A lift and drag-based vertical axis wind turbine in which the vertical axis and foils mounted thereon are magnetically levitated above the turbine's base, thereby reducing friction within the system. The foils or vanes are three-dimensionally shaped about the vertical axis so as to resemble the billowed sail of a sailing ship and capture wind through 360 degrees of rotation under any wind condition. The system has an axial flux alternator using variable resistance coils which can be individually and selectively turned on or off depending on wind conditions and electrical draw requirements. The coils can also be used to produce mechanical drag on the system as desired to brake the turbine in high wind conditions or for maintenance. The system may be programmed to assess whether electricity generated by the system can be or should be transmitted to a public grid or stored locally on a chargeable battery system.
