Rooftop wind-solar hybrid solution would go a long way. Large conventional Horizontal Axis Wind turbines are suitable only for areas with horizontal non-turbulent wind. Small wind turbines installed in areas with good wind resources can generate more than other decentralized energy sources. High efficiency Vertical Axis Wind Turbine with dynamic blade pitch change has the ability to give optimal performance across a range of wind speeds. Minimum viable product prototype is completed (80% done) Variable pitch change mechanism has been added.
