Hyperloop transport. Illustration of a planned high-speed transportation system known as the Hyperloop. Passengers are transported in pressurised capsules that ride on a cushion of air in tubes with reduced air pressure. It is thought that speeds of up to 1220 kilometres per hour could be attained. The initial design, by entrepreneur Elon Musk, was announced in August 2013 and is intended to run from Los Angeles to San Francisco in California, USA.
