Hyperloop is a proposed mode of passenger and freight transportation that would propel a pod-like vehicle through a near-vacuum tube at more than airline speed. The alpha version of the proposal, published on the SpaceX website, describes design claims of the system, as well as its function. The pods would accelerate to cruising speed gradually using a linear electric motor and glide above their track using passive magnetic levitation or air bearings. The tubes could also go above ground on columns or underground, eliminating the dangers of grade crossings. It is hoped that the system will be highly energy-efficient, quiet and autonomous.

The concept of high-speed travel in tubes has been around for decades, but there has been a resurgence in interest in pneumatic tube transportation systems since the concept was reintroduced, using updated technologies, by Elon Musk after 2012, incorporating reduced-pressure tubes in which pressurized capsules ride on an air cushion driven by linear induction moto
