I have a elevator question . A cable will be stronger enough to reach the atmosphere before it will have the strength to reach earth . How far can it reach now is there any thing to harvest there ? How far do we have to reach into the atmosphere to make it worth wile to harvest? In my mined I hope for a gas station in orbit. I have know idea if it is silly thought or not.

What materials will the ribben be made of and how will it function i wonder?Can magnetic energy be used for movement. maybea saucer shaped .how does a telsa coil and wireless power work in space?

The ribbon will (currently) be made out of carbon nano tubes, which is the only material that has the tensile strength. The problem is creating such a long ribbon out of this material which is problematic as of now.

The load must still be traveling hundreds of miles an hour to leave the atmosphere. Nice try, retards.

spacetruth, thank you for your post which shows complete ignorance of physics -- You are almost certainly trying to refer to escape velocity, which is the initial speed required for a body to reach and infinite point with a speed near zero after escaping from a source of gravity.

The difference is that escape velocity only applies to objects that:
A) Do not have their own source of continued propulsion
B) Can not take advantage of other forces (such as gravity slingshots) to assist in their escape

Any object which can maintain upward velocity (regardless of how slow) after accounting for atmospheric drag and gravity can make it into space. There is not some magic barrier in the upper atmosphere that requires you to reach a certain speed to break through it.

Where can I fiend the reasoning behind requirements for the SE?
I read that space starts 100 km from earth, why then it has to go 100000 km?
why cant conventional steel or concrete structure work? edited 16:46, 20 Jul 2010
