• ### WindmillWikipedia

A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades specifically to mill grain () but the term is also extended to windpumps wind turbines and other applications. Windmills were used throughout the high medieval and early modern periods the horizontal or panemone windmill first appeared in Greater Iran during the 9th century

For instance if the blade is making 100 watts and the generator is making 100 watts that s a perfect match. Unfortunately this is very unlikely. We have to deal with a wide range of rpm s and there is always an imbalance somewhere in the range. You have to design the blade to work within the average wind speed of your area.
