Vertical Sky® is the first megawatt-class wind turbine whose quiet and bird-friendly design enables electricity generation directly at the point of consumption.

Vertical Sky® operates with three rotor blades that rotate around a vertical axis. The individual blades constantly adjust to the direction of the wind, ensuring they are always optimally aligned with the airflow. This dynamic alignment allows them to maintain consistently high efficiency – no matter which direction the wind is coming from. As a result, wind energy is always converted into electricity as efficiently as possible.

A test facility that replicates the Vertical Sky® principle on a scaled-down basis is located in Switzerland. Standing 23 meters tall and 6 meters in diameter, this facility has been operating automatically since February 2025. Comprehensive measurement data is collected here, which is directly used to optimize efficiency and performance.

The test facility thus provides the ideal foundation for further developing the technology under real-world conditions and perfecting it for future use.
