O'Neill Colonies - An Animated Tour

O'Neill Colonies
This video was around eight months in the making. It is a composite of three renders (made using Blender 3D, Photoshop, and DaVinci Resolve) showing the interior of an O'Neill Cylinder, a concept popularized by Gerard K. O'Neill in the 1970s. The basic premise is two cylinders, tethered together in pairs, each one rotating in opposite directions. This gives the colony stability and enables the entire structure to be moved in space via a gyroscopic effect.
Everything is constructed, mostly in orbit, from materials mined on the Moon or on asteroids. Each habitat has a thick lining of Moon rock or similar, to protect occupants against small impacts, cosmic rays and solar radiation.
O'Neill imagined the cylinders to he half land and half glass, with external mirrors outside directing sunlight into the interior. This is a waste of surface real estate, and of course not particularly safe, because the glass cannot provide the protection of a solid hull. Instead, in my interpretation, the light source is a beam running along the central axis, powered by a future technology - perhaps fusion reactions. Weather and interior lighting are intelligently controlled, and night can be simulated by modulating the light source.
Each cylinder rotates at 0.31 revolutions per minute, or 3.2 minutes per revolution. Given the dimensions of the cylinders, this creates an artificial gravity of exactly one gee at the surface, decreasing to zero at the central axis. The upper rotating platforms provide a place for residents acclimated to different gravities, maybe people used to living on Mars, the Moon, or other places. The radial struts, in addition to providing support, contain elevators which people can use to access the axis for low-gravity recreation, as well as the rotating platforms.

I am 100% sure, if we become space faring we will live in these one day and they will become increasingly larger. People tell me it will be impossible for people to build things this size but I tell them who said anything about people building them, we build the machines that will build them.

With Open AI and Google being on the verge of creating advanced artificial general intelligence and potentially the singularity, Im sure in the next decade or two we will atleast have the blueprints to create large space megastructures like so as AI quickly discovers every possible advancement in material science and engineering within our laws of physics.

[@reptilionsarehere]

​@billybobmonroe3166 Call me a depressing person, but I don't think the future of spacefaring humanity will be anything like in the video. Especially if AI leads the way to ever more rapidly advancing technologies and discoveries. Whether you, me, or anybody else likes or approves of it or not, I think AI will try to shrink space craft and increase efficiency regardless of opinion. That means instead of something like a big and mostly hollow cylinder full of current comforts filling it... I personally see something more like humans being digitized, stuck on small probes filled with powerful hardware, and allowed to socialize in simulations while they travel star to star. Who knows, maybe we already are....

[@billybobmonroe3166]

@@reptilionsarehere I think your probably right, building something as large as an o'neil cylinder would be inefficient when compared to just stacking humans in a cargo bay and letting them live comfortably in virtual reality. In fact I think theres a significant chance humans don't venture far into space at all as we would begin to favor being omniscient gods in virtual worlds just as realistic as our own. My main point though is AI will begin to solve for every possibility in our given laws of physics. So if giant space mega structures are physically possible AI will figure out how it could be done whether they are every built or not.

I’d like to see a movie set on one of these. The whole plot of the movie would play out inside the station and the fact that it was taking place on a giant rotating space cylinder wouldn’t even matter. But you’d see it in the background. The actual story could be a love story, or a murder mystery, or a comedy, etc.

[@dilluminatilair]

[@bbartky]

Nice work, Mark! I really enjoyed this.👍 I also like your decision to have a solid hull and not use huge amounts of glass. Interestingly, this seems to be the direction that most recent space colony studies are going towards. Fraser Cain, who runs the great astronomy and space exploration website UniverseToday, also has a great channel here on KZbin. Recently, he interviewed a scientist whose proposal is to build a colony with a rubble-pile asteroid like Bennu. Basically, you would puta giant “bag” around it and the spin it to shape the rubble into a cylindrical shape. That cylindrical rubble pile would then be molded into the colony’s hull. A solid hull would also be much better at protecting the inhabitants from harmful cosmic radiation.

[@bloops9188]

At "only" 35 km long, 800 km/h vacuum trains don't really make sense. Modern transit technology would just do fine. Good work on the visuals though - the world needs more space habitat art! And even if a couple details don't make sense, it's good to have a futuristic sense of imagination. ^_^

[@max8286]

I agree, I would reduce flying objects because they´re not really necessary and a permanent danger for the outer structure. but very cool reproduction of ideas painted in magazines in the 70 and 80s

[@denvercolorado-olegmogilev576]

I have a retro-book, published at 1979, about O'Neil space colonies, buying somewhere online, it was a long time ago, and I'm not sure where I bought it!

[@StanleySchmengie]

I read numerous books back when O'Neill released his first book (The High Frontier; Human Colonies in Space, 1977 ) and became very interested in this subject. I honestly thought that by 2024 we would have at least built a toroid by now (Like in "2001, a Space Odyssey") and that I and many millions of others would be working and living in such a habitat. There are a lot of interesting phenomena that would be possible and required with these structures, as well any large rotating habitat. For instance, if you were to enter such a structure as pictured at the beginning of this video, getting "down" to the inner surface would likely cause nausea in most people, as the sideways acceleration coupled with the slowly increasing gravity effect would cause you to feel sick to your stomach. Therefore the elevators, if you will, would likely move fairly slowly, so that it might take an hour or more to move from the centerline to the livable surface. Another cool possibility discussed was how you could set up swimming pools in low gravity. You could build a curved floor pool and place it near the centerline so that the gravity was a fraction of the outer surface experienced, but still enough to keep the water in the pool and not have it form a sphere like we have seen in videos from the ISS. If the gravity was properly balanced, an accomplished swimmer could actually swim fast enough to get themselves out of the water! Human powered flight, with a pedal powered aircraft would be very easy if launched from near the centerline, and even from the surface if the gravity was less than "Earth Normal". You could easily control the climate in each of these cylinders as well. Have one that was perfectly temperate for the raising of crops. One that was always 72 degrees F and sunny! One that was cold and snowy for perpetual winter sports, etc. Humanity needs to do this. We need to move off this planet and let it heal. We have the technology (we've had it for over half a century) and we can develop those technologies we will need. Instead the human race as a whole spends several billions of dollars PER DAY on weapons, material and devices designed specifically to kill each other. We need to evolve so that humanity can thrive together, not continue to fight over scraps.

[@islandpalm148]

For species who like natural sun, the window areas are as important as the ground areas. The areas are protected from solar radiation by the fact that they never face the sun. The mirrors do. Some of us like to "catch rays". A central light tube won't do the trick. O'Neill's Island 3 can already house as many as 10 million people as is. If you want more real estate, balanced with manageable populations, build more habitats. There are no limits to the number.

[@smallpeople172]

Bro you can catch rays from a central tube since carbon nanotubes perfectly match the suns spectrum as we get it here on earth’s surface

[@spaceboffin]

It's only about 1000 square km. Like a square plot of land 20 miles / 30 km on a side.

[@Cyberwar101]

You can replicate the sunlight either artificially or you could have that light tube be made of reflective sunlight. For artificial sunlight, you can use something like a scalled up arc lamp, which puts out light that is very similar to natural sunlight. Or you could pump plasma not unlike the suns corona, within a transparent cylinder. As for capturing natural sunlight, you can have essentially fiber-optics that carry the suns natural light from outside the station, then shine them onto reflectors on the inside. Bottom line is that one shouldn't think of them like modern lighting. Replicating sunlight is doable, just not feasible for earth. So long as your brain is sufficiently tricked and you get some UV for your skin to absorb you should be fine.

These will be fantastically expensive to build, materially and time-wise. Every cubic metre will be pricey. Thus there won’t be unproductive open spaces or open volumes. We’ll start with unimaginative capsules like the ones currently envisioned for the ISS-replacements. As that form-factor gets entrenched steadily larger agglomerations of the same unit will come on-line. Stanford Toruses.. stack them up until they resemble O’Neill cylinders. There will be habitation zones, those far enough away from the axis for 1 G living. Closer to the axis will be food production with the hope that plants will be okay with less gravity. Small habitation sections nearer still for Mars and Moon gravity. Surrounding the axis will be surplus materials storage. Backup oxygen, nitrogen, minerals, water, preserved food, general stuff that are oblivious to the gravity they’re stored at. It will all be spinning inside a protective, non-spinning shell. The shell will be dominated by rock and water jacket layers, protection against collision and radiation. The outside will be studded by photovoltaics, rockets, communication antennas and radiators. The water jacket will serve simultaneous functions. The most obvious: radiation shielding. A few metres thick will protect the interior against cosmic rays. Also backup water supply in the very unlikely failure of water recycling systems. Lastly: thermal control. Kept at a steady 18 degrees Celsius it will steady the cylinder through infrared exchange. The jacket in turn will be thermally regulated with solar collectors and radiators on the outside of the shell. A decent sized cylinder, say 30 km long, 9 km diameter could accommodate hundreds of millions completely self-sufficiently. A similar capacity as a city-building 30km by 30km by 30 stories tall.

[@Cyberwar101]

The open space isnt really wasteful, as it can be used for a natural eater cycle. Also it isnt really all that materially expensive. Your average nickle-iron asteroid has plenty of material to build several of them. When you compare that to trying to terraform a planet, which is what is traditionally considered, the cost is trivial, even for equivalent surface area. Now, i agree that what you suggested would be more efficient. And doubtlessly that setup would be more common; however consider that it is also not the most efficient. If you want to talk about cheap and efficient, microgravity habitats are where it is at. Humans dont do well in microgravity, however the vast majority of the problems associated with microgravity are only problems if you want to head back to Earth. If you dont, most of the rest could be addressed. Thus anyone who can manage to adapt to living in microgravity full-time has a huge advantage. You dig into just about any asteroid, cook out some oxygen from the rock, and make sure its sealed, then just add more rooms and hallways as needed. Most of this could be done with tools no more advanced than what your average mechanic has on earth, and opens up the possibility of even single family habitats. There are some problems; we arent sure humans are fertile in microgravity or not, and bone density is a problem that can cause problems for kidneys. If some kind of gene therapy or medication could solve those issues, then I would expect that microgravity habitats would become the norm.

[@JFrazer4303]

Many details about it are fictional and somewhat fantastical, but the general idea is 100% realistic. It obviously wouldn't be "us" from down here, using tiny rockets based on WW2 long range artillery, building habitats for millions of people. The early first generation habs like the "Stanford Torus" or O'Neill "Island One" 800 meter sphere are ours within 30 years (anytime since the '70s) with no new inventions needed. No fantasy hand-waving "unobtainium" materials or sentient AI nanotech self-assemblers needed. Cost would be like many other large infrastructure or industrial developments down here. Any who disagree are invited to show their professional qualifications in mining, construction, and astronautical engineering and where they've been published under peer-review showing that the '70s NASA Ames space settlement studies were wrong. They found that the largest pressure vessels which we could build with known engineering were `30km diameter. Concrete and steel. With titanium (which isn't particularly rare up there, maybe twice that. Maybe 80 years after the first infrastructure and small habitats are done, there might be desire to make something so huge. By then, IDK what we'll be using for "cost" or "expense", because there is practically literally endless supply of energy and raw materials and things like previously rare or precious metals, in flying mountains, literally raining down on us as we sit. Very many much richer than the Moon, and very much easier to get to and get materials from. Habitats cannot be a long body rotating around its long axis, because that's inherently unstable, wanting to wobble and tumble and go end over end. Yes you can use various means to overcome this, but a smart engineer doesn't design in defiance of the physical laws and then apply complexity to overcome the design flaws. See the "Kalpana" space habitat, for the optimum: maybe half or 2/3 the diameter in length. With attention to making the rim massive, like a shallow drum or Torus. The aerospace vehicles inside it and the "gravity" defying architecture are as fanciful as is the supposed fusion power supply and the light emitter in the center. The O'Neill and NASA Ames designs planned for realistic warm (filtered) sunlight at "ground level", anywhere in the Solar system and out into the Oort cloud.

This colony, Sweetwater, was built by patching together a closed type to an open type and is therefore, very unstable. It was made hastily in order to accommodate those refugees, who had survived the past space wars. This was the only measure taken by the Earth Federation government. They concluded that everything was fine as long as they made a container to stick the refugees in. They remained on Earth and refused to share the planet. My father, Zeon Deikun, had made a request to Earth for autonomy for all space immigrants known as 'spacenoids', but he was assassinated by the Zabi family. The Zabis had called themselves the Principality of Zeon and it launched a war of independence against the Earth. You know how it was to end, with the Zabis losing the war, which sealed their fate. But the Earth's government had grown arrogant. The Federation forces had become corrupt from within, giving birth to rogue Federation movements like the Titans and resulting in the brazen activities of Haman, who had falsely claimed to be a protector of the Zabi family. This history has made us all refugees! What is our future reflecting on this tragic history? I firmly believe mankind must do everything to prevent war from rising up again. This is the true purpose behind our operation to drop Axis onto Earth. To change history, hence we will discipline the people who continue to live on Earth and eliminate the source of any wars in Earth's sphere! Everyone! So that we may forge our own path and establish a government for the refugees. I ask you, lend me your great strength for just a little while longer!

The soldier's fury at seeing this has to be seen to be believed, but what is interesting is how he describes conditions for Russian soldiers. For any who doubt that Ukrainians are having an impact (the Republicans) should see see this. But also, Biden could use this as propaganda. The second strand of the story is the poor girl who was in charge of the party. She posted 2 videos. In the first one she calmly apologises for the party. In the second she looks terrified. She is skeletal, and clearly official has got to her. She apologises profusely, and talks about deserving the death sentence.

Ask Chelyabinsk how safe any city on Earth is from a moderately small impactor. Ask any other city how likely it is. Space is not like an "asteroid swarm" in movies.

For the agents, I already reported the Green Brothers to the FBI over 5 years ago. What happened?

Maybe in 100,000AD

I bet somewhere sometime a thing like this was built. But us, na, no chance now. We have fucked our planet up. If we make it to farms and villages, we'll be lucky.

[@widyadwi321]

Then the colony got blow up by a bunch of ZAKU and DINN

[@Jay92master]

I'm 100% sure I'll take years. To build we need strong robots to build it for us. Don't rely on humans robots have ability to finish this oneil project colony

[@Patrick_Felipe]

Station like that has to be built in space…How do you get water in there? How do you get land or soil? If humanity lives on a colony like that its not by choice, maybe because earth is no longer habitable, its not gonna look like that, maybe more industrial, gritty all metal structure…

It would be a very complex job, involving super materials, exploration of moons and meteoroids, using autonomous mining and construction machines controlled by artificial intelligence, imagine that each ray of carbon nanotubes in this structure is 1 kilometer long, this would have to be done directly in space without direct interference from humans

​@@anthonykornhuerelbraonclan8041 Super materials are not necessary. This design needs no more than steel. Aluminum could go bigger due to less weight. Better materials like nylon for tensile strength could increase the size by a factor of ten. Nothing super about it.

Water is one of the most abundent things in the universe. You could get it from mining commets, saturns rings, skimming gas from venus, or simply burning oxygen and hydrogen, which are some of the most common elements in the universe. As for soil and land? You can grind up the rock and gravel of an asteroid, and mix in artificial fertilizer, along with microbes... Or you could process human waste with the regolith much the same way that some of our waste treatment plants on earth do. That makes soil which you could plant things. You are correct, however, that the bulk of the cost of such a structure is the bio-active dirt and soil. Most of the rest is a simple application of energy and manufacure, which is easy in economics of scale, but making all that soil would take rare elements like phosphorus and time. Also, i would absolutely live in a habitat like this. These things would have near perfect weather and temperatures, and are almost totally self sufficient. They could indefinitely support millions of people with almost no imports for thousands of years.

the stutter framerate makes me nauseous

[@massimookissed1023]

Well then, *_you_* get to stay on Earth, 'coz we don't want people with weak stomachs flying through space on their way to the cylinders.

Ayo, anyone thinking what I’m thinking? Sieg Zeon!!

Ну да в трубе живём зато все счастливы,здоровы так и труба с тобой и сомной .😂🇷🇺☝

Is building an O’Neil cylinder the cure to male loneliness ?

[@Jay92master]

This oneil cylinder is better
