Abstract
Idea/Technology:
– Blade-mounted ultrasonic deterrent driven by blade-relative flow
Technology Impact:
– Mitigate bat mortality at wind farms with little-to-no reduction in energy capture
– Cost savings by replacing/supplementing operational mitigation with the proposed deterrent
Current status:
– Deterrent tested to generate ultrasound spectrum in labs
– Passive operation looks promising … design optimization pending
– Impact on bats … not yet investigated
