Wind energy is an emerging technical field. Only about 30 years ago it was "rediscovered". Initial trials with large-scale systems such as the NASA MOD or Growian failed due to technical or economic barriers. Only by the tireless work of a small number of convicted persons the small wind turbines could grow to today's power plants. Countless technical improvements made the current WEA true wonders of economy. Thanks in particular to the company REpower and Svendborg Brakes, which allowed me to publish some of my inventions.
