EGL HT-400 wind turbine 400W in a built up area. This wind turbine is still effective given such close proximity of surrounding obstacles.
The wind turbine is part of a wind-solar hybrid street light system installed in new Sau Mau Ping housing estate in Hong Kong.
Low frequency noise is the wind against video camera's microphone. High frequency noise is from the spinning rotors, insignificant in the ambience of urban noise.
