SUMMARY

The discussion centers on the feasibility of creating unidirectional movement by applying force to a closed cylinder containing gas or a solid ball, akin to the EmDrive concept. Participants concluded that while the idea may seem plausible, it ultimately violates the principles of momentum conservation, as any force applied to one side results in an equal and opposite reaction. The EmDrive, which purportedly utilizes electromagnetic radiation for propulsion, has been deemed ineffective, requiring increasingly more energy to counteract momentum, thus making perpetual motion impossible.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concept of momentum conservation
  • Basic knowledge of propulsion systems, specifically the EmDrive
  • Awareness of thermodynamics related to energy and heat transfer
NEXT STEPS
  • Research the principles of Newton's laws of motion in detail
  • Explore the mechanics of momentum conservation in closed systems
  • Investigate the scientific critiques of the EmDrive and its theoretical underpinnings
  • Study thermodynamic principles related to energy efficiency in propulsion systems
USEFUL FOR

Physicists, aerospace engineers, and students interested in propulsion technology and the fundamental laws of motion will benefit from this discussion.

TL;DR
Produce thrust in a closed chamber when the opposite momentum is compensated with more energy?
This is in fact a shamelessly simple question to a point the reason it puzzles me is because it's too simple:

So basically you have a closed empty/hollow cylinder filled with either gas or even an ordinary solid ball...and then on the left side of the cylinder you put a force on the "fuel" (gas/ball...) so that it moves to the other side and hits it producing movement. Now, since the ball will come back once it hits the right side then can you produce movement ONLY in one direction for as long as you increase the energy from the left side that pushes the ball?

In fact this idea is very similar to the "emdrive" concept:

Yet I am not sure if the "emdrive" design realizes they will need more and more energy to battle the bouncing wave so perpetuum mobile is impossible?

And if this is possible at tall then you may say it's useless since you need more and more energy to combat momentum yet notice how if you have strong amount of heat but limited amount of fuel this is very useful. For example: you can use million degrees hot nuclear reaction in a rocket but you cannot find fuel in the cosmos to recharge the rocket...well it's not easy...thank you!

You can do anything you want if you have a sufficient supply of ""s.

Other than that, from what I can parse, you might consider that "putting a force" on the inside component to make it go to the right will cause the outside component to go to the left. No matter what you do, the centre-of-mass stays in the same place.

(If I remember, correctly) the Em drive is supposed to use some abstract group property of EMR ; the illustration you've linked to simply shows a fancier version of what you've got... which doesn't work.
