A High Temperature Superconductor Maglev (HTSM) for Evacuated Tube Transport (ETT) with a magnetic levitation structure for ETT capsule vehicles traveling in an evacuated tube. At least one ETT capsule travels within an evacuated tube, an upper and a lower cryostat respectively mount at the top and bottom of said ETT capsule along the length thereof, at least a plurality of superconductor levitation force elements divided between said upper and lower cryostats. The levitation force being spread over the length of capsule, however substantially concentrated in a compact cross-sectional area. At least a pair of permanent magnetic elements mounted at the top and bottom of the evacuated tube to levitate the capsule. At least a pair of capsule based switchable diverge force elements cooperate with at least a pair of tube based diverge force elements to steer the capsule while in an interchange.

1. A system for Evacuated Tube Transport with a magnetic levitation structure for enabling capsule travel in an evacuated tube, comprising: (a) at least one evacuated tube;(b) at least one capsule having a surface, a length, a top and a bottom, and being capable of traveling within said evacuated tube;(c) an upper and a lower cryostat respectively mounted by a removable mounting element at the top and bottom of said capsule, each cryostat being designed to house superconductive levitation force elements, each removable mounting element being magnetic to enable rapid removal of the cryostats from the at least one capsule;(d) a plurality of superconductor levitation force elements in said upper and lower cryostats, said levitation force elements being spread along the length of the at least one capsule;(e) at least a pair of permanent magnetic elements mounted at the top and bottom of said evacuated tube to levitate the capsule within said tube, said permanent magnetic elements being separated by non-conductive spacers;(f) at least a pair of capsule based switchable diverge force elements; and(g) at least a pair of tube based diverge force elements. 2. A system as set forth in claim 1 wherein the tube includes an interchange with an airlock for loading and unloading the capsule, the cryostat is mounted internally on said capsule to pass through a cylindrical airlock with minimal time and energy. 3. A system as set forth in claim 1 wherein the cryostat is mounted externally on the last one capsule to prevent leakage of material and to make more space available inside the at least one capsule. 4. A system as set forth in claim 1, wherein said cryostat is made of an electrically non-conductive material and configured in a cylindrical shape. 5. A system as set forth in claim 1, wherein said cryostat is mounted on said capsule by means of insular mounting elements. 6. A system for Evacuated Tube Transport with a magnetic levitation structure for capsules traveling in an evacuated tube, comprising: (a) at least one evacuated tube having an interchange;(b) at least one capsule having a length, a top and a bottom and being capable of traveling within said evacuated tube;(c) an upper and a lower cryostat respectively mounted on the capsule by means of a removable mounting element, magnetically mounted at the top and bottom of said capsule;(d) at least a plurality of superconductor levitation force elements divided between said upper and lower cryostats, said levitation force being spread over at least some of the length of capsule;(e) at least a pair of permanent magnetic elements mounted at the top and bottom of said evacuated tube to stably levitate the capsule within said tube;(f) at least a pair of capsule based switchable diverge force elements having selectively polarized magnetic force means, said magnetic force means are oriented on the capsule to magnetically interact with electromagnetic material in corresponding areas in the tube to supply ample steering force to cause the capsule to diverge at the interchange,(g) at least a pair of tube based diverge force elements that cooperate with the capsule based switchable diverge force elements to enable the capsule to diverge at the interchange. 7. A system as set forth in claim 6, wherein the interchange has an airlock for loading and unloading the capsule, the cryostat is mounted externally on said capsule enable rapid replacement of the cryostat when the capsule is in the interchange. 8. A system as set forth in claim 7, wherein the cryostat is replaced in the interchange when the interchange is in an evacuated condition. 9. A system as set forth in claim 6, wherein said cryostat is made of an electrically non-conductive material and configured in a cylindrical shape to house said superconductor elements. 10. A system as set forth in claim 6, wherein said cryostats are mounted on said capsule by means of insular mounting elements without providing a heat path between said cryostats to said capsule. 11. A system as set forth in claim 7, wherein the airlock is filled with air at standard temperature and pressure after the cryostat is removed to enable loading and unloading of cargo. 12. A system as set forth in claim 7, wherein the airlock is at least partially evacuated prior to replacement of the cryostat. 13. A system as set forth in claim 12, wherein the airlock is fully evacuated prior to replacement of the cryostat. 14. A system as set forth in claim 12, wherein the system includes two tubes mounted in vertical alignment with each other on columns. 15. A system as set forth in claim 12, wherein the permanent magnets are separated by a spacer made from a dielectric material.
