How it works? - Vortex Wind Turbine in a Nutshell

The idea behind Vortex wind turbine is that it is possible that same forces can be exploited to produce energy. When the wind vortices match the natural frequency of the device's structure it begins resonating, hence oscillating, so the bladeless wind turbine can harness energy from that movement as a regular generator.
