A wind turbine has an internal rotor carrying a plurality of turbine vanes in a circular path between an inlet opening and an exhaust opening. The inlet opening includes a stationary dividing vane that delivers one portion of the inlet airflow to a primary flowpath traversing the turbine vanes at two locations. The stationary dividing vane also delivers a second portion of the inlet airflow to a second flowpath which drives the turbine vanes as those vanes move in the part of the circular path from the exhaust opening toward the inlet opening. The turbine vanes may be mounted so as to have variable angular positions in different portions of the circular path. Turbine vane position can be controlled either magnetically or mechanically. Where vane position is varied magnetically, a plurality of permanent magnets with suitable controls adjust the turbine vane position. Where vane position is varied mechanically, a pair of cam arrangements may be employed.
