Recover energy from pressure

Hi, Why it's not possible to recover energy from pressure with this method ? Shape 1 has gas (or liquid) with pressure at 1 bar. All volumes are contant. Outside there is 0.1 bar. I drawn 2 cut views of the system. Shape 1 move down on the cut side view, shape 1 has only 4 walls when it is complety between 2 solids, it's…

Hi,

Why it's not possible to recover energy from pressure with this method ?

Shape 1 has gas (or liquid) with pressure at 1 bar. All volumes are contant. Outside there is 0.1 bar. I drawn 2 cut views of the system. Shape 1 move down on the cut side view, shape 1 has only 4 walls when it is complety between 2 solids, it's SOLID 1 and 2 that assumed 2 others walls with gaskets. In the image shape 1 has 6 walls, but 2 walls (slopes) are assumed in part with SOLID 1 and 2. Physics says it's PdV that give energy, so I think it's not possible because all volumes are constant, but I don't understand why not. Could you explain ?
