Harnessing this as a method of power generation however has long proven a challenge.More recently though, scientists at Princeton have been developing a new type of spacecraft propulsion system that takes advantage of the benefits offered by nuclear fusion energy.

Known as the Direct Fusion Drive (DFD), the ambitious engine fuses helium-3 and deuterium to produce large amounts of energy but with next to no dangerous radioactive waste.

While the new drive is still a work-in-progress, its creators believe that it could fly for the first time by 2028 and that it will be capable of significantly reducing the time it takes to reach distant worlds.
