Significance of the turbine
In its own field the Halladay's wind turbine represented the most progressive drive in Moravian wind milling. It reached the culmination of the development of wind milling both in the technical constructional side and in the working side. From a stand-point of its efficiency it was comparable with its constructional successors - steel multivane wind turbine system ECLIPSE, which were produced first by Kunc's factory in Hranice and which were exported all over Europe.
Why did it not come to wider use? That motor has, compared with its predecessor, indisputable advantages.
There are several reasons why Halladay wind turbines were not widely used: First was the construction and its expensiveness, made out of metal and wood with a great number of components (rimes and spokes of the runner, hinged shutters, drew bars, levers and weights, load-bearing structure, tail vanes and cone pulley drive).
All those components against the traditional wind mill vanes with a cop wheel and the unusual construction which was not known in general to master-builders at that time.
Secondly, there was a strong competition in the alternative drives coming into miller's trade at that time - water turbines, gas engines, compression ignition engine and finally electric motor, which came to general use from the 1890s.
Finally - this wind turbine succeeded in the end of the wind milling development in Moravia and Silesia. Windmilling at that time was legging behind water milling. Especially the dependence on the mill location and on favourable winds obstructed an easy transport of a grist to customers. All those facts reduced the wind millers' ability to compete against millers working with other drives.
In spite of these facts Ruprechtov wind turbine exemplified a progress in the development of our wind milling and of our ancestors endeavour to keep pace with contemporary technology in the world.
