Hyperloop is a futuristic mode of transport that involve pods moving at high speeds in enclosed tubes. These tubes are built with tracks on which the pods move free of air resistance or friction using magnetic levitation technology. Magnetic levitation technology is currently employed in high speed trains with speeds exceeding 400km/hr. Hyperloop technology promises to move humans and goods at even faster speed. High speed rail development have been difficult due to friction and air resistance which increase as the trains approach high speed. The hyperloop concept theoretically eliminates these obstacles by employing magnetic levitation in pods moving at high speeds in vacuum tubes allowing for speeds of thousands of miles per hour. While the hyperloop technology is still been tested in various countries around the world, there are several countries that have began to deploy this new type of transportation infrastructure. Several companies have began testing the hyperloop in the United States, France, India, United Arab Emirates where there has been a limited infrastructure being built and active testing of the technology has been carried out.
The tube is made of steel and maintained at partial vacuum. Inside the tube are tracks similar to rail tracks. The tracks are mounted by a capsule or pod which is used to convey the passenger or goods. The capsule employs magnetic levitation to move through the tracks at high speeds. The capsule is built with a streamlined body to reduce friction and air resistance at it travels at high speeds.
Some companies such as Hyperloop One employ passive magnetic levitation for transportation. Linear induction motors located along the tube would accelerate and decelerate the capsule to the appropriate speed for each section of the tube route. With air resistance greatly reduced and friction all but eliminated the capsules can glide for the bulk of the journey. Most experts still doubt the feasibility of this technology, but nevertheless the enthusiasts who are the proponents of this technology are still pressing ahead with construction of the infrastructure in selected countries. The proposal is that when the first hyperloop infrastructure is completed, it should first be used to transport goods for a period of time, likely years before it will be certified for use to carry humans as a commercial means of transportation.
