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. |

Claims1. A space elevator for transporting a payload from one point to another in outer space, comprising: - a first structural means, located at a first substantially fixed orbital distance from the surface of the earth, for receiving payloads,
- a second structural means, located at a second substantially fixed orbital distance from the surface of the earth, for receiving payloads, said second distance being greater than said fist distance, no portion of said elevator is attached to the earth's surface, and
- payload-transporting means disposed between and interconnecting said first and said second structural means, said payload-transporting means includes cable means extending between said first and said second structural means, said cable means comprising lifting cables and load cables, wherein said lifting cables comprise a lower strength, less dense, material than said load cables, and a housing supported by said cable means for traveling along said cable means, said housing being capable of moving said payload between said first and said second structural means, said housing further includes a drive motor for propelling said housing along said lifting cables.
2. The space elevator of claim 1, wherein said lifting cables comprise interwoven bundles of fibers, said fibers being bound together at spaced locations. 3. The space elevator of claim 2, further comprising cable connector cross-beams connected between said load cables and said lifting cables. 4. The space elevator of claim 3, wherein successive sections of said lifting and load cables are attached to said cable connector cross-beams. 5. The space elevator of claim 2, said spaced locations being approximately every 25 meters. 6. The space elevator of claim 1, and further including an apex station disposed between said first and said second structural means and positioned at a center of gravity of the space elevator. 7. The space elevator of claim 6, further including engine means positioned at the apex station for maintaining said first and said second structural means substantially fixed within an orbit at said first and second distances from the surface of the earth. 8. The space elevator of claim 1, wherein said first and second structural means each comprise docking means for space craft, and means for transferring payloads between said space craft and the respective structural means at which it is docked. 9. The space elevator of claim 1, further comprising: - means for friction coupling the drive motor to the lifting cables.
10. The space elevator of claim 9, wherein the means for friction coupling the drive motor to the lifting cables comprises: - wheels in contact with a surface of at least one of the lifting cables.
