Was the Hyperloop made to stop high-speed rail?

Musk reportedly told his biographer, Ashlee Vance, that the Hyperloop proposal was motivated by “his hatred for California's proposed high-speed rail system,” which he felt would be too slow, outdated and expensive. “With any luck, the high-speed rail would be canceled,” Vance wrote.

The Hyperloop system is expected to be a faster and economical alternative to conventional short- range aviation and high-speed rails. Moreover, a market study by NASA (Taylor et al., 2016) concluded that developing Hyperloop facilities would be cheaper than other high-speed railway Page 5 5 networks.

First imagined at least 100 years ago, it would basically look like some version of those green tubes on Futurama. Imaginary no longer, it would seem. If everything goes according to plan, Hyperloop One's pods will carry humans and cargo at 760 mph — 30 percent faster than a 747 airplane.

If you have 10 tons per square metre pushing on the outside of the Hyperloop, and nothing pushing on the inside, there is a risk of a vacuum collapse - essentially the tube being crushed by the atmosphere, says Mason.

There is no Hyperloop service in the U.S. today. First mentioned by Musk to a reporter in 2012, the Hyperloop is a high-speed electric vehicle that carries passengers and travels in a low-pressure environment such as a vacuum tube without touching the walls.

China is likely to build its first hyperloop train line between Shanghai and Hangzhou, according to the nation's top engineering and rail design institutes. The 150km-long (93-mile) in-vacuum tunnel will allow maglev trains to travel at speeds of up to 1,000km/h (621mph).

Safety and Comfort The design proposed by Musk (2013) indicates hyperloop will be safer compared to other rival transport modes, such as airplanes and trains.

All it takes is one leaky seal or a small crack somewhere in the hundreds of miles of tube and the whole system stops working, Musk wrote in his initial Hyperloop report. Another technical problem centers on the pod moving through a tube containing air.

The proposed accelerations for the Hyperloop are a factor of seven greater than the Shinkansen in Japan allow for concerning human passengers, as humans can only handle about 0.2g's (or about 2 m/s^2) of acceleration in the up-and-down or side-to-side directions.
