The wind turbine funnel includes a frame rotatably mounted to support about a rotational axis. The frame includes an inlet having a funnel directing incoming wind towards a turbine wheel disposed adjacent the funnel. The funnel includes an angled upper, main deflector and an optional, angled lower deflector disposed between side panels. The turbine wheel includes a plurality of curved wind blades radiating from the axis of the wheel. The blades are configured to maximize conversion of the wind energy into rotational force for the wheel. The center of gravity of the frame and turbine is disposed behind the rotational axis to permit free rotational adjustment of the frame with respect to wind direction with minimal force. The side panels may include raised sections that function as a rudder.
