SANDAEROVATOR
Sandaerovator is an aerospace buoyancy/electromagnetic launch/building elevator and base structure/connection for ocean/terrestrial/aero/space cities. Sandaerovator structure has horizontal wing wind stabilizers, formed by modules with independent counter wind and flying buoyancy/propeller/rocket propulsion. Sandaerovator can be used as an exterior elevator for any current, new or expanded building, and as an electromagnetic accelerator launching platform for a Sandaeroship, Sandaerocopter and/or Sandaerocket, including via a cable or vacuum tube coil gun. Sandaerovator can be connected and give access to SANDAEROCITIES, atmospheric Acities or geostationary Space Cities (Sandaerospace Scities), including a non-fixed connection to a Lunar City. Sandaerovator can gradually combine space elevator, tower, hook, rotor, loop, ring concepts using wing aerodynamics, flying wheel, wind propellers, gas/vacuum buoyancy, centrifugal gravity, accelerated vapor/water pressure, electromagnetic/kinetic energy, in double counter loop, for active support structure, pushing structure up, reducing gravity compression. Multi orbit Sandaerospaces can have velocity synchronized with upward tensile or propulsive counter force to allow straight elevation until geostationary orbit.
