Can a space elevator be made out of a series of electromagnetically coupled solenoids?
Like build two things, a wide hollow tube that creates an electromagnetic field in it's center with North being up and South being down; and a smaller solid tube that generates an electromagnetic field around itself with north being down and South being up.
If you put two smaller tubes inside the bigger tubes with their ends meeting in the middle, the smaller tubes would be pushed out of the larger ones. Then you build a million of them and create a tower out of them. Would each tube act as an independent component, needing only enough force to push the upper tube up and the lower tube down, or would the force build up somewhere in the tower and cause it to collapse?
If each tube acts independently, you should be able to build a structure of arbitrary height given enough electrical power.
