In 2013, the concept was published by entrepreneur Elon Musk in a white paper, where the hyperloop was described as a transportation system using capsules supported by an air-bearing surface within a low-pressure tube. [2][3] Hyperloop systems have three essential elements: tubes, pods, and terminals.
Hyperloop is essentially a magnetic levitation (maglev) train system that uses one set of magnets to repel cars so that they hover above a track and another set of magnets to propel them forward over the track.
