Mark II water brake windmill: Section (left); Yaw system and
power security (right).
The measurements were recorded in the report “Wind
Energy-Heat Generation” and presented in 978 at the Second
International Symposium on Wind Systems Energy in Amsterdam.
Ricard Matzen's many experiments and measurements with water
brakes resulted in mentioned reports. These, in large part, formed
the basis for the development of water brake turbines in Denmark.
