Wind Turbines

Erich Hau has gained experience over decades designing wind energy converters with a major industrial manufacturer and, more recently, in technical consulting and in the planning of large wind park installations, with special attention to economics.Sönke Siegfriedsen has designed and built his first wind turbine while writing his thesis. 4 years later - 26 years old – he has founded his engineering office aerodyn in1983. In the following 40 years, the engineering team has developed almost 30 different types of wind turbines with up to 10,000 kW for companies around world. To date, these companies have manufactured more than 60,000 turbines according to aerodyn documents. During these years Sönke Siegfriedsen made numerous inventions which resulted in more than 350 patents.
