what materials do you need to make a windmill?
153955
Materials needed for the windmill are a template, scissors, straw, some yarn, some pennies, a paper cup, rubber bands, pencil, single hole punch, a skewer and thumb tacks. Take the template, cut it out along the solid lines and punch holes on the corners as shown in the video.

Experimentation with new materials for the blades has taken place. In commercial wind turbines, fiberglass with a hollow core is used for the blades; however, aluminium and lightweight woods are also used. ... The blades are normally bolted on the nacelle after placing it on the tower.

A sail is a tensile structure—made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles.

According to a report from the National Renewable Energy Laboratory, wind turbines are predominantly made of steel (71-79% of total turbine mass), fiberglass, resin, or plastic (11-16%), iron or cast iron (5- 17%), copper (1%), and aluminum (0-2%).

Wind turbines use the wind to drive turbines directly. They have huge blades mounted on a tall tower. The blades are connected to a 'nacelle', or housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator.

The answer, according to the American Wind Energy Association, is that it takes somewhere in the range of 200 to 230 tons of steel to make a single wind turbine.

A windmill anemometer is a common instrument used at weather stations to obtain the wind speed. A wind vane is used as part of the anemometer to determine the wind's direction. As the wind flows over the windmill, the speed and direction of the wind can be measured with this instrument.
