WINDLICHT by Roosegaarde

WINDLICHT is the latest artwork by Roosegaarde which shows the beauty of green energy by connecting windmill blades with lines of light. Special software and tracking technology detect the windmill blades rotating at 280 kilometres per hour. Visitors can tune into radio canal WINDLICHT FM 105.3 FM to hear the stories behind the artwork. WINDLICHT creates the missing link between the Dutch and the beauty of our new landscape.
