Abstract : A suggestion for using Jules Verne's well-known idea for using a cannon to send a spacecraft to the moon for launching very heavy payloads into space is offered. The author proposes an electric cannon consisting of a 500-km-long solenoid for shooting needle-shaped, 1000-ton cargo capsules into space. The capsule would be inserted into an airtight vacuum tube of the solenoid, and magnetic cushions would protect the capsule from rubbing against the walls. The acceleration of the capsule inside the solenoid is produced by the automatic sequence switching coils located along the tube. At an acceleration rate of 8 g, the capsule would attain a velocity of 8 km/sec in about 100 sec, requiring about 320 kw of power per kg of its weight. In this way a 1000-ton capsule would require 320-million kw of peak output, or twice the amount currently produced by all Soviet power plants. However, if this electric cannon were to launch 20 such capsules per day, its average power requirement would be only about 7 million kw, which could be met by a large hydroelectric power plant. Certainly, a project of such magnitude would necessarily encounter numerous problems and obstables. The figures show, however, that a facility with a power of several million kw could launch 20,000 tons of payload into space per day.
