The purpose of this book is to provide step by step methodology of designing a VAWT. The Fabrication process explained can support VAWT as conventional sources of energy in a range of small scale wind turbines, manufactured with easily available material to obtain sustainable and self-reliable source of green energy. The Aerodynamic theory involved in designing A VAWT is simplified with insight in the Forces and strength analysis. This book even shows the results obtained from a small wind turbine model in Middle Eastern countries.
