So here's an interesting patent found by the Robot Guy concerning a patent Lockheed Martin holds for a version of a space elevator.
Abstract:
"A Space Elevator for transporting a payload from one point to another in outer space, includes a first structure, located at a first relatively fixed, non-zero orbital distance from the surface of the earth, for receiving payloads, a second structure, located at a second relatively fixed orbital distance from the surface of the earth, for receiving payloads, where the second distance is greater than the first distance, a third structure located near the center of gravity of the combined apparatus providing a platform for storing and/or processing payloads, and a payload transporting apparatus disposed between and interconnecting the first and third and second and third structural means."
This is very interesting!
I would not be surprised if this version of SE received more funding than LiftPort's because it would drop the cost of space travel all the while preserving the rocket industry.
Unfortunately it would not allow most countries to access space (not to mention certain disabled persons) and if a ground one was ever built, it may put this one out of business.
