This won't enable perpetual space travel in case anyone thought so.
Rockets need to eject particles to generate force.
And to eject 1 kg of fuel, its photo synthesis system has to lose 1 km of mass in one way or another.
The solution is to find a way to generate thrust without rocket fuel ejection.
