MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641018210 A) filed by Vel Tech Multi Tech Dr Rangarajan Dr Sakunthala Engineering College; Dr. Muthukumar S; Dr. M. Selvam; Prasanna S; Jeevadharshan S; and Paul Moses E, Chennai, Tamil Nadu, on Feb. 18, for 'pendulum based vortex bladeless wind energy system.'
Inventor(s) include Dr. Muthukumar S; Dr, M. Selvam; Prasanna S; Jeevadharshan S; and Paul Moses E.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "This project presents the design and development of a bladeless wind turbine that generates electrical power using the combined principles of vortex-induced vibration (VIV) and piezoelectric energy harvesting. Unlike traditional wind turbines that rely on rotating blades, the proposed system uses a vertical cylindrical mast that oscillates when subjected to natural wind flow. These oscillations are produced due to vortex shedding, also known as the Karman vortex effect. The mechanical vibrations generated are converted into electrical energy using piezoelectric materials, which produce voltage when mechanically stressed. The bladeless design offers several advantages, including silent operation, low maintenance, minimal mechanical wear7~and enhanced safety, making it suitable for urban, -rooftop, -and low-wind-speed environments, A power conditioning circuit is integrated to rectify and store the generated energy in a battery or capacitor for powering small loads. The proposed system demonstrates a compact, eco-friendly, and cost-effective approach to micro-wind energy harvesting, promising significant potential for distributed renewable energy applications."
