Abstract

A multi-rotor vertical axis wind turbine (VAWT) adaptable to changing wind directions, wherein according to the preferred embodiment, a main axis is surrounded by and operationally connected to three vertically oriented secondary rotors and airfoils, wherein each secondary rotor is defined by three unique blades in a strategic arrangement designed to facilitate targeted air circulation, and wherein an on-board self-regulation system enables efficient energy production in a wide range of wind speeds.
