The Space Elevator was Clark's idea. Copyrights belong to Science Channel, Discovery Communication LLC. Show your support, please subscribe to / sciencechannel
Russian rocket scientist Tsiolkovsky first published the idea for a *compression* space elevator is 1895. In 1959, Russian engineer Artsutanov published the first design for a tensile space elevator that we're familiar with today. The video is correct, but the post's description and some comments are incorrect: Clarke did not originate the idea -- but did help to popularize it and inspire millions.
One of the things I appreciate about Clarke the more of his stuff I read is that he had a vision of the future almost radically open to all. When I read his stories and reflect on my own, they suddenly seem almost claustrophobic in their scope and focus.
Think about it. Science fiction is a self fulfilling prophecy. Once you have an idea, engineers dreamt about it for decades and then create a device that matches the vision. Unless the ideas are in conflict with the laws of physics, eventually someone with enough resources would make these dreams come true. The SpaceX rockets that return to land were in SciFi movies date back to the early days of movie industry. Elon Musk's Hyperloop system was simply the same vacuum system that delivers cash from the cashiers to the back office in most Costco warehouses. They are not new ideas, just ancient concept that needs money to turn into reality. Clarke's idea will become reality sooner or later.
@@cplai it's less his tech that makes the day to me, honestly. Sure, eventually we can have _Rendezvous with Rama_ style rotating habitats- O'Neill worked out the parameters ages ago. But when listening to the audio version, what struck me was the conversations between characters. The discussion of faith, the openness and friendliness. It's present there, its present in _Hammer of God._ An acknowledgement that life in space would suck enough without having to worry about disliking the people you're with, too. The tech is all very cool- and will change everything. But it means nothing if we don't _all_ get to go up there. If we're stuck here while billionaires get to go up, it won't matter if we have a space elevator. Any 20-year-old just fresh from a physics A-Level and with an interest in space could have one up with a space elevator, or an O'Neill cylinder. But it was Clarke who popularised it, probably not because his idea was the first or the best, but because he was the first to popularise the idea in a way which made people sit up and take notice. It's like... You know how in TV shows the shorthand for being in Mexico is putting a weird yellow-orange tint over everything? His tint is optimism. He sails between gritty realism and Flash Gordon and makes something that I read and go "oh. Yes, if we had that future, it would be nice." And you're right. It's self-fulfilling. Instead of engineers working out if a Space Elevator is possible, though, its people reading a reprieve from the problems of today, and learning what a more ideal world looks like tomorrow.
A new space elevator concept will help to make us a true space faring civilization . It has multiple tethers at its center ( for greatest strength ) and fewer tethers as you move away from center ( for lesser amounts of mass ) . It is also in an elliptical geosynchronous orbit , so it appears to drop straight down from space , pick up a payload , and return to space , thus requiring a much smaller system than an earth based space elevator. We already have material strong enough to get us within the distance of the lunar gravity center ( around 6,000 mi. ) add the proposed system above and we could do this now! Let's get started. What do you think?
Jet propulsion cannot get you to the orbit. Even the latest Virgin Galactics' Spaceship Two requires a rocket second stage to push away from Earth's gravity. The spaceship is carried to high altitude by a jet powered first stage called White Knight Two. Then the spaceship is dropped right before the rocket fires.
A recent Apple TV+ SciFi series named "Foundation" feature a Space Elevator. The show is based on an Issac Asimov's novel from the 1940s. Now I am not sure whether Clarke or Asimov got the idea first.
A 22,000 mile space elevator (which would actually need a bunch of additional length as a counterweight) would have a high angular velocity at the far end and would give a spacecraft a huge boost when released, like a stone from a sling. You just have ro time the release to send the ship in the desired direction
What if the IDEAL length of the elevator surpass the space junk orbits? and how FAST coming DOWN to earth is going to be to prevent friction of HEAT? if the container CAN withstand the high heat, can the elevator itself hold that much heat created by the container that's coming down. If you do it slower......how long will it take?
True , Thank you , a few concerns though , who is going to pay for these elevators and which insurance companies will be willing to offer work safety compensations for such projects and lastly , who would be willing to take these task of building these elevators ?
There's better shit than oil. It's called Helium 3, a special isotope of helium that can provide nuclear energy without radiation and there's a shitload of it on the Moon =) PS. They should explore using Aluminum cables for the elevator because it get's stronger in the cold and can carry current to power the motors on the cable car.
One big problem would be piercing the ionosphere with a cable. Doing this would send a 20 terra watt electric charge down the tether to earth, instantly vaporizing the cable. It would be like driving a nail through a lithium ion battery but on a grand scale.
Part of the (let's remember this is all speculation, people) for elevators would be to make rockets and their pollution, unnecessary. This is for a time when as many people move from Earth to space every day, as now commute back and forth from NYC. Plus freight. Masses and masses of people.

Now world need that one
if there is oil on the moon there would be already 1 from the 80s lol

Very Interesting Idea!🤔👨🚀🚀🛰🌌
Keep in mind in high mountains, oxygen rarifies 😋
22 miles elevator will make possible exploration of space ? Hundreds of lightyears around... 🤔Curious to see that happening, very interesting though.

Reminds me Transformers: Cybertron
How do you solve space JUNK? that very likely going to damage the elevator
Just stay below their orbits. :-)
What if the IDEAL length of the elevator surpass the space junk orbits? and how FAST coming DOWN to earth is going to be to prevent friction of HEAT? if the container CAN withstand the high heat, can the elevator itself hold that much heat created by the container that's coming down.

@@cplai. yeah true, but what about space rock pebbles, just one would be more then enough to completely destroy a space elevator

Easy: Think military. Look at all the advanced innovations, almost all with some level of military funding...

source bro
I doubt the charges would be that great, but there would be some static charges that needed to be grounded to prevent them from building up
what about space rock pebbles, just one would be more then enough to completely destroy a space elevator

There are also those tens of thousands micro satellites sent up by Elon Musk.
Here's another train of thought:

I find jet propulsion easier ,
Part of the (let's remember this is all speculation, people) for elevators would be to make rockets and their pollution, unnecessary.
