A wind turbine with a stationary tower and a set of turbine blades rotatably attached to the top and bottom of the tower. A set of upper and lower braces connects the turbine blades to prevent any sag or skewing of the turbine blades as they rotate about the tower. The wind turbine may also include a stationary shell attached to the tower and inside the sweep of the turbine blades, to direct the airflow toward the turbine blades at the shell periphery, thereby improving overall performance and efficiency of the turbine.
