I wonder if this could be used to make an elevator to space, since it could actually travel very far upward distances without having to deal with cables? It would save so much money in terms of rocket launches and people could enter and leave space with very little effort! But it would probably take some major feats to do such a thing and a lot of scientific research / mathematical knowledge, not to mention the time, resources, and money needed to successfully do such a thing.,(reply>), Yes even a couple miles up would save a lot of fuel, and a lot of money.<br>Problem is we haven't even built one mile high, wouldn't really know how at the moment.,(reply>), The problem is keeping the structure up right.
