Poul la Cour was a pioneer in the field of aerodynamics and is known for his development of windmills for electricity generation. With his wind tunnel experiments, he developed the theory for the ideal windmill blade profile and discovered that the airflow behind the blade was just as important as the wind’s forward pressure. Poul la Cour also studied the potential of storing wind energy in hydrogen and oxygen by electrolysis.
His Askov research centre from 1897 functions today as a museum of Danish wind turbine history as well as a classroom for natural sciences. Visitors can do experiments with wind energy, energy storage by electrolysis of water to hydrogen and oxygen, fuel cells, solar cells and other forms of renewable energy. Poul la Cour’s Test Turbine is owned and run by the Poul la Cour Foundation.
