The natural frequency of the structure should not match with the frequency of vibration, which is one of the design criteria, our design takes care of this major criteria. The design of our windmill is entirely different from a traditional windmill. ... Installation cost and maintenance cost low compared to blade wind mill. It p r o d u c e s l ...

Wind turbines like all other mechanical equipment generate sound. A relative comparison of the sound from a wind turbine at 350m is given in Table 1, figures are Sound Pressure Levels. The sound generated by a wind turbine covers a broad spectrum of frequencies including infrasound and low frequency.

Understanding the vibration . 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 ...
