When talking about a windmill, in the present day we generally refer to that machine utilized to convert wind energy into mechanical energy.
Looking back in the previous years, we observe that the first practical windmill, that looked rather distinct than the actual concept of what we these days call a windmill, was the vertical axis windmills. They were formulated in eastern Persia, somewhere around the 9 th century, despite that there are certain stories telling that in the 634-644AD this type of machinery was already being used. A similar windmill was used in China in the 13 th century.
The vertical windmill was developed in northwestern Europe, more precisely in northern France, eastern England and Flanders, during the late part of the 12 th century. These windmills were utilized to grind cereals and their particularity was that the complete body was in motion, unlike the tower mills that appeared in the 13 th century, and had only a part that was rotating, called the timber cap.
An additional windmill type is the smock mill, created in England, in 1745, and which is a variation of the tower mill. In those days, windmills started to be utilized for various tasks, such as grain grinding, sawmills, threshing, for land seepage or water supply.
Windmills had a very important contribution in enabling the cultivation and the ranching of large areas of North America. In addition, they were used to expand the rail transport across the world, as they were pulling water from wells to supply steam locomotives. In Canada, They were part of fortifications. One of the most memorable ones, was the one from Fort Senneville, also referred to as the "most substantial castle-like fort".
Nevertheless, with the industrial revolution, the windmill's place as an energy source was replaced by internal combustion and steam engines. Of course, despite of being an imminent step in the development of technology, all of these sources of energy became grave pollutant factors.
That is why, nowadays people tend to come back or to find alternative energies, to stop the destruction that toxic gases have delivered to our planet. Wind and solar energy are becoming our favorites these days and individuals are willing to make financial sacrifices in order to make a long-term investment that in addition to helping them decrease their energy bills, is 100% ecological.
Much like in other areas, the old-fashioned trends are coming back, and when talking about energy, this is accurate too. People have started to realize the damage they have caused to our planet, and try to change this. The fantastic, old windmill is now reborn and capable to help us get the Earth back on feet.
