Ion thrusters achieve high fuel efficiency despite producing very low thrust
Ion thrusters and related electric propulsion systems achieve exceptionally high fuel efficiency (measured by specific impulse) while operating at relatively low overall thrust levels.
The retrieved papers consistently confirm that electric propulsion technologies like ion and plasma thrusters achieve high specific impulse and fuel efficiency while producing low absolute thrust compared to chemical rockets.
