SPACE ELEVATOR FIRST FLOOR 22,000 MILES UP

[MrJuno6]

Why a "guidance system" its just a lift is it not ? which seems to imply just up and down.

[yamahaeleven]

@MrJuno6

The vehicle rotates and undergoes various oscillations along with the cable, and the lasers aren't directly in line of the climber's travel. A guidance system for the laser is mandatory to compensate and keep the beam accurately on the receiver cells.

i hate whiteys

[yamahaeleven]

Yeah, they seem to be stale often.

[curvygirl1123]

so if the first floor is 22 thousand miles above the earth were would the 11th floor be

[yamahaeleven]

Kuiper belt.

[curvygirl1123]

thankyou

[nazsh11]

22,000 is a geosyncronous orbit, thats what would give it the most stability. but any kind of structural failure would be catastrophic on both ends.

fffaaaagggg

[deventimothybryant]

carbon nano tubes baby. there's a research group here at he UW im trying to get with more efficient ways of growing them. neat stuff!

[BaronVonKenny]

Why dont they start it on something tall like the empire state building its already close to space man!!!!

[JC23333]

not a bad idead you have worry about the stabilty

[BaronVonKenny]

the empire state building is stable enough for space man, didn't you see that documentary where the giant peach landed on top of it? If that dont knock it down, then the moon aint got shit on it man!

[JC23333]

nah but you gotta worry about wind speed and all dat why dont they just sticka rope to a rocket lol no im serious

[Martin140189]

It has to be on the equator!

[ogicabp4u]

no it doesnt. Do the maths...this is simple trigonometry. Its better nearer the equator but it does not have to be on it by any means!

[chessami92]

you are very unintelligent

the empire state building is 1453 feet tall and there are 5280 feet in a mile

we need to go ~22000 miles to get to outer space

as you can see, the empire state building is nothing on this journey

and yes it does need to be on the equator

[BaronVonKenny]

You are very stupid if you believe my comment was serious, I was joking around. This guy is a psycho, look at his other vids, I bet he broke into this place to film it.

[haggardjf]

can it go to 11?

[yamahaeleven]

no, it has to be in bed by 10.

[JC23333]

wolly lol

[hotcobraguy2001]

Its 100 km or 62.1 miles straight up from sea level.

22.000 you are a fool read man read

[03cammd79]

yea, its crap

[yamahaeleven]

it could work if the material used for the space elevator can have a strength above 120Gpa. Which isn't likely, so the idea can only be used on a different planet or moon with less than half earth gravity.

[yamahaeleven]

That is easily the greatest challenge, besides coming up with strong enough material, for a space elevator. The current thinking is to have sufficient repair capacity to mitigate impact degradation.

[salemcripple]

Have they solved the problem of space junk yet? Last i heard they didn't know how they were going to avoid tiny shards of what usto bee satilites, ect. from tearing through the elevator, and or nanotube cable.

[yamahaeleven]

You are correct. As a frontier, many things will need to be imported from earth, even though space pioneers will "live off the land." As time goes on, this will diminish, then the technology created in space will far exceed terrestrial technology.

[NonTheist]

Space elevators are sweet, I heard they are working on carbon nanotubes formed into a ribbon for the rope extending into orbit, its all awesome stuff.

[yamahaeleven]

Just don't buy any rides on one, the radiation in the Van Allen belts would kill you outright on such a slow trip. Have to wait until they are big enough to take a huge amount of shielding.

[NonTheist]

I guess, if you want to go further than the space shuttle you would have to worry about that, but getting to where the shuttle goes would be good enough for me.

[yamahaeleven]

Still be safer to use a rocket, like Space Ship One that won the X-Prize.

I'm involved in this project primarily to be around the super powerful laser, that is what will really get us into space, eventually.

[yamahaeleven]

The space elevator is solving a problem we don't have yet, and may never have, that is getting really heavy payloads up from earth. If you were to simply use the plentiful resources available in space, no need to bring so much with you.

[GuiltySpark347]

woow o ya center of mass?.

[irelandsfaint3]

oh, so it'll move just a tad bit, not enough to kill everyone

[yamahaeleven]

Although, if you use it too much, the earth's rotation will slow down, and in a few billion years, we'd all be baked on one side and frozen on the other.

[irelandsfaint3]

Great!, but what if the elevator knocks earth out of orbit?

[yamahaeleven]

Earth mass = 6.0 x 10^24 kg, mass of the largest space elevator = 6 x 10^8 kg. The earth is 10^16 more massive, so about 10 million billion times more massive. Therefore, the space elevator may change the center of the earth - moon system by about a trillion - trillionth of a meter or so. Run for your lives!

[ourben]

I love that question, someone always asks don't they? hahaha...

[yamahaeleven]

Better safe than sorry!
