With LockHeed Martin drafting plans to construct its own space elevator, it looks like LiftPort may have some serious competition on its hands.
(Google Patents) 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.
Although this differs from LiftPort's version of a space elevator, (which should probably be called a Sky Hook) LockHeed's version would preserve the current rocket industry in its current status.
LiftPort's version, although probably not in the best short term interests of any rocket company, would enable larger cargo to be hauled into space, not to mention giving most countries access to the final frontier.
