History/ Evolution of the Windmill
Panemone (Persian Windmill)
-Persians used wind powered mills to mash up grains. The Persian windmills are directly connected to grind stones, so that when the blades spin, grains are mashed upon them.

European Postmill
-Later in Europe, windmills powered machines by transporting the energy through gears. The blades were horizontal and angled inward to catch better wind. The structure that held the blades had a maneuvering pole so as to move the windmill in the direction of the wind.

Smockmill
-The next generation of the windmill was the smock mill. The structure was slanted horizontally, then had a rotating roof that held the blades and made it easier for it to face the wind.

Dutch Windmill
New design of the tower windmill:
-the sails were improved to create aerodynamic lift which increased the rotor speed and made grinding more efficient
-the poles seen in the image are all connected to a wheel to steer the rotor in the direction of the wind

American Midwest Windmill
-this design had steel blades which were lighter in weight and easier to form into shape
-these served the purpose of water pumping during the 19th century
-in the 20th century they were used to create electricity

The Modern Windmill (Wind Turbine)
-three blades face the wind, connected to a shaft that's connected to a generator to produce electricity
-larger sizes are used to generate electricity whereas smaller ones pump water
-the speed at which the blades are turned are amplified through gears which allows for the generator to produce electricity
