Design of New Domestic Wind Turbine

Horizontal axis wind turbine is a productive machine that produces electric power from renewable energy source, farms of wind turbines is a great source of power with some disadvantages. Domestic small scale wind turbines have their advantages and disadvantages. They are more practical than large scale wind turbines which have visual impact and can contribute to disruption of wild life for birds. Domestic horizontal axis wind turbine proved that it is not useful for domestic use because of its high noise level and low wind speed in the domestic areas. A new modified design of domestic vertical axis wind turbine has been proposed, it uses a direct drive technology. Theoretically the helical vertical axis wind turbine produces high power output. It can meet the demand of a small house with an aid of storage batteries, and the design fits in the backyard garden with less visual impact. The creative thinking tools, design analysis, selection methodology and concurrent costing software were all used to come up with the design. CAD model and assembly design model were prepared; stress analysis was conducted for the main frame. Rendered image for the final product was prepared to check visual impact. Finally pay back estimate table for the product showed that within a reasonable time the product will break even.
