The Old Windmill
Painting - Acrylic On Canvas
A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails. Originally, windmills were developed for milling grain for food production. In the course of history, the windmill machinery was adapted to many other industrial uses. An important non-milling use is to pump water, either for land drainage or to extract groundwater.
The windwheel of the Greek engineer Heron of Alexandria in the first century AD is the earliest known instance of using a wind-driven wheel to power a machine. Another early example of a wind-driven wheel was the prayer wheel, which was used in ancient Tibet and China since the fourth century. It has been claimed that the Babylonian emperor Hammurabi planned to use wind power for his ambitious irrigation project in the 17th century BC
The smock mill is a type of windmill that consists of a sloping, horizontally weatherboarded tower, usually with six or eight sides. It is topped with a roof or cap that rotates to bring the sails into the wind. This type of windmill got its name from its resemblance to smocks worn by farmers in an earlier period.
