Space elevator 1000 foot climb test

[adelle0001]

totoo ba to?

[FirstBatalion]

Thats not a space elevator! thats a balloon! and people thought i was stupid.

[Pimp1nSmurf]

LOL @ anyone who doesnt know what these guys are doing. What are you a caveman? Natural selection hasnt weeded you out yet? I vote we remove warning labels from all products and let natural selection take its course.

[tgoolsby2]

what is the ribbon made out of?

[ataraxic89]

@tgoolsby2 this is just plastic, the real one will be Carbon Nanotube and will be perfectly taught i think, it will be about 62k miles long.

[redelman43199]

@tgoolsby2 The projected space elevator idea would use carbon nanotube.

[ANDREWWALLFORD123]

More careful, what could be affect looks like a UFO ball of chaseing other people to show on.

[Flashlight1996]

Anybody mind explaining what the fuck is going on?

[librano]

Why aren't you guys using metric... I have no idea of the heights you're talking about... argh.

[hardstyle905]

@librano yeah, imperial american shit sucks. But Americans are so obsessed with being "different" to Europeans, even though they steal our technology. Fuck them.

[Tlachball]

SEs would be anchored to floating platforms at sea on the equator avoiding most weather and traffic.

[bhvmaia]

The fascination with a flat ribbon is illogical. Wind would be prohibitively strong on such a length, a ribbon would buck and whip madly, and jetstream would rip it to shreds. And just imagine the capsule ride! An elliptical cross-section rope would have least wind-resistance, and ample traction would come from passing over many wheels. Popular media must move away from the flat ribbon model, it is irrational and costs our credibility..

[pugNdrum]

thats f***ed up srrsly it stopped getting realistic at the mile high tower or the burj dubai but this is stupid ! :(

[903harman]

@pugNdrum its going to save fuel for liftoff...

[MantisAtlantis]

Keep at it guys! Fantastic and cost effective method of transporting people and materials to space.

[ceebo100]

This is a good idea yet so silly.. all it would take is one person with a snier rifle to keep shooting and wreck the cable.. worse still.. some suicide bomber or what not to fly a small private plane into it.

Any type of storm > high winds > earthquake or other forms of natural courses would also put the cable under massive preassure. Its not like a wall.. if it falls you cant so easily build it up again.

[shakenama]

Really neat stuff.

Basically 3 hurdles to overcome.

1. Currently there are no material known that is strong enough to support the heavy loads, passengers and a satellite.

2. The millions of pieces of space junk which has to be dealt with to prevent the elevator from getting clobbered.

3. the cost... a recent estimate places the cost to $20B..yes..billion -likely several private enterprises to help.

ok...side question...

Would the cable travelling through the atmosphere effect the cable?

[903harman]

@shakenama they build it with nano carbons.. that is strong enough <.<

2.the elevator is extended into space and it travels with earth the speed will support it

[YukonTrooper]

Good stuff. The balloon as a crutch takes a little out of the excitement, but the process of learning is more important than anything else. Keep up the good work.

[Sledkid15]

are they realy going to come through with the space elevator for the future?

[wildboy789789]

yes... nasa is working on it and offering alot of money to anyone that builds it

then they are going to start working on space stations that circle the top of the elevator for offices and appartments

im excited :) but scared to go up that high :(

[jussipejulliano]

0omg!! aliens!!

[ascendrian]

Keep up the good work on the space elevator... :)

[vuetube]

Babel II

[barolfe]

Clearly you have no idea what is going on here. That's ok. Stay ignorant.

[TheDarkFalcon]

man you're stupid

[Keepemout]

The mains problems for space elevators is that of thermodynamics. A cable will stretch and contract from thermodynamic forces - not only by friction at the subatomic level, but at the gravity stress level as well. When ever you make something thin and long, there are always unforeseen problems. Also when something this long and thin is implemented, even the passing of a comet could stress the cable one way or another by inches.

[sacha4you]

Keepmount, I think, you wanted to mention thermal expansion. Well, since relative lenght changes are in the range of 1E-6/K, there is no major problem. Also meteorites can be neglegted. The really big problem is the weight. Since centripetal force goes with r^2, most of the cable's weight (rGEO=36'000km) can not be compensated. Then there is the energy problem: E=m·g·h. So the idea is nice, but technically questionable. A gravitomagnetic drive would do a much better job!

;-))

[WolYou]

Gravitomagnetic drives are a bit out of reach.

[sacha4you]

WolYou, sorry to tell you, but I'm working on it for my university, and I can tell you, since about 2006 [Tajmar/Matos ARC/ESA gravitomagnetic London moment experiment] we will have rather soonly useful GM drives. Sandia is currently developing low neutronicity, direct electricity conversion pulsed plasma fusion power plants [+H+B->e-]

so in a few years, these things will be available for civilian use too.

;-))

[moblehomephysicist]

cool, but at what weight does the satellite that it will be hooked to eventually support..theoreticaly it might pull the satillite out of orbit..but cool vid anyway...i have some alternitives on my vids...but either way we go into space....there has to be a cheaper way than the way we do it now, rockets cost way to much to lift off..

[terrasidius]

cool!

[djcellx]

i like it,i dont no why,but i like it

[kelaanz]

read "about this video" for it to make sense

[ibo2147]

so which i learned this tests : ribbon breaks

[BorderInspector]

this ribbon is stronger than steel.

[evensgrey]

The ribbon on the real structure is stronger than steel.

I saw a LiftPort presentation that covered the planning for this test, and they were planning on using dry wall tape for the test ribbon, since it's plenty strong enough for the distances involved, at least it is if it isn't chemically damaged.

The real structure will use carbon nanotube ribbon, which is comfortably stronger than steel (which I understand you could use, if you made the entire structure much thinner as you go down).

Humans are strange animals

[bermudarailway]

I think we're all mad.

[SolidSnake032486]

@mistermizu It's just called curiosity.
