Japanese Company Plans To Build A Space Elevator By 2050

Image credit: Glen Clovis

Japanese company Obayashi has announced that they will have a space elevator constructed by 2050. The elevator will reach 96,000 km (60,000 mi) into space and will transport people and cargo to a new space station. It will also serve as a port to transport astronauts to Mars and beyond. Watch the video below to learn more about their concept.

“The construction process consists of deploying the cable and constructing the facilities. It is necessary to analyze the cable dynamics in order to estimate the characteristics of the cable, counter-weight, facilities and climbers, and in order to determine the construction procedures. Parameters for the cable dynamics include tension, displacement and elongation of the cable due to ascending climbers, masses of counter-weight and cable, wind, and fixed loads of facilities. With the help of a computer simulation of the equations of motion, we designed the system and determined the construction process.” ~ Obayashi

We cannot even manage our affairs here on earth, why do we want to muck up the Universe?

what happen when the cable break, it will go to all nations

If the cable failed, it would not fall vertically, but would wrap around the equator. The final stages of the fall would cause damage on the scale of an asteroid strike. The chances are that, during the final stages, anyone who could see the fall would not survive it.

Probably that is why the base station is set up amidst the waters to reduce the strike impact to the earth rendering the travellers safe up to some extent. Parachutes may also be employed for such mishappening within earth’s influence, I suppose.

That would be the biggest short circuit in history of mankind 🙂

They’ll need to get some basic science right first. Space begins at about 100km. The International Space Station orbits at about 408km. 96,000 km for the space elevator seems like a bit of an overshoot.

Basic science dictates that a space station that could have a space elevator must be in geostationary orbit, which is 35 000 km away from earth. Given that the cable would at least be twice the lenth of that distance, their estimate doesn’t seem too far off. Considering that the cable wouldn’t be completely straight, that you need winching and braking mechanisms, I believe they’ve made some resonable choices.

I’m more curious about what the cable would be made of, since it’s weight would be prodigious.

si je dit pas de bêtise, les scientifique sont entrains de créez des fils en carbon en nano technologie et j’avait entendu de ce projet qu’il arriverai peut être a créez un câble en carbon incassable pour 2050 ! A voir si il font chiez à ce cassez le cu a continuer alors que d’ici (quelque année) la technologie aura encore pris une avancée majeur , imaginez dans 30 ans ^^ ….

Its impossible to overcome the rotational and revolutionary motions of earth if they really want to construct a cable-based elevator

far from impossible. the science was done already, 50 years ago, and the project given up, since the only material strong and light enough for the cable was diamond. we might have new materials today that might make it possible again. placing a counterweight far enough out, makes this workable.

the cable is a wire that is cutting a magnetic field every time the earth turns…..electricity will be created and amassed in the cable. If I remember right, some country did something like this already and the cable eventually amassed so much charge it melted and snapped! If anyone is going to figure out how to harvest energy from the earths movement, it’ll be the Japanese!

And right now someone is trying to figure out how to weaponize this.

Why have a physical cable if you can make a beam of energy for objects to hook into and ride up? It would require a lot of energy, but probably less than actually making a huge cable and shooting it into space.
