Ex-News JunkieMassaging the numbers a bitSat Dec 2, 2017 11:14am2001:1970:5c25:9400:8d8e:de67:a31b:8c47- (edit) After 10 years of operation, the first space elevator could lift 14,400 cable spools to GEO. Concurrently, the cable spools could be assembled in groups of eight, and each group moved into one of 1800 adjacent GEO positions. The ring would be complete: All GEO orbits occupied by a self-sufficient space elevator installation able to serve all locations worldwide.

- If each installation were to come online immediately every two days (each time a group of eight cable spools are lifted to orbit), then they could also be used to lift additional cable spools and reduce the time to complete the global space elevator ring from 10 years to just 6.5 years.

Global Space Elevator Ring Construction — Ex-News Junkie, Sat Dec 2 3:52amThe Global Space Elevator Ring construction would roughly follow this sequence: - BFR rocket #1 launches to low-earth orbit (LEO) carrying one 250-tonne space elevator cable spool. BFR rocket #2... more

Geometric Growth — Ex-News Junkie, Sat Dec 2 12:11pmIf each space elevator could launch enough cable spools to build an other space elevator every two days, then the number of space elevator installations would double every two days... The time to... more
