This paper proposes to construct a wind turbine that has a very low cut in speeds and aims to optimize the earlier model of Vertical axis wind turbine (VAWT). A wind turbine is a device which is generally used to convert wind energy into mechanical energy, which is in turn converted into electrical energy. Wind turbines are broadly classified into two types: Horizontal axis wind turbine (HAWT) and Vertical axis wind turbine (VAWT). For the optimization of the earlier model of VAWT, using the curved blades made of acryl polymer which reduces the drag force and overcomes the problem of poor starting. In VAWT, the mechanical power generation equipment can be located at ground level, so it makes the maintenance easy and they are omni-directional (they do not need to be pointed in the direction of the wind to produce power).
