That's not something we're likely to see in our lifetime, however we may witness the completion of several "Hyperloop" transport systems designed to get you from point A to point B at breakneck speeds. This is the dream of Tesla founder and CEO Elon Musk, who describes Hyperloop as a "cross between a Concorde, a rail gun, and an air hockey table." Alternately, you can think of it as an enclosed tube that's propped way up off the ground. It would use a magnetic levitation system similar to high-speed bullet trains, except passengers would travel in capsules across a surface with almost no friction. A Colorado company called ET3 (Evacuated Tube Transport) is already working on making Musk's dream a reality by building a similar system and is planning a 3-mile trial run before the end of the year. This is just the beginning of bigger and faster things to come, According to ET3, a six-passenger capsule about the size of an automobile could hit speeds of 4,000 miles per hour on longer distances, such as going across the country or even continents.
