One of the inventors maglev (magnetic levitation train), is widely used in China now, he proposed a draft cosmic train. According to James Powell, a train lets you send into space four million people a year. First Startram may appear in 20 years. Under the proposed concept, the train will "shoot" into orbit from the pipe, the length of which is about 130 km. At the heart of Startram will put existing technology of magnetic levitation. According to the author of the project, the cost of launching one kilogram of cargo into orbit will be less than $ 40. With powerful electromagnets with a cargo capsule will fly out of the pipe at a speed of 8 km / sek.
The cost of creating a cargo version Startram, according to estimates by James Powell, 20 billion. Dollars, the passenger - 60 billion. Dollars. See also:
