Now, a group of Japanese scientists are convinced that they can build a space elevator more quickly and cheaply than has been believed possible.
Such a cable could convey cargo into space very cheaply and easily. Carriages would travel up and down the cable under modest power, not the vast expenditures of energy that are currently needed to send anything into orbit.
