Centrifugal Force: represents the effects of inertia that arise in connection with rotation and which are experienced as an outward force away from the center of rotation. Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. in this both Centripetal, and Centrifugal forces are at work. escape velocity depends on the angle at wich you are moving. if you are shooting straight up then yes you would need that high velocity. but if you have a craft that can get up to the altitude on standard rockets, once you got that high you can switch to a different type of propulsion and leave earth with out ever having to hit that high velocity. it would take longer sure, but wouldnt need all that fuel.

He describes this exact rig that is used to transport goods from the moon to earth. If it's ripped off from anywhere, it's there. @Merdril–It’s a concept explored by Robert Heinlein in “The Moon is a Harsh Mistress” written in 1966.

Study physics before you attempt to correct someone more knowledgeable than yourself. Joe, it is in fact centripetal.

What makes launching conventional rockets so expensive is taking fuel to lift the vehicle and the fuel for later on. Get rid of even one stage and the extra fuel needed to lift that fuel and you have a saved money, plus the reuse factor which might actually end up being good (as the Shuttle was supposed to be). Just to be picky and overall annoying, you can never leave the gravitational reach of any object. Escape velocity is the speed that you need to achieve so that you don't fall back. Also, the genius that brought up negative affects of magnetic fields on electronics, think for a second. Why would they already be in so far with this, all the money spent, without a way to get around that particular issue?

Its not impossible ..but you would need serious heat shields. To reach the speed needed to escape the earths gravity would you not have the same burn up problems , like on re-entry except in reverse.

But it's nice to start seeing ideas from modern science fiction come to reality. Maybe we can start building an actual Gundam instead of a limited functionality statue.

Nasa has technologies to keep space shuttles from burning up on re-entry. Why not wrap the pay load in the same type material. Also for another post. Who says it has tracks. It could possobly be floating in a magnetic field. Why would you float it miles in the sky. This is an experiment not an actual attempt at launching it into space. As the experiment progresses then that may be the goal. And I'm sure if they already achieve advertised speeds of 8km/sec then it probably can go much faster already.The US Air force isn't going to just give away all it's information for other nations to copy, and use against us. Also if it is wrapped in a material sensitive to magnetic fields that could burn off, and have a burn proof shield underneath then you wouldn't need a mag-lev, or balloon to launch it. It would take quite a large ballon or many multiple ballons to lift a million magnets or coils plus whatever else is involved that high into the sky. And a mag-lev elevator...come on homey if they had one of those then why would they need this for anything other than a weapon. Which is one the third reichs concepts,by the way, minus the magnets.
