Communications and Science
It is possible to place an astronomical observatory on it to get
capabilities like the Hubble telescope but with easy access for
A large version can launch a manned spacecraft directly to orbit.
Smaller versions can replace a first-stage rocket. Combined with an
electric gun, it can launch unmanned
craft into interplanetary space.
Magnetic levitation and linear induction motors are already in use in
trains. The popular material Kevlar is strong enough for structural
Theoretical calculations show that the structure can be made stable in
strong winds. This needs to be tested. There is built-in fail-safe
redundancy, but there are still questions about safety.
and the Environment
It can generate large amounts of electric power by holding solar panels
above the clouds. It can boost ramjets or scramjets. A small version is
suitable for rescue from tall
