B Would the following test be proof of a successful propulsion system?

[Fizzics]

If an apparatus was placed in a sealed box, and was then fixed to the seat of a childrens swing or a pendulum.

And then, if it could propel itself (total mass 10kg) forward approximately 5 inches with a single pulse independently of any outside assistance and also without repositioning any masses within the box.

This pulse could then be repeated an unlimited amount of times, also there would be no external influences such as a fan or wind.

Would this apparatus then be proof of a successful propulsion system that could be used in outer space?

No.
It might move a swing, but that says nothing about space travel, where there is no rope or tensile force. The swing, and the tree that supports it, rotates with the Earth on its axis.

How would the energy required for a propulsion system enter the sealed box?

This appears to be an attempt to discuss Reactionless Drives. They are a Forbidden Topic per the PF Rules. The thread will remain closed.
