Hyperloop One, previously known as Hyperloop Technologies, is a company in Los Angeles, California, that is leading the effort to commercialize the Hyperloop for moving passengers and/or cargo at airline speeds at a fraction of the cost of air travel. The concept of Hyperloop transportation was introduced and named by Elon Musk in August 2013, although he is not involved with Hyperloop One. The Hyperloop uses a linear electric motor to accelerate and decelerate an electromagnetically levitated pod through a low-pressure tube. The vehicle will glide silently for miles at speeds of up to 1,000 km/h (620 mph) with no turbulence. The system is designed to be entirely autonomous, quiet and on-demand (departures every 10–20 seconds) and, as it is built on columns or tunneled underground, eliminates the dangers of at-grade crossings and requires much smaller rights of way than high-speed rail or a highway. Hyperloop One has made substantive technical changes to Musks initial proposal and chose not to pursue the San Francisco-to-Los Angeles route that Musk envisioned in his 2013 white paper. The company has raised $160 million and successfully demonstrated its propulsion technology in May 2016 at its test site north of Las Vegas and is currently building DevLoop, its full-system test track. Hyperloop One expects to achieve "first flight" of the complete system (with levitation, propulsion, pod vehicle, control systems and low-pressure tube) early in 2017. Hyperloop One is developing passenger and cargo system routes in the United States, Finland, the United Arab Emirates, Russia and Switzerland. Its publicly stated goal is to deliver a fully operational Hyperloop system by 2020.
