Bussard Ramjet

A Bussard Ramjet is a theoretical spacecraft design that collects hydrogen from space using a large magnetic field and then uses this fuel for nuclear fusion to generate thrust. It essentially acts like a scoop that gathers interstellar particles, which are then fused to produce energy for propulsion. This concept allows a spacecraft to travel through the galaxy without needing to carry vast amounts of fuel, making long-distance space travel more feasible. While promising in theory, it faces significant technical challenges, such as efficient collection and fusion of sparse interstellar hydrogen.
