Inspiration
Espantalho Eólico was inspired by the growing conflict between renewable energy expansion and biodiversity conservation. While wind energy is essential for climate goals, bat mortality around wind turbines remains a significant environmental challenge. We wanted to explore a solution that supports clean energy without increasing ecological impacts.
What it does
Espantalho Eólico is a passive ultrasonic deterrent that uses wind energy to generate variable ultrasonic sound, alerting and discouraging bats from approaching wind turbines.
How we built it
Not yet built, but ungoing design a wind-driven aerodynamic whistle, inspired by biomimetic research, capable of emitting ultrasonic frequencies without electronics or external power.
Challenges we ran into
The main challenges were research related. Different contradicting informations, less-studied recent wind turbines.
Accomplishments that we’re proud of
We developed a technically feasible, low-cost, and scalable mitigation concept.
What we learned
We gained insight into wind engineering, bioacoustics, and environmental mitigation design.
What’s next for Espantalho Eólico
Next steps include prototype testing, acoustic validation, and field trials in real wind farm conditions
