Abstract
An improved HVAC vent is disclosed. The vent may include an air turbine positioned within a passageway for selectively enabling and preventing airflow. In use, the air turbine is selectively operable between first and second states. In the first state, the air turbine may be freely rotatable, via the airflow, so that the received airflow can move through the passageway. In the second state, rotation of the air turbine is controlled or prevented so that the received airflow is inhibited or substantially inhibited from moving through the passageway. The vent may also include a motor. In use, the motor may act an energy generator and as an active brake so that in the first state, rotation of the air turbine is used to charge a power storage unit, and in the second state, the motor limits rotation of the air turbine.
