One of the most significant potential applications of KESTS to GEO would be to provide the transportation between ground and large scale space habitats in GEO. Real estate. It is conceivable that in the future, maybe even uncomfortably near future, civilization will need to lift much of its load from the earth surface environment. High technology civilization may need to move to space, possibly just as normal expansion, possibly as an emergency measure if the earth surface ecosystem goes into cascade failure mode. For this reason, it would be wise to look into the possibility of rings of space settlements infilling GEO, built primarily from lunar and possibly asteroidal material resources, in robotic subassembly mass production. Final assembly and furnishings would be done by people.

The potential instability of a solid orbiting ring would occur when slow orbital frictional forces slow the ring's velocity, requiring it to go to a lower orbit, but being of size only for the higher orbit, eventually collapsing. Being semisolidly attached to the KESTS, the KESTS would need to continuously deliver the kinetic energy to the ring so as to maintain its velocity, stay in place and therefore the orbiting ring would not collapse.

Maglev rail systems will need to link the space settlements together, as well as link them all to the KESTS upper terminal. Alternate rotation direction of the Stanfor Torus type space settlements would help re the gyroscopic precession of them if they are stacked concentrically, with the interlinking maglev rail going through their centers; this will require each space settlement to be forcibly by rotated once each 24 hours, probably via bearing pressure to each neighbor. If the configuration of the ring is so that they all free rotate, then a maglev link would need to be done outside the path of their 24 hour swing relative to the earth surface.
