Attorney, Agent or FirmInternational ClassB61B 013/00AbstractA ground-based capsule pipeline with greatly improved speed, energy efficiency, and cost for transportation of freight and/or people. Passive magnetic levitation is used to suspend inert, rugged capsules within an air-evacuated pipeline, where they are propelled by a linear motor. Permanent magnet pole arrays incorporated in the capsules interact with inductively-enhanced conductive loops on the interior of the pipeline to produce a low "take-off" speed, high lift, and a high lift-drag ratio.Other References
