Hyperloop One performed a seconds long demonstration of the propulsion system that will move the Hyperloop technology along the tracks. You can see the video below.
Hyperloop uses levitating pods over electricity and magnets at more than 700 MPH through tubes. The technology and thought was offered up by Elon Musk to anybody interested. Hyperloop One is a startup hoping to take advantage of that idea. The company hopes to start moving cargo by 2019 and people by 2021.
