Recover energy from temperature

    I would like to know if it's possibl to recover energy from temperature with this system ? I imagine e very thin so I don't need to give a lot of energy in the system. The efficiency seems to be at 0.5. X forces compress volume and Y forces too in the same time. Y forces allow to move lower distance.

    I think the energy needed is not SeP but it's ( (S1-S)e+(S2-S1)e1+(S3-S2)e2+(S4-S3)e3+(S5-S4)e4 )* P, even Surface is the same, thickness decrease more and more.

    Red surfaces move with lower linear velocity to the right, so this need less force force compressed all volumes.

    Energy won for each volume is :

    PSe - PS(mean e') = PS(e-mean(e'))

    Gas is compress/depress with adiabatic process.

    If I use valves for red surfaces, the work I need to give is PdV, dV is the same but P is 0.45 bar not 1 bar. So where I lost energy ?
