The intent of this project, created in collaboration with Mech425, is to identify the best angle for flat, uniform blades where the primary use is for homemade windmills where there is little access to tools or when simplicity is preferred.

[http://www.ted.com/talks/lang/eng/william_kamkwamba_how_i_harnessed_the_wind.html William Kamkwamba] is a fantastic example of who could benefit from the analysis presented in this report. His ambition for a better life and access to scrap materials was transformed into a working device that provides both light and irrigation to his community and inspiration to the rest of the world. As more people begin to develop solutions for their own energy needs, there is great value in optimizing these devices to maximize their social benefit.<br><br> William's story can be viewed below:

The angle is adjusted in radians and seems to indicate a maximum value at approximately 0.62 radians, or roughly 35.5 degrees. This translates in a maximum conversion of 38.5% of the wind force into rotational motion. Therefore, the blades should be tilted at an angle of roughly 35.5 degrees from the oncoming air stream to obtain the optimal amount of energy using flat blade windmills.

If you happen to have access to additional equipment such as saws, then it may be possible to use the design shocased in the video below. Also, be sure to note that the wind turbine is able to pivot and uses a tail to direct the blades into the wind.
