CHAPTER 5.
The first windmill was built by Heron of Alexandria in the 1st century. It was
the first time wind had been used to power a machine in history. The first few
windmills were built by Persians. Windmills were used a strong points in
fortifications. A windmill is a structure or machine that converts wind into usable
energy through the rotation of a wheel made up of adjustable blades. The
energy generated by a windmill windmill has been used to grind grain into flour.
They are designed by skilled craftsmen. The energy windmills produce can be
used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds.
Wind power machines today are used for generating electricity.
