The Hyperloop is a concept of high-speed transportation system designed by entrepreneur Elon Musk. The most interesting of Musk's statements is that the Hyperloop is a cross between the Concorde, a railgun, and an air hockey table. It incorporates capsules which ride on an air cushion that is driven by linear induction motors and air compressors. Riding on a cushion of air would enable super-fast speeds.
The transportation system is expected to achieve a top speed of 760 mph. The conceptual route runs from San Los Angeles region to the San Francisco Bay Area.
The properties of friction and air resistance have impeded us from developing high speed transport. The Hyperloop eliminates these obstacles by levitating the train magnetically, allowing to reach theoretical speeds of thousands of miles per hour. However, drawbacks of the system include high cost of maglev and the difficulty in maintaining vacuum over a very long distance.
