Elon Musk’s Hyperloop concept involves sleek passenger capsules flying within a tube on a cushion of air. Solar panels along the entire length of the tube provide more power than needed to run the system. Capsules travel just under the speed of sound, at 760 mph (1,220 km/h). Passengers could travel from San Francisco to Los Angeles in 35 minutes.
Streamlined capsules carrying 28 passengers each would depart from the station every few minutes. Passengers ride in pairs, with luggage stored at the front or rear of the capsule. The system is designed to keep accelerations on the passengers below 0.5 g (one-half the acceleration of Earth’s gravity).
