Can Wind Energy Be Bird Safe?
Nearly every week, Kimberly Kaufman receives messages from birders and conservationists alerting her to new wind energy designs that bill themselves as safe for wildlife. The technologies come in all shapes and sizes and are in varying stages of development. Yet each claims to do one thing that conventional wind turbines can’t: harness the incredible power of wind without killing birds.
Taking a Different Approach with Wind
One of the new companies is SheerWind, whose Invelox technology harvests wind energy even in areas where airflow is minimal. Invelox captures wind by funneling it through tubes that “squeeze” the wind and increase its speed, much in the same way that putting one’s finger over a garden hose will accelerate the flow of water. Then multiple turbines located inside the structure generate power from the magnified wind speed.
