In this paper capturing of wind energy using bladeless device which is a new approach has been discussed. The energy of vorticity which is an aerodynamic effect has been captured by this device. A cyclical pattern of vortices has been generated when the wind bypasses a fixed structure and the fixed structure starts oscillating when these forces are strong enough. Without avoiding these aerodynamic instabilities this device maximizes the resulting oscillation and captures that energy. Naturally, such device is completely different from traditional turbine. Instead of the usual tower, nacelle and blades, the device has a fixed mast, a power generator and a hollow, light weight and semi-rigid fibreglass cylinder on top. In this device the technology has been used is very cost effective and highly competitive not only against generations of alternative or renewable energy, but even compared to conventional technologies.
