StarTram: a rocket to the magnetic levitation deliver cargo into space

Missiles are not the most efficient way to deliver goods and people into space, because they consume too much fuel: about 800 kg of fuel per 1 kg of its weight and cargo. Missiles, we use only for the simple reason that the elevator is still in orbit was not built. In addition to the elevator company proposes to build a missile StarTram, which moves through a magnetic levitation.

To lift into orbit, engineers StarTram offer to build a huge magnetic tunnel whose length is about 130 km, on the tunnel rocket or some other means of transport will rise into orbit. Inside the tunnel is supported by the vacuum state, through which at minimum cost will be to break up this space ship to the insane speed of 32,000 sq km / h Out on arrival through a plasma screen at the top of the rocket. Space Shuttle Payload StarTram up to 35 tons.


According to the project, the construction of such buildings should take at least ten years and will cost $ 20 billion reckless. However, this amount will be repaid with interest, because each round of the orbit will cost just $ 20, it is in the hundreds, even thousands of times cheaper than now. Another important point is that it will only load the vehicle, because it feels the motion of the acceleration in 30g, so people will not stand overload.

In theory you could build a rocket and passenger magnitolevitiruyuschuyu StarTram, which will provide an overload in a reasonable 2-3g. That's just the length of the passenger tunnel would be about 1500 km, and it must end at an altitude of 225 km, otherwise people will die at the exit of the capsule. A motion for a magnetic levitation will need a power supply with a current of 280 mA (megaamperov) plus the current 14 mA, which goes in the opposite direction on the surface of the tunnel. If you add up the cost of construction, electric power plant and the levitating capsule, will amount to $ 67 billion if anyone will agree to invest in this project? Time will tell.
