Bussard Ramjet

"The Bussard ramjet method of spacecraft propulsion was proposed in 1960 by the physicist Robert W. Bussard and popularized by Carl Sagan in the television series and subsequent book Cosmos as a variant of a fusion rocket capable of fast interstellar spaceflight. It would use a large scoop (on the order of miles in diameter) to compress hydrogen from the interstellar medium and fuse it. This mass would then form the exhaust of a rocket to accelerate the ramjet. A workable ramjet design could in principle accelerate indefinitely until its mechanism failed. Such a ramjet could theoretically accelerate arbitrarily close to the velocity of light, and would be a very effective interstellar spacecraft. How long it will take a ramjet driven starship to obtain a given fraction of the velocity of light is determined by the thrust to mass ratio of the interstellar ramjet."
