Evacuated tube transport system with improved cooling for superconductive elements

摘要

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 cooperate with the superconductor elements to levitate the capsule.

主权项

1. An evacuated tube transport system having removable magnetic force elements, comprising:
(a) at least one evacuated tube ; (b) a capsule capable of traveling within the evacuated tube, the capsule having a top, a bottom, an inside and an outside, and a circular cross-section; (c) an upper and a lower cryostat respectively removeably mounted on the outside of the capsule; (d) at least a plurality of superconductive magnetic elements enclosed by the upper and lower cryostats; (e) at least a pair of permanent magnetic elements mounted at the top and bottom of the tube, the permanent magnets cooperate with the superconductor magnetic elements to levitate the capsule within the evacuated tube; (f) at least a pair of capsule based switchable diverge force elements at least a pair of tube based diverge force elements to align the capsule within the tube; and (g) the system includes an interchange region with an airlock and a removable mounting element that attaches the upper and lower cryostat to the capsule, the removable mounting element enables removal of the upper and lower cryostat from the capsule in the airlock.
