He was able to build the windmill using his ingenuity and a trial and error mentality. William Kamkwamba is a fantastic example of someone who could benefit from the analysis presented in this report. This report intends to identify to best angle to tilt the blades in relation to the oncoming wind to generate the most amount of electricity. However, homemade solutions are often low-tech and have undergone little scrutiny in terms of optimization. Modern wind turbines that are commercially available have been tailored to address specific wind speeds and are capable of generating megawatts of electricity from each turbine. In lesser economically developed countries, the electricity generated by homemade windmills is often used to charge batteries and cell phones or operate lighting devices, radios and irrigation pumps. Today, they are still used for this purpose but have extended their range of uses to pumping water and electricity generation.
Originally, windmills were used to perform the grinding at mills. This rotational motion can either be used for direct work or converted again into electricity. Windmills use their blades to convert the energy in wind into rotational motion. Windmills have many functions and can be operated wherever there is access to wind. The target audience are people who cannot afford commercially available models and have chosen to build their own.The project has been selected to provide support to individuals looking to generate electricity by harvesting the wind.Flat blades are used in conjunction with vertical axis turbines and the design is generally selected when simplicity is preferred or when access to tools and supplies are limited. The angle of the blades should be optimized to convert the most amount of energy into rotational motion. The intent of this project, created in collaboration with Mech425, is to identify the best angle for flat, uniform blades in relationship to the air stream.
