Cheap, Small Electric Space Propulsion

Authors: Alexander Bolonkin

In this research, the author proposes a fundamentally different way to launch spacecraft. The method is characterized in that the spacecraft is accelerated by an electric accelerator that ionizes the air and throws it at a high speed regardless of the speed of the accelerator itself. The accelerator returns to the launch site after the launch and returns the energy spent on accelerating the accelerator body. That is, the electric ground (from the power plant) energy is spent only on the acceleration of the spacecraft itself. As a result, we have the lowest possible launch cost (about $1 / kg) and are not limited in the number of launches. This will allow us to really engage in space exploration. In addition, in wartime, it allows an unlimited number of military vehicles to launch and organize anti-missile defense (electric gun). The proposed invention also allows to solve the problem of the engine for hypersonic aircraft.
