Ramjet

Examiner
A Bussard ramjet is the fastest means of space travel available. Ramjets use the nuclear fusion of hydrogen to accelerate to speeds close to c.

They collect fuel from the interstellar medium, using powerful magnetic fields. These fields are such that safe transportation of living beings was not possible in the early ramjet designs, and lead to the exclusive use of ramjets for unmanned exploration, sending probes to nearby stars.

Only in 28th century was adequate shielding developed, finally allowing the transportation of living beings at speeds up to 0.8c.
