Spaceship - Bussard Ramjet

A theoretical spaceship imagined in the 60s by Dr Bussard, this spaceship would travel the interstellar void by capturing the sporadic hydrogen atoms through a miles-wide electromagnetic net, then compress them enough to achieve fusion reaction, thus sustaining power and gaining thrust without carrying fuel.
