comment What do we consider “Perpetual Motion”
The real intent of my question was to verify that force added by nature does not make it "perpetual motion". I get a kick from watching the Youtubes on "free energy" sometimes is not evident where the extra energy is coming from.

comment Why do blades of windturbine propellers as comp. to propellers of ships cover very different areas?
@Georg No there is actually compressed air in front of the blade. that is way the blade moves easiest threw a gas Vs a liquid. Now the compression is relative to the speed of the blade and the motion of the plane.
