Momentum conversion drive possible ?

[Johno]

Hello!

Would it be possible to brake a magnet by means of short circuiting a coil placed at the end of a plastic tube where the magnet has been accelerated in ? Is there a conversion of magnet speed to electric current/energy inside the braking coil ? It is thaught for reusing the projectile that is used for propelling forward by means of fireing it rearward.

No. Reactionless drives violate conservation of momentum.

You can brake a magnet again, perfectly cancelling whatever propulsion you might have gained from it before. That's a very elaborate scheme to heat the environment with no other effect. What is the goal?

The goal is a propulsion system by means of throwing away a magnet weight and capturing this magnet weight agin after braking it hopefully without braking the whole wessel. ... maybe the coil energy could be recuperated and would not be lost.

Sorry, can’t be done. You can’t get around conservation of momentum here. No matter how cleverly you arrange your coils and electric currents, you will always find that you end up braking the entire vessel so you don’t get any propulsion.

The forum rules do not allow discussion of reactionless drives, so this thread is closed.
