Roof mounted wind energy collection device
A wind energy collection device configured to be mounted to the roof of a structure, the device optionally comprising: a support frame to be fixed to the roof of a building; a wind turbine impeller mounted to the support frame, the impeller supported by a turbine shaft oriented in a fixed horizontal and vertical position relative to the frame. The impeller optionally coupled to a generator to convert rotational movement of the impeller to power that can be stored and/or transmitted. The device may also comprise at least one directional panel configured to direct the wind to at least one impeller vane of the impeller such that the impeller rotates in a rotational direction due to force exerted by the wind blowing in a first direction; and the directional panel is repositionable so as to direct the wind blowing in a second direction opposed to the first direction such that the impeller rotates in the rotational direction.
1. A roof mounted wind energy collection device comprising:
a support frame configured to be fixed to the roof of a building;
a wind turbine impeller mounted to the support frame;
the impeller rotating about an axis of rotation running parallel to an adjacent ridgeline of the roof defining two separate roof surfaces;
the orientation of the axis of rotation fixed relative to the frame;
the impeller coupled to a generator configured to convert rotational movement of the impeller to power that can be stored and/or transmitted;
a first directional panel on a first end of the support frame, the first directional panel configured to direct the wind to at least one impeller vane of the impeller such that the impeller rotates in a first rotational direction about the axis of rotation due to force exerted by the wind blowing in a first direction;
a second directional panel configured to direct the wind blowing in a second direction opposed to the first direction such that the impeller rotates in the first rotational direction about the axis of rotation;
a pressure vane comprises a flag portion configured to be blown against by the wind;
the pressure vane configured to rotate about a pressure vane shaft;
wherein rotation of the pressure vane rotates a gate to partially obstruct wind from rotating the impeller.
2. The roof mounted wind energy collection device as recited in claim 1 further wherein the second directional panel is configured to reposition to a second position to cooperate with the first directional panel so as to direct the wind blowing in the second direction opposed to the first direction such that the impeller rotates in the first rotational direction about the axis of rotation.
3. The roof mounted wind energy collection device as recited in claim 1 wherein the second directional panel is mounted to the first end of the frame.
4. The roof mounted wind energy collection device as recited in claim 1 further comprising a third directional panel configured to cooperate with the first, and second directional panel so as to direct the wind blowing in a second direction opposed to the first direction such that the impeller rotates in the first rotational direction.
5. The roof mounted wind energy collection device as recited in claim 4 further comprising a fourth directional panel configured to cooperate with the first, second, and third directional panel so as to direct the wind blowing in a second direction opposed to the first direction such that the impeller rotates in the first rotational direction.
6. The roof mounted wind energy collection device as recited in claim 1 wherein the roof comprises a first roof surface at a first angle to the horizon and a second roof surface at a second angle to the first roof surface with a second angle to the horizon, the merging of the first roof surface and second roof surface forming a roof ridge parallel to the axis of rotation of the impeller.
7. The roof mounted wind energy collection device as recited in claim 1 wherein the first directional panel in a second position occludes a flow path through the support frame.
