Stability of the space cable

A key issue with these dynamically supported structures is lateral stability, particularly in the presence of varying cross winds in the stratosphere. The relevant partial differential equations are derived below with a set of solutions. A proposal is presented for providing stability by means of tethers, pipes, and a support structure at each end. Each support is a miniature space cable rising to 15 km, and it bears the load of the tethers and pipes that would otherwise have to be carried by the main structure.
