Wind energy can be converted to electrical energy in a windmill. Such a device features a large propeller that can be moved into the direction of the wind. Friction with the wind will cause the propeller to rotate. The propeller is internally connected to a dynamo which converts the rotational energy into electricity.
It is the opposite to the way how old airplanes were propelled. They use the propeller. When the propeller is exposed to the wind it rotates automatically. (Compare with the boat propeller and water turbine.)
Wind energy is dangerous to birds, if a propeller hit a bird, the bird would likely die.
Yes, elastic energy is a type of energy.
It is a type of mechanical energy. It is energy due to position ofobject

You could, but then you would be generating additional drag. This would most likely require more energy to overcome than the energy generated by the windmilling propeller.

A uni-rotating propeller is one that can go around in both directions. This type of propeller typically will do different things depending on which direction it is going.
Inclined plane

It depends on the type and weight of aircraft, power of engine and type of propeller.
Check out the Instructables website and type in "Propeller-Powered Car" on the search window. The instructions for it will come up along with a video.
The propeller on a submarine is properly called the screw. It's a multi-bladed hydrofoil that converts the rotational energy of the shaft to propulsion. Links can be found below for more information.
The 757 is a jet airplane. It does not have propellors.
