  • Selectively perceptible wind turbine system
    Patent number: 9995282
    Abstract: A selectively perceptible wind turbine system provides illumination in a low intensity and wavelength invisible to the human eye, but visible to certain bats. This illumination deters bats and other flying animals from going near the turbine without becoming a nuisance. At least one ultraviolet (UV) illumination source produces at least one UV beam with a wavelength of approximately 200 nm to approximately 400 nm. This UV beam extends between the UV illumination source and at least one turbine blade surface of a turbine blade. Contact between the UV beam and the turbine blade surface forms an illumination interface with a power density of less than 100 ?W/cm2.
    Type: Grant
