Abstract: A novel window mill vertical axis wind turbine (VAWT) is introduced to utilise the maximum wind power to produce the electricity. The novel design improves the conversion ratio by overcoming the pressure imbalance on the existing blade design with maximum utilisation of wind energy and is capable of generating power, which is three times greater than the existing windmill design. The proposed window mill is enveloped by metal case with subways and huge walls on both sides to run the turbine even during low wind head for ensuring higher efficiency than existing windmills. A complete layout of VAWT blade design is presented including the calculation of theoretical maximum efficiency, practical efficiency, propulsion and blade loads. The ANSYS simulation and experimental results are presented. These results encourage and reinforce the conviction that vertical axis wind energy conversion systems are practical and potentially very contributive renewable energy system to produce the electricity. In addition, artificial intelligence-based vertical axis wind turbine is found to provide higher performance for wind speed with economical. The proposed window mill with metal case is capable of improving the efficiency by 52% even for low heads of wind speed.
