In-Depth Information
Probably the prototype NIVE wind turbine was the very first in
Denmark to have a wind vane and electrically powered yaw motor,
another of Juul's principles, whereas most other people preferred
free yawing—the yaw motor consumed power, the argument went.
The NIVE contribution to the general wind power development
was a low noise and efficient blade and the fact that HM Automatic
could deliver windmill controls to the various wind turbine
developers. Blades and controls now were available and supplied
among others to the Herborg blacksmith Karl Erik Jørgensen
and Henrik Stiesdal for their joint design work that was going to
be the first Vestas windmill.

Lessons Learned
High school teacher Kaj Fjendbo Jørgensen wanted to buy the
first wind turbine of NIVE design. HP Maskinfabrik in Thisted
assembled it, thus becoming the producer of the windmill; the same
task could just as well have been undertaken by one of the many
other blacksmiths in the local area. They would very well have been
able to screw it together.
The wind turbine design knowledge, the selection of com-
ponents and coordination was within the NIVE group members,
who were neither teachers, like in Tvind, nor do-it-yourself people.
It was a working group, a model of which was to be found in the
beginning of the century in Askov, where Poul la Cour put his
constructions at the disposal of the SMEs of the Danish people.
In the NIVE team we saw our eforts as a follow-up of the la
Cour tradition. Our research and design work was available in the
form of detailed construction manuals and drawings. There were
no patents and all-important components were commercially
available at competitive prices. With modest requirements for
engineering and tooling SMEs, without previous experience in wind
turbine manufacturing, within a few months could bring a state-
of-the-art wind turbine to the market and as their own brand.
After having been exhibited in the local Sjørring Hall, Fjendbo's
22 kW windmill was erected and plugged into the grid. From the
beginning it worked in a satisfactory manner with astonishingly
