Hyperloop One tested

Hyperloop Technologies has changed its name to Hyperloop One and showed off a test of its linear-electric motor on a test track in the desert north of Las Vegas. A 10-foot sled was accelerated to 400 mph along a test track into a pile of sand at a force of 2.5Gs. CTO Brogan BamBrogan hopes to have a quarter-mile track with tubes by the end of the year.
