Coilgun

A coilgun is a type of electromagnetic launcher that uses a series of coils to accelerate a projectile. When an electric current flows through the coils, a magnetic field is created that propels the projectile forward. Coilguns have the potential to achieve very high velocities and are being researched for use in a variety of applications, including space launch systems and spacecraft propulsion. One of the main advantages of coilguns is that they do not require any propellant, which makes them more efficient and less expensive than traditional rocket engines. However, they also have some significant challenges, such as the need for high-power electrical systems and the potential for electromagnetic interference with other spacecraft systems.
