Abstract
The direct projection of a space vehicle, herein termed a 'Space Train.TM.', into space without combustile fuel is described. A mathematical physics analysis derives critical ranges of parameters, which inlcude a vehicle having a mass of about 3,000,000 Kg., a length of about 180 m and 5 m dia.; an acceleration of about 8 g's during its travel within 1000 km of a vacuum tube parallel to Earth's surface to a velocity of about 12 km/sec., the vehicle exiting from the tube into the atmosphere at an angle of about 3.degree. and an elevation of about 3 km at a maximum deceleration of about 8 g's. An acceleration or deceleration of 8 g's is tolerable to humans in the special chair described herein. The energy imparted to this mass is provided by a conventional electric power source stored as electric energy in superconducting storage inductor rings. The electric energy is discharged to coils around the vacuum tube just in advance of the center of the moving vehicle. A solar electric powered mass thrustor is also described. The Space Train.TM. will decrease the cost of transportation into space by a factor of at least 100; opening the Space Frontier on a cost-efficient, profitable, reliable and safe basis.
