Windside Wind Turbines for
exceptional conditions
In Antarctica a German research group utilizes
Windside wind turbines for producing power for device
that record whale-noise and ”singing”. This is a great
example of the most demanding professional use in the
harshest of environments, for which Finnish Windside
Wind Turbines have been designed. Completely self
contained and automatic Windside Wind Turbines are
operating also in other extreme marine environments.
In addition to this Windside wind turbines are in use in
over 40 countries since 1982.
