I did have an idea once that it would be really funny if we built a series of orbital rings or something similar so you could have a literal stairway to the heavens (or ladder). I think it would be really interesting to see what the fastest climb you could do would be. Also, if it would be possible to carry all your supplies otherwise you'd need little moments of traveling in to shops and snacking/finding a place to rest before continuing your climb. There's probably a cool sci-fi story in there somewhere.

"The Fountains of Paradise" is a really good sci-fi book about building the first Space Elevator. It examines how the first filament is made and installed, how it would be possible to make it in zero gravity, how descending elevators would produce enough power to charge the ascending ones ; it's a good read. Eventually over the centuries, mankind builds a whole bunch of them along the equator and joins them up into a massive ring in space. By that time , the filaments have been replaced by actual buildings and people commute regularly into space for business and recreation.

I did a group project some years back designing a space elevator for the Moon. While the strength requirement for a Moon space elevator is much less than for the Earth, only the strongest material like kevlar or carbon fiber stood a chance. Unfortunately you need a cable twice as long for the Moon as compared for the Earth. Also we did some studies on the dynamic stability of the elevator... Spoilers: its not great. It can be made more stable by increasing the mass of the counterweight but making the whole system absurdly heavy

[@travcollier]

But for the Moon we can just use linear accelerators / rail guns. Lower gravity and minimal atmosphere is helpful.

[@Di66en6ion]

Seem to remember that there were calculations done that a tether at geostationary orbit would end up intersecting, at some point, any trash, debris, or other satellites at a similar latitude. Our space junk would make it impossible or prone to failure.

[@blockchaaain]

It is virtually necessary to put the elevator at the equator. In which case, every satellite (below GEO) will intersect it eventually.

[@Respectable_Username]

That's not an impossibility; that's an engineering challenge! How to make the cable both resistant and redundant enough to withstand collisions when they do happen, not to mention (in the decades it'll take to actually build this) setting up rules, either in law or just by practical consensus, that active satellites _must_ adjust their paths to avoid the space elevator and non-active ones in that zone will need to be fully decommissioned and removed from orbit, reducing the frequency of collisions that need to be withstood. And then of course comes the challenge of repairs. The cable _will_ get hit and _will_ get damaged, so how does that damage get repaired such that the wear and tear doesn't build up enough to cause catastrophic failure? That's yet another engineering challenge, but one I'm sure will be worked on once we've figured out the actual cabling if it hasn't started already. And, of course, getting systems in place to deal with catastrophic failure to fail safely, both for those riding the cable if it's severed and for those on the counterweight base station. Difficult challenges for sure, but _far_ from impossible! That's what engineering is all about 😊

[@Di66en6ion]

@@Respectable_Username Pretty big engineering ask, especially when collisions at that speed are probably impossible to deflect completely. No material that could ever be engineered at that shape and scale would resist an object traveling 10s of thousands of miles per hour. Your best hope would be a material that doesn't catestrophicaply fail under tension along with backup tethers or bots that can nudge and weave the cable out of the way of debris. Cleaning up the orbit seems like a potentially more approachable method but that's also a huge ask. Either way it'll probably cost more to implement than humanity has spent on space exploration to date, combined.

[@Respectable_Username]

@@Di66en6ion Oh you misunderstand: The goal isn't to prevent any damage from occurring but in stead break gracefully in such a way as to not harm the overall structural integrity of the, well, structure. Think fibreglass: Normal glass, when broken, will shatter and completely destroy itself. However, by weaving together a whole bunch of teeny tiny glass strands into a mesh, you retain a lot of the beneficial strength properties of glass yet cracks can no longer propagate like they can in a pane. This means that the mesh can have many small holes in it without decreasing the overall integrity of the mesh too much, and those holes can then be patched during maintenance. Obviously I'm not suggesting fibreglass for the cable, but a similar principle, if it can be done with supermaterials such as carbon nanotubes (requires a lot more research for that to be possible, but the research is ongoing!) would allow the cable to take a hit or even many hits without severing. The paper I first heard about space elevators from proposed a more ribbon-like cable than a tube-like cable, which means the point of failure isn't as concentrated into one location amongst other benefits I can't quite remember (it was a while ago). Obviously impacts from larger debris can still cause catastrophic failure, but those events are much rarer and need to be accounted for and mitigated with other techniques. The average small debris though can punch through a small cross-section of the cable and leave the rest intact until routine maintenance comes along to patch said holes.

[@Vastin]

Satellites would have to be maneuvered to avoid it on rare occasion - and yes, you'd need to clean up LOE. You also need some means of repairing the strands in place, or be frequently running new ones in order to reinforce/replace them as they inevitably get dinged up. You can run new tether elements up via the elevators themselves (in pieces), then connect them at a fab in orbit and lower them - in principle. This whole thing requires a great deal of materials and engineer capability that we do not currently possess, and some elements of which might prove to be impossible if we're unlucky.

[@Ragetiger1]

Only real downside to this would be the constant replacement of that cable. Since it will be subjected to friction from the elevator and exposure from the elements.

When the lift breaks down, thats gonna be on hell of a fall

[@2testtest2]

I take issue with the statement about sending things to space without a single drop of rocketfuel. A Space elevator like this colud only deliver objects to space without rocket fuel in a very limited set of orbits, the biggest of which would be Geostationary, and every lower orbit being increasingly eliptical, with the apospsis where it was dropped of the elevator. Without a plane change maneuver it would collide with the elevator once every orbit. Also every time you hoist something up there, you rob the counterweight of a little bit of angular momentum, which will need to be replenished every once in a while.

[@lb5299]

You don't rob the counterweight of angular momentum, you steal the Earth's rotation angular momentum. I don't know if that makes it better or worse

[@2testtest2]

@@lb5299 I see my choice of words might have not been the best. The earth will indeed be robbed of angular momentum, but I figured it would be negligable considering the enormous mass of the earth. For the counterweight I was considering its angular momentum about the center of the earth. Since angular momentum must always be conserved, hoisting a payload up and accelerating it to orbital speed, it has to take this from elsewhere. Now for simplicity sake consider the rope as a stiff rod, connect by a hinge at either end. As the payload is hoisted up, it gradually its orbital speed is gradually increased. This acceleration must be accompanied by a force perpendicular to the rope. In order for the rod not to receive an angular acceleration from this force, it has to be pushed by the earth and the counterweight at either end. When it is close to the earth, it's mostly the earth providing the force, but as it ascends the force gradually shifts towards the counterweight. Therefore both the earth and the counterweight must be slowed down.

[@stereoroid]

The point of the counterweight is to keep the whole elevator’s centre of mass at the geostationary orbit. Another way to achieve the same result is to build the elevator up as well as down, and the further up you go past geostationary, the higher the linear velocity at the end. At geostationary (~36,000 km) it’s just over 3 km/s, at 60,000 km it would be over 4.8 km/s.

[@Respectable_Username]

Also, you're confusing the need for "propulsion" with a need for "rocket fuel". One of the advantages of the space elevator concept is reducing the power requirements to change altitude, which means non-rocket fuel energy sources can be used for this propulsion. Notably, any propulsion method that primarily uses electricity as its power source, which can be easily collected from the sun once beyond earth's cloud cover and even easier once beyond the majority of earth's atmosphere. Once you're not needing to reach literal escape velocity to move upwards, the amount of power (that is, energy over time) you need is _much_ smaller, and so chemical propellants, particularly petroleum-based propellants, are no longer necessary! Not to mention the simple energy saving of not needing to move the mass of the fuel that's powering that movement. There's also more exotic propulsion methods like sun sails that could be strategically deployed for an effectively "free" adjustment in angular velocity, although I'm not sure those have been tested in practice yet or would still work in the small amount of atmosphere that remains around geostationary orbit and at the counterweight's orbit (which is beyond geostationary as geostationary is the *centre of mass* for the elevator, not its end)

[@2testtest2]

@@Respectable_Username Good points. I never said that there wouldn't be great savings with an elevator, just that it wouldn't completely remove the need for rocketfuel. Solar sails might be feasible. I'm pretty sure there has been one test in LEO, confirming the feasibility, though it wasn't able to overcome the orbital decay, just slow it down. You mentioned reaching escape velocity, but very few spacecraft ever reach escape velocity. The vast majority are destined for earth orbit, and thus must avoid reaching such speeds.

Great vid! Please more of this Space Technology Type 🎉

[@vanapotamus6348]

Thanks for the DIY tutorial very useful will use this to build a space elevator tomorrow

[@myloscoobdude6653]

Glad they added the banana fir scale otherwise i would never know how long 100km is

[@bloodgripen2257]

Id love to see some Ace Combat references in these shorts. *The Space Elevator, affectionately known as "The Lighthouse"*

[@_ThreeStrikes_]

I really hope so too

[@DerDonZottel]

„the Elevator-Kevin grabs a hold of it“ Can’t unhear this 😬

[@TsczhabyCC]

Alright lads, let's get to it

[@supercompooper]

I don't need this. I need a monorail to the fridge.

[@Maltbrew]

Now make a video on how big the space elevator should be

[@SkaiCyan]

You should do a video on the process of making diamond nano threads and why we've made so little.

[@fireswordfcyt171]

...but...what if something hit the cable? Even space dust would be enough to cut it in half, right?

[@traingod6248]

If we linked a space station to the ground then it would fall to the ground (if it does not snap it) because if needs to go very fast just to stay at that altitude

[@soacespacestation8556]

My guess for transporting humans using it is to build some sort of mall along the route to sell food, water and provide refuge from the 5 days of elevator music. Alternatively, you could just build the mall inside the elevator.

New ambition unlocked

[@jeffbenton6183]

5 whole days to get to GEO? On one hand, that sounds like it'd be less uncomfortable than the typical rocket ride, but on the other hand, it sounds like it could be even more terrifying.

Honestly the easier, and potentially cheaper, method might be to build a orbital ring and then build a space elevator attached to the ring. Orbital rings can be far FAR closer to the Earth and in turn allow us to use cheaper and more easily acquirable/manufacturable materials like kevlar or similar materials in both structures construction. TLDR: Build ring around Earth, attach cables from Earth to ring, and profit!

Mario glaxy reference (the mario planet) king kong (the ape on the crumbling tower) WallE reference (he flies through space with a fire extinguisher)

[@jaekoeb]

and a star wars reference with the worm thingy in the counterweight asteroid and the falcon flying by so much to discover in one short i love kurzgesagt

[@nolandonohue3514]

Hear me out, the main station should be the counter weight or at least extend in that direction

[@HammerMarc1895]

Terry Prachett wrote about the Space Elevator in 1999 in "The Science of Discworld". Very interesting read.

[@MalownMcOwnage]

His book Strata also mentions Space Elevators, ok the book is also weird

[@2p2e5]

The Fountains of Paradise by Arthur Clarke is the first novel to talk about it. It’s a great book, probably one of the best sci-fi novels of all time.

[@RRRV27]

Summer is here, I hope Phenious and Ferb are watching this youtube short

[@hyacinthsfae]

I'm dying that you included Banana for Scale reference, you never disappoint guys 💕

[@themosaicshow]

i always love the ‘banana for scale.’

[@--U--_--0--0--2--0--]

If it’s solar powered, at sunset it will just drop

[@LineOfThy]

Not how solar power works lol

[@--U--_--0--0--2--0--]

[@andrejmedvec6104]

Another way could be what spin launch does, it's more realistic, but is space elevator will be done, it will be more eficient

[@pannekoekcom4147]

It's all possible if the cable/elevator doesn't get hit by space derby

[@ogelsmogel]

Horses in space? Sign me up! 🏇🚀

[@casualobserver5124]

The importance of spelling debris made manifest.

[@summerblade3790]

Updated space elevator vid when? I wanna see details of the construction

[@LFTRnow]

But, why do *I* need one? This is gonna take a heck of a bite out of the monthly budget.

[@MyHogs]

Would also need the orbit where the cable runs to be clear of anything else, with all the stuff in orbit not happening.
