Abstract: A turbine is provided which effectively converts the kinetic energy of the wind, after its (wind) accelerating, to electrical power. The multi-stage wind turbine, which allows multiple accelerate directed air flow (wind), even of most minimal speed, up to strong wind and convert it's energy into electrical power, is proposed. It is achieved due to modularity of installation, where the wind is accelerated within each module due to the processes of capturing the initial wind flow, injection-ejection and aerodynamic Coanda effect as well, by virtual necks and conical confusors nested one into another. The system of truncated cones and virtual necks with optimum aerodynamic sizes provides the capture of the airflow not only perpendicular to the base of these cones, but also from lateral sides of these cones.
