Innovative wind turbine enters test phase
VentoStream is about to start trial operation of its compact, efficient and quiet wind turbines. They combine modern aerodynamics with flow and turbine technology. The beta version of the prototype will be tested in 2025 in the Basel region and at a high alpine location.
VentoStream is currently finalising the beta version of the first upscaled prototype of its novel wind turbines and is planning a test phase for this year. Founded in 2023, the company has developed a technology based on almost twelve years of development. VentoStream describes its turbines as an “innovative product for producing electricity from wind without side effects”.
According to the company, VentoStream turbines eliminate many of the disadvantages of conventional propeller wind turbines: they are smaller and lighter, making them easier to transport and install. They also have much less impact on the landscape and are quiet. “They therefore invalidate practically all the reasons for objections to wind farms,” says VentoStream. In addition, they are mainly made of recyclable aluminium and copper. In contrast, the blades of conventional wind turbines are not recyclable.
VentoStream technology is based on classical fluid mechanics, aerodynamics and modern turbine technology. It consists of different system units which, in combination, are designed to generate considerably more power than conventional propeller wind turbines. VentoStream names companies that want to generate their own electricity, power stations, the public sector, mountain railways and piste operators, railways and solar companies as potential users.
The two-stage test phase is set to begin in summer 2025. According to the company, the first tests will be carried out at a site in the Basel region. The aim is to optimise functionality and validate the performance curve. “In the second stage,” says CEO Manuel Bernsau, “we would like to test the wind turbine at a high alpine location.”
