Abstract
An apparatus includes an axle; and a blade coupled to the axle for a rotation therewith about a rotational axis, the blade comprising a wall and a peripheral edge defining, in a combination with each other, a cavity of the blade. The blade may be provided as a plurality of blades. The blade may be disposed within a hollow interior of a housing. A generator of electric energy may be coupled to the axle to convert mechanical rotation at the axle into the electric energy. The apparatus may be used to charge a battery pack and/or as a direct power source for electric motors.
Claims20
An apparatus, comprising:
- an axle, the axle defining a rotational axis;
- a blade attached to the axle for a rotation therewith about the rotational axis, the blade comprising a wall and a peripheral edge defining, in a combination with each other, a cavity of the blade;
- and
- one of:
- an opening in each of the peripheral edge and the cavity and being disposed at an end of the wall disposed furthest from the axle, and
- an extension at an end of the wall disposed furthest from the axle and a passageway in the extension, the passageway being in an open communication with the cavity.
3 more elements
An apparatus, comprising:
- a housing with a hollow interior, an air inlet in an air flow communication with the hollow interior and an air outlet in the air flow communication with the hollow interior;
- and
- a bladed rotor mounted for a rotation within the hollow interior, the bladed rotor comprises:
- an axle, and
- a plurality of teardrop-shaped blades radially extending from the axle for a rotation therewith about a rotational axis, each teardrop-shaped blade at least including a wall and a peripheral edge defining, in a combination with each other, a cavity of the each teardrop-shaped blade, and
- one of:
- an opening in each of the peripheral edge and the cavity and being disposed at an end of the wall disposed furthest from the axle, and
- an extension at an end of the wall disposed furthest from the axle and a passageway in the extension, the passageway being in an open communication with the cavity.
5 more elements
A vehicle, comprising:
- a vehicle body;
- wheel assemblies supporting the vehicle body thereon;
- a battery;
- a drive system designed to convert electric energy into a mechanical energy to rotate wheels within the wheel assemblies;
- a controller designed to receive and regulate electric energy from the battery;
- an air directing component designed to move between a first position and a second position;
- a lip on one edge of the air directing component, the lip extending outwardly from a vehicle surface to move the air directing component into the first position in a response to a presence of an air flow;
- a biasing member designed to move the air directing component into the second position in a response to an absence of the air flow;
- and
- a generator of an electric energy mounted adjacent an opening in a floor board of the vehicle, the generator designed to convert a kinetic energy of the air flow into the electric energy in a response to the air directing component being in the first position to direct the air flow toward the generator, the generator at least including:
- a bladed rotor mounted for a rotation within the hollow interior, the bladed rotor at least including:
- an axle,
- a plurality of teardrop-shaped blades radially extending from the axle for a rotation therewith about a rotational axis, each teardrop-shaped blade at least including a wall and a peripheral edge defining, in a combination with each other, a cavity of the each teardrop-shaped blade, and
- one of:
- an opening in each of the peripheral edge and the cavity and being disposed at an end of the wall disposed furthest from the axle, and
- an extension at an end of the wall disposed furthest from the axle and a passageway in the extension, the passageway being in an open communication with the cavity.
