A wine turbine with blades having a high lift-to-drag ratio is provided. A hydraulic or other control system is used to control cone angle, such as in response to flap moment. Pitch of blades is controlled, such as in relation to the blade flap angle. Teeter motion is controlled preferably as a function of teeter angular velocity.
