Elon Musk is continuing to pursue a new transportation phenomenon-the Hyperloop – essentially a near vacuum tube with a sled inside where the sled can move at high speeds with little friction and drag. A 1,600 foot test track in Nevada has been constructed and a successful test run has been made. Still work to do but the propulsion, braking and levitation system worked well. The video is awesome to watch.
