The seven billion people of the Clarke Belt Cities are desperately seeking ways to return to their homes on the ground, after being stranded in Geostationary Earth Orbit by the cutting down of their centrifugally-supported space escalator by which they had temporarily migrated to cities built up there, to live in while the Earth's ecosystem was being cleansed and jump-started back to a long-term viable condition again. Now, how can they get back down? "It's Down To Earth" is a science fiction novel in a series by Jim Cline about efforts to rejuvenate the planet by gaining high efficiency electrical lift access to high earth orbital space resources of constant solar energy, total recycling of toxic materials, high level rocket launch facilities, and plenty of room to live; all made possible by building various space access hoop structures electro-dynamically supported by kinetic energy stored circulating within themselves.
