Dear Sir,
If a object is out from a system then it will be not a part of the system. suppose I and you are standing on a roller skating and there is 10 meter distance between us .I stand on the front part and you stands on the end part.Now I’m throwing a ball with the velocity of 5 meter/ second and in reaction the roller skate will move towards front side with you but ball is still in the air (for a moment untill you catch it) and its velocity has reduced from 5 to 3 meter /second .when you will catch it, a back force will be create to pull the roller skating but it will be less than the force was created by me at the timing of throwing the ball towards you. I can collect this ball again from you by using a conveyor belt system.
in this way this engine will work .This engine is not a closed system .the iron ball is expelling outside(having spin velocity) from the inside part of this system and reducing its velocity with itself (using magnetic fluid)and after with reduced velocity is again entering in this system.
if we try this system on the earth then it will work and if this kind system works on the earth then there is no doubt that it will not work in space.
