The Eco Whisper is a low noise wind-turbine, looking more like a jet engine compressor blade than a conventional large aircraft wing-type wind-turbine attached to a hub.
The Eco Whisper is installed at Geelong, Victoria, Australia, and is designed by Renewable Energy Solutions Australia Holdings Ltd, Brisbane, Australia.
The wind turbine uses an automatic slewing mechanism to keep the blades pointing into the wind, and can generate 20kW of power. The Eco Whisper is 21.1m (69.2ft) tall with 6.5m (21.3ft) diameter blades, fitted with an outer cowling that is designed to prevent spanwise airflow, increasing the 30 aluminum blade lifting efficiency and helping generate more power at a given wind speed.
The shorter blades and cowl are claimed to reduce bird deaths and the hinged tower allow the turbine to be maintained or lowered when there are storms.
