transportation machinery. Nordtank, originally a tank producer,
started as well with the 22 kW turbine and the same blade
profile but used its expertise in rolling and welding large tank
sections in order to produce a “welded tube” tower which
eventually replaced the lattice towers of NIVE and Herborg
designs to become part of the standard design configuration.

originally tried to license the Nordtank technology but then
developed their own design with Maegaard serving as consultant
to the firm as well as a board member for a time in the early
years. From these origins, all linked to NIVE, Tvind, OVE and Riisager,
the “Danish Concept” became pervasive in early Danish wind
manufacturing and eventually obtained its status as the dominant
design within the industry. Even Tacke, a German wind turbine
manufacturer, has its origins in a jointly funded program by the
EU for the creating a new 400 kW generator. In 1988, both
Nordtank and Folkecenter submitted proposals but Nordtank
won the contract due to their manufacturing base. However, when
Nordtank went bankrupt, the project was turned over to NIVE's
descendant, the Nordic Folkecenter, provided that they work
with a manufacturing firm, the German company Tacke, with the
project cost share of 2/3 and 1/3, respectively. From this project,
Tacke moved into the wind space and was eventually acquired
by Enron Wind and then by GE Wind, when Enron went bankrupt.
