Innovation Summary: This vertical axis wind turbine (VAWT) features a cylindrical core aligned along a longitudinal axis and configured to rotate via incident wind. A pair of diametrically opposed airfoils wraps around the core in a double-helical shape, creating distinct wind collection and drag sides. A wind deflector mounted to the frame redirects wind from the drag side to the collection side, enhancing efficiency. The turbine integrates a dowel-supported rotating core, a generator-driven gearbox, and a wind vane for dynamic deflector alignment.
Challenges / Opportunities: Urban wind energy harvesting is hindered by traditional turbine size and inefficiency in street canyon wind flows. This design leverages accelerated urban wind gusts by optimizing collection through helical airfoils and deflection mechanisms. The compact and mountable frame allows installation on vertical structures, making it suitable for dense city environments. Opportunities exist to scale the system for distributed renewable energy generation in urban infrastructure.
Key Benefits / Advantages: ✔ Enhanced wind capture via double-helical airfoil design ✔ Wind deflector improves efficiency by redirecting drag-side wind ✔ Compact frame suitable for urban installation ✔ Integrated generator for direct power conversion ✔ Wind vane enables adaptive alignment with wind direction ✔ Modular system supports multiple turbine configurations
Applications: • Urban renewable energy systems mounted on buildings or infrastructure
