What we can measure for Carbon Nanotubes, if we could actually build them to a reasonable volume and length, it would absolutely be possible to build Earth's Many, many Space Elevator cables While Space Elevators are conceptually envisioned as solely Equatorial constructions, thats incorrect. Once the counterweight is in position, it can be used to anchor any number of space elevator cables to the hemisphere of its Line of Sight. In fact, When it is built for real, the Counterweights will be positioned over India and the Atlantic, So you could theoretically embark on an elevator in Syndey, Australia, and with some transit as the counterweight, them embark on the elevator to Athens, Greece.

Mr. Shack, that is the standard answer to what is holding back building a Space Elevator. While super materials do need researching it's not actually true it's keeping mankind from building one. A super strong connection is dependent on the design of the elevator and hundreds of other factors. It's possible to design a working Space Elevator with variable requirements and capabilities. Like most successful inventions the first working one should be a small prototype to test and measure for what is to follow. Skyscrapers for instance were iterations of success as most things are. So we're telephones, planes, ships, etc. First just do it, then elaborate and improve.

Go ahead and carefully measure the movement of the planets, stars, sun, and moon - something that has been done for many thousands of years. Expensive equipment can be helpful, but isn't required.

Wikipedia has the math for a Mars tether. A Moon tether is not possible in the traditional sense, where the cable is supported by centrifugal force, because the Moon spins too slowly. It is however possible by extending a cable from the L1 and L2 point, and taking advantage of the Earth's gravitation to maintain a stable cable. In fact, the Moon tether can be built with Kevlar and represents a space elevator we could actually build with today's technology.

I'm glad you touched on the space debris aspect. We would definitely have to ensure there were no uncontrolled objects in orbits that could intersect with its path before it could be feasible. I think there are 90,000 objects currently being tracked, plus many more that are too small to track. This makes me skeptical that space elevators will be feasible any time soon. Also, if we can crack fully reusable rockets, the advantages of space elevators may be a lot less then the proponents would like us to believe.

other less discussed issues on space elevators is variable amounts of drag along the due to variable weather and increasing altitude, and whether it can properly resist or transmit thermal heating from friction and electric magnetic effects which snapped a multi mile long tether experiment on a space shuttle mission, and what kind of impact if any such a megastructure could have on earth/solar interactions, and what kind of tidal loading are earth, moon, sun interactions going to put on it; and whether micro organisms carried by the rain would colonize and begin eating the yummy line at the bottom, and how the top could survive contact with natural or unmanned space debris. The benefit of most space craft is that you don't get sea barnacles trying to grow on them, and if they are in danger you can boost them to a different orbit. This one is anchored. Actively defending the structure from "the elements" could be cost prohibitive even if building it is not.

From what I understand moon space elevator is possible with today's technology and is actually easier to build because the moon is tidally locked. you have to put the satellite at the Earth-moon L1 and balance it there. But compensating for tides shouldn't be that much of an issue. you could either use thrusters or simply change your center of gravity by moving the counterweight up and down. But everything else is an issue. And weathering, needs to deal with space weather as well. It has to deal with the solar wind and the environment in the van allen belts. A more serious challenge though would be the winds. Any force acting on the cable inside the atmosphere would be propagated through the cable to the space station which would need to constantly mitigate for it. As for space debris I do imagine one might mitigate this by having a mobile base, which can change position to avoid collisions. One imagines this could be achieved by moving the base and the station in a coordinated fashion along the equator line, but now you have another factor to consider: waves. Still, I think all this can be solved in software. It does pose another problem though: when the base and station move to avoid collision, this induces extra strain on the cable, which will lag behind due to inertia, so you'd have to factor that in the design. As for erosion due to either lifeforms or weathering one does need to factor in the possibility of maintenance. And this is one structure you can't afford to neglect for a few thousand years, like the pyramids, as it would come crashing down on the planet.

So what I saw in the anime; Gundam OO (Double O), the animators and designers were on to something when they made the orbital elevators in the anime? We just need better materials to make it work? Mind blown. And here I thought that the Japanese have a hard on for space elevators when they kept putting them in their animes...

Just a small correction: the reason super tall buildings have a wide base and nonprismatic narrowing shape is not to reduce total gravity load, but to combat coherent vortex shedding -- where wind forces become amplified at a specific frequency. Primarily that, but also to reduce overturning moments via lengthening your moment arm. An additional factor is you have less surface area at the upper stories driving up base overturning wind moments. You could theoretically build a square super tall building in a vacuum without issue. You'd simply have more large columns.

The After Effects work in this video is incredible!

Thank you so much for adding references to this; these videos are a great overview for research, so having sources is super useful.

sir - this is only the third of your KZread postings I've watched and I've decided to subscribe. I want to go off and do "some algebra" and determine the "altitude" of the counterweight where the centrifugal force exceeds gravity at that altitude to provide an acceleration of one g. Perhaps you will do the same. That would seem to be the best altitude for the counterweight. Right now I don't know what the mass of the counterweight would have to be at that altitude to balance the effective weight of the cable system from the space station / satellite at geostationary altitude down to the surface. I will check for more of your postings in this series since you may have done such calculations.

Orbital rings are where it's at. You can buld them just a few 100km up, meaning you can make the cables out of things like Kevlar, and they are much more versatile as they can actually launch and catch spaceships and send them out to the moon or even interplanetary.

@UCe2tjdUskfhS8yFg8wh67_A I recommend watching Isaac Arthur's video on the subject of orbital rings. Basically as you say, the rings do need to feature a rapidly spinning internal mass running entire its lengh to counteract gravity. This internal mass is basically just a metal cable, with relatively mundane specific strength requirements. Imagine this cable spins at 2x orbital velocity for its altitude, and you can see that the such a cable could support either continous weight along its entire length, or descrete points a long its orbit where structures could be built, or relatively short tethers lowered down to the planet for stability and lifting things into space.

I'm currently doing my master's in materials science. Love your videos, mate! Keep up the good work!

Or 'Love in an elevator' for the couples who go up

gundam gn-000 wonderfully displayed the space elevator concept to me as a kid then later Isaac arthur elaborated on it i like the active support concept for space elevators.

One amazing way of applying this and other related knowledge I've found was the book "seven eves" by Neal Stephenson It's a realistic (or as close to as far as I understand it) scifi book where the earth's surface becomes uninhabitable for several hundreds of years Humanity gets about a two year head start, and immediately starts flinging stuff into space (It's set in a vague near future where the ISS is a lot bigger already) anyway, difficulties ensue, there's a timeskip in the book, and we see a society living in orbit around earth, slowly building its way back down. one of the ways these people get from the planets surface to space is this: you get a powered glider, fly into the higher atmosphere, where you reach the lower end of a spinning satelite. this satelite is essentially two pods on a REALY long string that spin in a geostationary orbit, just at the edge of the atmosphere. once your pod is pointing "up" (away from earth) you're in the lower bounds of space, and you can use a different means of getting into a "propper" orbit. Mind, this was all written from memory, so I might've missed a step or two, and I'm not a professional writer, so my descriptions aren't the greatest. but if this sort of stuff seems interesting I can really recommend it!

the sky hook sounds much more feasible.

11:00 and we shouldn't forget the chemistry. The material should be inert to corrosion or at least be shielded against the temperature ramps, humidity and other chemical corrosion.

Two points, 1) the taper ratio does not need to be accomplished with just one fat tether. It could be done in stages with multiple tethers. 2) he says the orbit cannot be elliptical but if it was and the lower end was not attached to the earth it would just bob up and down. If at perigee it dropped into the atmosphere you could attach your payload from a plane and let the elliptical orbit lift the payload without a need to climb the tether.

It won't wrap around if it has the same angular velocity as the Earth. Also if you tether it from multiple points, you don't need it to be tethered at the equator. Also it won't be in orbit bc it won't be free falling. If anything, we'll have to reorient satellite orbits to avoid hitting the tether at a huge relative velocity. Isaac Arthur's channel goes over orbital elevators quite nicely.

As an Ace Combat fan, I truly hope that we make one.

@70 Roadrunner btw, if you want to take the idea of space elevators seriously you must consider the idea of launching the cargo at a high enough altitude and then letting the elevator do its job. Or else its all impossible. The idea of space elevators on earth is too good to be real. We could make a moon elevator at some point but not anytime soon

8:03 T is such a nice guy!

apart from materials problem, its also action and reaction, as cargo climbs up, it'll pulls orbital station+rope lower

First. We make multiple towers. Many. We put the motor the carries the cables up at the top of most. We use shorter cables. You go up one tower. Now you attach to cables on the other tower. We use mount everest as a starting point. So at the peak we build a huge thing that goes up from there and also sideways and we have many pillars connecting to the main beans that head horizontal from the peak of Everest in multiple directions.

The height visualizations in this video are a bit misleading. The geostationary orbit you are talking about, is almost 100 times higher than the ISS (400 km). In the images here the orbit looks almost like LEO (low earth orbit). Geostationary orbit is almost at 3 times the diameter of the earth (12,700 km)

Assuming the materials exist to creat this structure we will need to build several “strands” out to the counterweight so cargo can move up and down simultaneously. Transit time has to be taken into account also. Traveling thousands of miles will take time. Multiple strands will allow separate loads running at different speeds. Express for people to minimize time and more leisurely rates for cargo determined by most cost efficient power requirements.

Can you imagine the view of the earth as you went up that elevator? Holy moly.

A layman question: What about the velocity? ... If a mass is lifted up, it will 'drag' the cable/station. You need to 'accelerate' the mass horizontaly, from the 'ground-speed' to the speed of the station.
