Billionaire investor Elon Musk has unveiled plans for a “Hyperloop” transport system he hopes will one day shuttle passengers and cars between Los Angeles and San Francisco travelling faster than the speed of sound.
After almost a year of speculation Musk outlined his plans for the system Monday in a blog post and a 57-page PDF . People and cars would be transported between cities inside aluminum pods traveling a speed of up to 800 miles per hour inside elevated tubes. In a conference call Musk said he had been inspired by the pneumatic tubes used for transporting mail around some buildings.
The PayPal founder has long been obsessed with transport and used his fortune to develop electric-car firm Tesla and the private spaceflight company SpaceX. Musk has previously said that Hyperloop will be a “cross between a Concorde and a railgun and an air hockey table.”
