Absent an acceleration such as due to gravity or rotation, there isn't anything to induce differential movement between the denser and less dense materials in the first place. Once there is an acceleration, then the greater density material is subject to a greater force, and the system will naturally seek to redistribute mass going from any starting state towards the PE minimum state.

Where the starting state is not the PE minimum state, energy can be extracted during such a traverse. After such a traverse the PE difference between states has been lost and must be replaced to return the system to its original condition.

MarkE,

Actually at that distance from the earth of an orbiting space shuttle, the gravitational force is still 90-95%. They're in a free-fall weightless environment and not free from the gravitational force. This satisfies the conditions as stated by AC, which is being in outer space where we have mass but no weight. Besides, you're still inverting the effect for the cause....and inverting the direction of the force for the prime mover.

The buoyant force on a submerged object is the result of the gravitational pull on the surrounding fluid be that fluid: air, water, helium, hydrogen disulfide, or whatever counteracting the gravitational pull on the submerged object. When the surrounding fluid density is greater than the submerged object density the net force is up. It then takes work to displace more dense surrounding fluid up in order to submerge / further submerge the less dense object. The surrounding fluid is indeed pushing the submerged object up.

This is another inversion of the truth. In this case, the greater force is the atmospheric pressure and not the gravitational force. How convenient of you to leave out the atmospheric pressure. This is similar to there being a greater force as we found in the blowing your own sail example.

Watch the video again. When he lifts the tube out of the water, the atmospheric pressure forces air into the tube. The atmospheric pressure wouldn't be able to fill the tube with air if the gravitational force on the water is greater. The water then begins to fall out of the tube at the rate the tube is being filled with air by the atmospheric pressure. If the gravitational force on the water is the greater force, then we wouldn't see the tube filling up with air, and all of the water would fall out of the tube at nearly the same time at the acceleration rate of gravity (it would be like turning a full glass of water with no lid upside down). You have inverted the effect for the cause, and you have inverted the direction of the force for the prime mover.

Atmospheric pressure is gravity-so put that in yer pipe and smoke it!!!

Like I said, this is similar to there being a greater force as we found in the blowing your own sail example. And, why can't the atmospheric pressure be anti-gravity also under the right conditions? The pressure at the bottom of the tube has a greater force pointing up than the pressure at the top of the tube that is pointing down. Call it whatever you like, but it doesn't change what it is, which is a pressure differential. You just have to get the direction of the greater force right. Put that in your pipe and smoke it!!! Oh, and don't drink the bong water, LOL.
