Abstract
Traditional wind turbines with blades have been the primary method for harnessing wind energy for decades. However, they come with several limitations, including noise pollution, bird strikes, and visual impact. In recent years, bladeless wind turbines have emerged as a promising alternative. These turbines utilize a fundamentally different approach to capture wind energy, relying on vortex-induced vibrations (VIV) rather than traditional rotating blades. This abstract presents an overview of bladeless wind turbine technology, focusing on its design, working principle, advantages, and challenges. Instead of using large rotating blades, bladeless turbines employ slender, flexible structures that oscillate in response to the wind's vortex shedding. This oscillation generates electricity through an electromagnetic induction mechanism, similar to traditional turbines. The absence of rotating blades eliminates noise pollution and reduces the risk of bird strikes, addressing key concerns associated with conventional wind turbines. Additionally, bladeless turbines have a lower visual impact, making them more suitable for installation in residential areas and sensitive ecosystems.However, bladeless wind turbines also face certain challenges. Their efficiency is currently lower compared to traditional turbines, primarily due to limitations in capturing wind energy across a wide range of wind speeds. Furthermore, the scalability and cost-effectiveness of bladeless turbines need to be further optimized to compete with conventional wind energy technologies. Despite these challenges, ongoing research and development efforts are focused on improving the efficiency, reliability, and cost-effectiveness of bladeless wind turbines. With continued advancements, bladeless turbines have the potential to play a significant role in the transition to a sustainable and renewable energy future.Keywords: Bladeless wind turbine, vortex-induced vibrations, renewable energy, sustainability, wind energy, technology.
