Hyperloop - the thrilling details (and some satire!)

Hyperloop is a hypothetical mode of high-speed transportation proposed by entrepreneur and SpaceX founder Elon Musk. Musk has envisioned the system as a 'fifth mode' of transportation, an alternative to boats, planes, automobiles and trains. The system would, according to Musk, be able to travel from downtown Los Angeles to downtown San Francisco in under 30 minutes or 343 miles (552 km) at an average speed of more than 685 mph (1,102 km/h)
