Colonizing space will require a lot of stuff, iron to build space stations, titanium to build spaceships, oxygen for us to breathe, and many other resources. Lifting all this up from the surface of the earth on rockets is simply not feasible. Thus, we will need to find these resources somewhere else. You need look no further than the moon. It has all the natural resources we need to colonize space but the question remains, how do we get them into orbit? Even on the moon, rockets are not feasible, but something else might be.
An idea emerged over a century ago called a mass driver. The first mass driver described in print was in the 1897 science fiction novel A Trip to Venus by John Munro. He called it an electric gun. It was his imaginative method of launching vehicles into outer space from the Earth’s surface. Munro describes the electric gun as a series of coils energized in a timed sequence to provide the force necessary to get the spaceship into orbit.
