“You are claiming work is being done and it generates surplus energy. Laws of Physics are just the opposite.”
Work is being done on the air and on the turbine blades. What does “generates surplus energy” mean?
Anyway ...
Energy from the moving air is converted to electrical energy by the turbine. The air exiting the turbine has lower energy than the air entering the turbine. Do you disagree?
How does the air leaving the turbine differ from the air entering the turbine? Answer: its molecules are moving slower. That can manifest itself as lower velocity or lower temperature. Do you disagree?
No. Velocity is not an energy level.
Velocity gives potential energy, relative to other objects, similar to gravity if an object is raised above a surface.
Unless an object interacts with another object at a different velocity, there is no difference than being at rest.
The mass of air moving at 50 mph only has potential energy to striking objects at rest. The air molecules colliding with other air molecules traveling at the same speed are no different in potential energy than those at zero velocity.
Those same air molecules are spinning at velocity with the earth's rotation, as well as around the sun. Velocity only has meaning in relative terms to other objects. It does not raise or lower the temperature of the object.
