Cleaner,Greener,Safer,Lighter,Smaller,Quieter,andCooler
GreenTechMotorsCorporation
Every pound of electric motor/generator-related mass reduction substantially reduces propellant mass at each successive propulsive event in an exploration mission.
Reducing energy needs and thermal rejection loads reduces mass of power and thermal rejection systems
Smaller motors package more efficiently, reducing structural mass

MissionDesignandthevalueofEciency:distance,durationandlogistics
! The further the exploration horizon is and the longer the mission, the greater the value of motor/generator efficiency.
! Reliability becomes increasingly valuable for longer duration missions ! Logistical supportability is impractical beyond LEO
