Would the release of a dump in a space station provide Velocity?

Answer 1

You have, no doubt, hit on a break through in propulsion.

You could eat and dump your way across the universe and there's no better time to start than now.

Answer 2

Yes it does. Most spacecraft vent some amount of gasses or liquids at different times. They are usually equipped with "Non-propulsive" vents that are typically "T" shaped. The idea is for an escaping gas to spray in two streams at exactly 180 degrees apart so that no forces are imparted to the vehicle.

However, in actual practice most of these vents do not work very well. Even on vehicles the size of the ISS and Space Shuttle (each over 200,000 pounds), venting cabin air or water overboard will affect the vehicle. Typically the effect is more the attitude control system (ie which way are we pointing?) rather than the actual orbital velocity. But in short YES there is an effect to both the attitude and the velocity even when venting systems are designed to prevent it.

Answer 3

Yes, it would provide some velocity. But, if you would keep the dump in and just use the flatulence caused by it, you would have more velocity. You lose energy in the transference of the dump from the inside to the outside. Keep it in and just fart all the time. You'll go much farther.

Good luck with that.

Answer 4

Yes, equal and opposite reaction. You know the conservation of momentum.

Answer 5

Yes.
Beer and cabbage could help a lot! LOL
