Outside P=1bar
Take a lot of small boxes empty and closed (square at top view). Put air pressure P=2bars inside. Put an axe in each box in the center of the box. We never loss pressure, P inside box is always = 2 bars.
Take a half cylinder.
Put small boxes closed to each others on the surface of the half cylinder. We covered the surface of the half cylinder with boxes. The boxes are in staggered. Cancel one half side of box with another half side's box (cancel side and put gasket).
All boxes want to turn in the same direction (a torque exist because we have cancel 2 half sides symetrical of axe), but the axe is attach to the half cylinder so the box don't turn from each other but the half cylinder can turn.
The cylinder turn and give energy.
Note the drawings show a limited number of boxes but we can have a great number, so the slope in the top (slope at right and slope at left) view can be near 0. Like that the surface at right and at left of the cylinder is symetrical in all direction and this cancel others torques.

The side view, we can see half cylinder, boxes with axes
-------------------------------------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------------------------------------
The top view, it's a deploy view (see degrees).
-------------------------------------------------------------------------------------------------------------------------------------------------
-------------------------------------------------------------------------------------------------------------------------------------------------
2 boxes for see how are canceled the sides and the gasket.

A cylinder with a lot of boxes (not all details !!!) we can see the slope near 0
