Robert W. Bussard (engineer)

Robert W. Bussard was an American physicist and engineer best known for conceptualizing the Bussard ramjet, a theoretical spacecraft propulsion system. This idea involves using a magnetic field to collect and compress hydrogen from space, fueling a nuclear fusion reactor onboard to generate thrust. The goal was to enable long-distance space travel without carrying fuel. Although practical implementation remains challenging and unproven, Bussard’s concept has influenced research in advanced propulsion and fusion energy, highlighting innovative ways to explore interstellar travel and energy harnessing.
