Acknowledgement
I’m happy to say that I chose this topic as I learnt a great deal of information while writing this report. It was while developing the working model of Windmill that encouraged me to do research that lead to this report. Thank you Wikipedia. As always, I prevailed upon my Teachers to provide me the knowledge. They taught me how to think and apply that to my work. Rebecca Maam, my science teacher, has been with me from the beginning. She is insightful, thoughtful and encouraging. When I think of what she has done for me, I feel very lucky to have such a good teacher. I owe thanks most of all, to my parents. Without their support and encouragement, it would not have been possible for me to write this report.

Introduction
A windmill is a three bladed machine which converts the energy of wind into rotational energy by means of blades. Originally windmills were developed for milling grain for food production. In the course of history the windmill was adapted to many other industrial uses. An important non-milling use is to pump water, either for land drainage or to extract groundwater with wind pumps. Windmills used for generating electricity are commonly known as wind turbines.

Topic
A windmill is an engine that is powered by the wind to produce energy. Often they are in a large building. The energy windmills produce can be used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds. Modern wind power machines are used for generating electricity and are more commonly called wind turbines. A windmill is one of the most energy efficient ways to pump water from the...
