The device captures the energy of vortices, an aerodynamic effect that has plagued structural engineers and architects for ages (vortex shedding effect). As the wind bypasses a fixed structure, its flow changes and generates a cyclical pattern of vortices. once these forces are strong enough, the fixed structure starts oscillating. Instead of avoiding these aerodynamic instabilities our design maximizes the resulting oscillation and captures that energy. India is having fifth largest installed wind power capacity in the world. As the regions with high wind speed are limited, the installation of conventional windmill is limited. Windmills that would provide safe, quite, simple, and affordable and work on lesser. Wind speeds are need of the hour. The Bladeless Windmill is such a concept which works on the phenomenon of vortex shedding to capture the energy produced.该装置能够捕获涡旋（vortex）的能量，这是一种长期困扰结构工程师与建筑师的空气动力学效应——涡旋脱落效应（vortex shedding effect）。当气流绕过固定结构时，流场会发生改变并产生周期性涡旋模式。当此类作用力强度足够时，固定结构便会开始振动。本设计并未规避此类空气动力学不稳定性，反而将由此产生的振动最大化，并借此捕获能量。印度的风电装机总容量位列全球第五。由于高风速区域分布有限，传统风力发电机（conventional windmill）的装机规模受到制约。当下亟需能够安全、安静、简便且成本低廉，并可在较低风速下运行的风力发电机。无叶片风力发电机（Bladeless Windmill）正是基于涡旋脱落效应捕获风能的此类设计概念。
