Gravity Megastructures

Ғылым және технология

Rotating Habitats, like the O'Neill Cylnder or Stanford Torus, represent ways to mimic gravity in space to allow comfortable habitats for humanity and our terrestrial ecosystems.

    I was unable to find where to send comments ("Add a public comment..." keeps opening my gmail.") so I used this method. Here is my question to Issac: At 22:18 in Rotating Habitats he says "...and they're spinning at nearly half a percent of light speed...". Is it true that they're spinning at 93.14 miles per second? That sounds really, really fast!!! Jerry Searcy jerrysearcy98@gmail.com

    Which isn't too smart, the gentleman who does most of the cover art for this channel these days experiments with a lot of procedural models that will render basically infinite variations on a landscape and spew out a stream of images that are photo realistic of random terrain. So the computer doesn't have to be too smart to design the map layout or compile the equivalent of Google Earth for a Ringworld. :) Now maintaining all that might take some more brains unless we actually want to have folks drawling around the exterior repairing collision damage or running whatever monotous process is involved with covering over the slow erosion from a lack of tectonics.

The insecurities from such an intelligent man make me think he must have gone through a pretty rough time growing up, I could be wrong and I hope he didn’t but if you see this comment Arthur, I love your information, questions, suggestions, and I never really think of your speech impediment.

    The stated tensile strength of some of those materials (kevlar, zylon, nanotubes) is the strength of the individual fibers. However as fibers are woven into a bulk material the strength dramatically decreases. For example typical carbon fibers can be found with a tensile strength of 4.3 GPa, yet the strongest carbon fiber composite that I'm aware of is at less than 1.5 GPa. They would definitely work great as reinforcement to improve the strength to weight ratio of structural pieces, but they wouldn't comprise most of the structure.

    Edgerino a carbon fibre rope will still be pretty close to the strength of one fibre. It depends how you load the structure, if you are using it as a spoke you can get near to the full strength. Around 1.5GPa is normally a yield for a high fibre content composite. Safety factors are way to complex for KZread comments

    Have you ever thought about extra-terrestrial minimalism. Most frontiers are conquered by individuals. What is the minimum society size that can live extra-terrestrially and how would it live? Woud burrowing into an astroid without much modification make for a good shelter? How would you mainain oxygen water food? Perhapase a blowup house that you simply dig into the center and blow it up. What kind of material would you need to support the level of pressure needed. How would you keep the gravel from gravitating toward itself in the case of being slightly off center, aka boyancy?

    as he said, gravity is so low the gravels gravity wouldn't be able to overcome the friction with the outside walls, i mean these asteroids are already extremely irregularly shaped because they don't have the gravity to pull themselves into anny real compact shape, if you hollowed them out their gravity would become even less... as for the minimum population, i like to think that's irrelevant, if you buld one or more of the cheap launch systems mentioned on this channel previously, odds are it wouldn't be very long until you started looking into building the orbital ring megastructure, since its benefits would out-weigh the cost on even the short term, since it would be really cheap and probably quiet profitable to get in-space mining operations going, and once you've made it this far, building your 1st O-niel cylinder isnt realy that much of a challenge annymore. as for the materials, the prices of creating graphene are expected to come waaaaaay the f*** down, especially if you have cheaper power sources, like say fusion plants for instants.

    In a way yes, but at the same time a smaller moon in geosynch with us, which would be a pretty common occurrence, or very small moons right over the Roche limit, might be even more handy. Less material to work with but even a tiny moon like Phobos would be handy if closer.

    You videos are amazing! I really appreciate that you talk at length on each subject and don't try to dumb it down. That's what makes your channel the best of its kind. It's nice that you subtitle - more people should, in general, for the hard of hearing, and for those who aren't English First Language, etc. - but I have no trouble understanding your voice at all, even though I'm Australian. Actually, get this - I listen to your videos every night before bed, because your voice helps lull me to sleep (although I'm always so engaged by the content, I usually have to watch a second video before I can let myself drift. When I think about the cosmos, even my biggest problems feel smaller). I thought you just had a very special Southern US accent. I'm really into linguistics and languages, so I'm always excited by regional variations. The way you pronounce vowels, at times, is actually closer to being Australian than a standard NA accent, so it doesn't sound strange to me, but it's probably more unusual to your fellow Americans. You also occasionally mimic the intonation of certain British accents. Your speech is wonderfully unique, and just one of the many things that makes your channel special. I know it must be difficult, but there's no need to be self-conscious. :)

    Would be cool to have a movie where they live on one of these rings or tubes. The movie could be about some normal life or adventure, and they would not show where they are until the movie progresses. At some point the adventure would lead for example to outside of the habitat either through the floor or to the sky. Then the audience would realise that whoa, they weren't on a planet. There could be hints like the horizon was different, but not too revealing at first. If it was a tube, it could have an inner sky tube to hide the other side.

    Great video. These megastructure videos are really intriguing; I'm constantly wondering "If this is what we could (hypothetically) do now, what could we do if "x" were true?" I.e. artificial gravity, or having a decanter of endless water from D 'n D and growing massive bio-structures (a tree-house...but in spaaaace), etc. The thought of staring up at the stars from the exterior surface of some massive space donut, surrounded by trees and rivers and such, is incredibly cool.

    One cool thing about rotating habitats is you can literally fly by moving in the opposite direction of rotation, until you are still, relative to the rotating structure. You will then be weightless. Just move up enough to avoid being hit by structures, and wait until your intended destination comes to you. Then, all you have to do is start moving again, util your speed syncs with the rotating structure, and land. Very little fuel or energy would be needed to fly like that.

    "Babylon 5 was an O'Neill Cylinder. Also one of the best SF shows of the '90s." HELL yeah! High-five! Heck, there was even an episode where somebody fell while crossing the center...and because there was no/little gravity there, away from the spinning sides, they kinda _floated_ down. I love this stuff. :)

    just recently discovered your channel and at the moment I'm going through the megastructures collection. and even at this point E04, there's a lot of concepts and ideas that I was not aware of, literally jaw dropping 😊 regarding your Trek comment I think your right, who needs Planets lol, I can see the advantages if you have a civilisation like this with warp technology and it would be even greater if they had replication tech as well, even if it's a primitive form, basic materials and alloys only and the energy costs would be pretty much free ( mine the stars then use gigantic solar powered replication foundry's)

    A cylinder within a cylinder system w var grav levels and even adjustable spin / grav could be useful for again industrial, commercial and medical applications as well as recreational. A habitation unit w a larger ocean and heavier landscape (mountains and etc) could be of use and if turning counter ways deal w rotational stress of some aspects of the mechanical systems. Just thoughts.

    Tapering one for dif grav levels could be useful for certain industrial and commercial applications, making certain materials for industry, medical and etc would be easier w less gravity. Building living structures for the rest of the cylinder would be easier in a section w less gravity. Recovery from certain injuries would be easier in less gravity, 1/3rd for some then 2/3rds and then normal grav. This could be on a dedicated medical cylinder in orbit.

    My favourite that I know of is the Kalpana1 design, because unlike you I am a minimalist by nature, it only so happens I read lots of SF in my day. Kalpana design is great because it is the simplest and the smallest of the ones I've seen. Passive stabilization, passive cooling, passive lighting. 250 radius, 250 length. If I expect any to be built within my lifetime, it's one this simple. Therefore it's my favourite.

    The big problem with doing low gravity for marine life is that it changes the balance of dynamic vs. static lift. What this essentially does is buff sharks, which should quickly evolve to be basically dense tubes of muscle that don't float, but use hydrodynamic lift. Their high density means low cross-sectional area would give them higher top speeds.

    Fun fact: after 24/48 hours of nausea in space, the human vestibular system tends to shut down and the brain then relies more on the eyes and ears for spatial awareness. As a result, it's actually really hard to make an astronaut nauseous or dizzy. Given just a bit of time, most of us adapt very well. There are cool videos of astronauts on the ISS getting spun around too high Gs and when they come out of it, they recalibrate in 3-5 seconds with little or no feeling of sickness. KZread "do astronauts get dizzy in space?" It's a NASA demonstration video about what I just described :)

    Delightful video! There's a charming fictional option that doesn't quite fit any of your categories: Karl Schroeder's Virga is a huge balloon of breathable air with no gravity (and a fusion "sun" at the center). Inhabitants who can afford gravity get it by constructing rotating habitats of various sizes - since these do not need to be air-tight they can be made out of whatever the inhabitants can cobble together. Since in this setting the balloon was conquered by some not-present super-high-tech society that makes impossible technology more advanced than jet engines, it makes for some charmingly retro-tech habitats, and "space travel" between them that doesn't even require air-tight ships. But the mental image of a small community cobbling together a habitat out of balsa wood and propeller engines is just charming.

    Karl Schroeder is an interesting author generally. One of his themes is voluntary refusal of technology: communities in a larger society that, like the Amish or (some of) the Mennonites, are surrounded by far-future technology but who choose to build a society that does not use some of it. It makes for some interesting situations, and it also gives you a more approachable viewpoint through which to see some of the fancy technology.

    How does heat dissipation work with a zylinder rotating in vacuum in a stationary shell? The shell would reflect back quite a bit of the heat radiation, till it is hot enough itself to radiate out into space enough. My gut feeling says that the temperature of he shell will be halfway between the average radiative temperature of space and the temperature of the rotating zylinder. So you would limit the heat you can radiate away severely.

  • @isaacarthurSFIA

    @isaacarthurSFIA

    7 жыл бұрын

    You'd expect the outer shell to be decently cooler, and it would be the ultimate radiator, but you could use convective and conductive radiation to move heat from the inner spinning one to the outer shielded one. You could also have radiating fins on it, either made of a good thermal conductor or with pipes flowing up into them to move the heat.

    16:00 or you could even have cameras on the outer shell, relaying their images stitched together in a mozaic to be displayed on the central "sky" cylinder inside. Thus letting the population look up and see a "tv screen" of what is actually outside the habitat. I think many people would be fine with that, sure they'd know that what they see isnt the "real" sky, but just a tv image of whats outside, but still. With higher pixel size than the eye can discern at that distance (honestly wouldnt be too hard, since the sky cylinder would be so far above your heads), it'd look as lifelike as we consider a 4k television image to look.

    Great stuff! Gone through about a dozen of your vids so far. Never had any need for the closed captions. Keep it up, I REALLY enjoy digging into another vid every chance I get. I noticed at least some of them aren't monetized? No commercials? You need to get paid something for your time Issac.

    Thanks! To be honest the only reason any of the videos are monetized in any fashion is that KZread has a couple special features only available if you do, so I use that tiny pop up where the closed captions go anyway, so it can be easily dismissed before I start talking. It produces a trickle of revenue that I figure compensates KZread fairly enough for hosting my material. I do have a patreon account these days that's linked in the video descriptions, and that seems to work better anyway.
