A recently published report, Status and Expectations for Wind Energy R&D in the Netherlands, by Gijs van Kuik of Stork Product Engineering, compares present-day wind technology with that of aeroplanes in the 1930s. The basics are there, but there is a world of difference between a Dakota (DC-3) and a Boeing 737, argues Van Kuik. Research and development to fill holes in the knowledge of wind turbine behaviour under extreme conditions is very much needed, he writes. Once these are filled research is needed for development of new concepts and components, while more fundamental research is needed in aerodynamics and acoustics.
