Envisioned structures

Name	Height	Year of proposal	Type	Main Use	Country	Place	Description	Floors
The Space Elevator	100,000 km (62,137 mi)	1895	Massive space tether	Space tourism, space exploration, and space colonization	UAE[2][3]  Japan[4]  China[5]  Russia[6]  USA[7]	Pacific Ocean[a]	An extraordinarily long cable, anchored on or near the equator, held up by the rotation of the Earth.	N/A
The Orbital Ring	160 km (99 mi) to 80 km (50 mi) of minimal height	1982	Suspended ring structure around Earth	Space tourism/exploration/colonization, space manufacturing, telecommunication, and space-based solar power[8]	undetermined	undetermined	The orbital ring is a concept of an artificial ring shaped cable placed around Earth and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity.[9][10][11] A motorized platform is placed on the cable that runs in the opposite direction to the rotation of the ring at a speed that makes the platform become stationary relative to the ground. The advantage of this concept is its much lower altitude compared to a space elevator which has to maintain its center of mass around geostationary orbit. Multiple tethers can be connected from an orbital ring to the ground enabling mass-transport to space.[8]	N/A
