Recover energy from temperature

[rc4]

The thickness of worm drive thread is equal to thickness of gear. When I turn one turn I move up a tooth to one pitch, but the thickness of thread increase the distance. I move to 2 teeth. A gear give PV for tooth/notooth (a pitch), so here the sum of energy is 0, but if thickness of thread is near 0, in one turn of worm drive I move up one tooth, the next turn too, but gear give/recover energy only for one tooth, after it's a blank.

P = 100 000 Pa

Ok 100 000 Pa, but if the volume is too litle 0.000001 m³ or lesser it will be almost nothing. How many anions or cations are produced with this?

Another idea:

All under pressure P.

Roll up a full solid on a screw. The screw turn only. S1>S2.

If I take a cycle like that ?

Surface S1 = Surface S2 but direction are not the same, so the torque are not the same too, no ?
