Abstract
A system and method for a piezoelectric-based vertical axis wind turbine (VAWT) are disclosed. The piezoelectric-based VAWT may generate electricity in response to a deformation (e.g., a stretching or bending) of piezoelectric material. For example, the piezoelectric material may be included on or within a wind turbine blade. The wind turbine blade may be struck by an object or may hit an object. Such an action may cause the wind turbine blade to vibrate and subsequently cause the piezoelectric material to deform and generate electricity.
Claims16
An apparatus comprising:
- one or more wind turbine blades configured to rotate along an axis, the one or more wind turbine blades comprises at least some piezoelectric material;
- one or more objects in a path associated with the one or more wind turbine blades, wherein the one or more wind turbine blades strike against the one or more objects in the path as the one or more wind turbine blades rotate along the axis so that the piezoelectric material is associated with at least some mechanical stress in response to the striking of the one or more wind turbine blades against the one or more objects.
A system comprising:
- a plurality of blades to turn or rotate in response to a wind force;
- a rotor coupled to the blades and to rotate in response to the rotating of the blades;
- and
- an electricity generation component placed such that at least a portion of the rotor applies at least some mechanical stress to the electricity generation component as the rotor rotates.
1 more element
A wind turbine blade, comprising:
- a first portion that is not covered by piezoelectric material;
- and
- a second portion that is covered by at least some piezoelectric material.
