A water pumping windmill is simple, and efficient. The blades of the windmill wheel catch the wind, which turns the rotor. The wheel assembly is attached to a hub assembly, which drives a geared mechanism that converts the rotary motion to an up-and-down motion. This motion drives a pump rod, up and down inside of a pipe in the well.

Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.

The 400 cm2 blades were second best in generating 51.3 dc milli-amps. If you put the hub of the windmill and have the blades attached to it, it will show that the span of the 400 cm2 blades are bigger than the wind generator. This could explain why the 400 cm2 blades did not create as much electrical current as the 300 cm2 blades.
