Abstract

An electrical generator is provided. The electrical generator includes a support, a magnetic material configured to be coupled to the support, and at least one flexible conductive member configured to include an electrical conductor associated with the magnetic material and to move in response to a fluid flow.

Claims

1. An electrical generator comprising:

an elongate support;

a magnetic material coupled to the elongate support, the magnetic material and the elongate support defining a plane; and

at least one flexible member including a flexible film and an electrical conductor disposed on the flexible film,

wherein;

an end of the at least one flexible member is coupled to the elongate support;

the electrical conductor is disposed on the flexible film such that the electrical conductor is substantially aligned with the magnetic material in an absence of fluid flow; and

a portion of the at least one flexible member excluding the end is configured for out-of-plane movement relative to the plane in response to fluid flow.

2. The electrical generator of claim 1, wherein the at least one flexible member is configured to be apart from the magnetic material.

3. The electrical generator of claim 1, wherein the flexible film includes vinyl material, paper, or fabric.

4. The electrical generator of claim 1, wherein the electrical conductor includes a conductive ink printed on the flexible film in a coil shape or a coil-shaped thin film of copper or aluminum attached on the flexible film.

5. The electrical generator of claim 1, further comprising a bearing configured to be interposed between the elongate support and an immovable object.

6. The electrical generator of claim 1, further comprising a rectifier configured to be connected to the electrical conductor;

and

a storage battery configured to store an output current of the rectifier.

7. The electrical generator of claim 1, wherein the fluid flow is at least one of air flow, water flow, and tidal flow.

8. The electrical generator of claim 1, wherein the out-of-plane movement relative to the plane comprises movement having a component that is substantially orthogonal to the plane.

20. The electrical generator of claim 1, wherein the fluid flow comprises air flow and the at least one flexible member is configured to extend from the elongate support while moving in air flow having a speed more than 12 kilometers per hour.

21. The electrical generator of claim 1, wherein the at least one flexible member has a surface area between about 300 centimeters squared (cm²) and 750 cm².

22. The electrical generator of claim 1, wherein the at least one flexible member is configured to experience, in response to fluid flow, movement including at least one of vibrating, oscillating, waving, and shaking.

9. An apparatus to generate an electrical energy comprising:

a frame defining a plane; and

a plurality of electrical generators arranged on the frame and configured to generate an electrical energy in response to a fluid flow,

wherein each of the electrical generators includes;

an elongate support;

a magnetic material coupled to one or both of the frame or the elongate support; and

at least one flexible member including a flexible film and an electrical conductor disposed on the flexible film,

wherein for each of the electrical generators;

an end of the at least one flexible member is coupled to the elongate support;

the electrical conductor is disposed on the flexible film such that the electrical conductor is substantially aligned with the magnetic material in an absence of fluid flow; and

a portion of the at least one flexible member excluding the end is configured for out-of-plane movement relative to the plane in response to fluid flow.

10. The apparatus of claim 9, wherein out-of-plane movement of the portion of the at least one flexible member relative to the plane causes a change in a relative location of at least part of the electrical conductor with respect to the magnetic material.

11. The apparatus of claim 10, wherein the electrical conductor is configured to include a conductive ink printed on the flexible film in a coil shape or a coil-shaped thin film of copper or aluminum.

12. The apparatus of claim 10, further comprising a rectifier configured to be connected to the electrical conductor;

and

a storage battery configured to store an output current of the rectifier.

13. The apparatus of claim 9, further comprising a frame support configured to support the frame.

14. The apparatus of claim 13, further comprising a bearing configured to be interposed between the frame support and an immovable object.

15. The apparatus of claim 9, wherein the elongate support of each of the electrical generators is detachably attached to the frame.

16. The apparatus of claim 9, wherein the magnetic materials and the at least one flexible members are alternately stacked in series.

17. The apparatus of claim 16, wherein a number of the at least one flexible conductive members is greater than a number of the magnetic materials by one.

18. The apparatus of claim 9, wherein the electrical generators are arranged on the frame in a matrix.

19. The apparatus of claim 9, wherein the out-of-plane movement relative to the plane comprises movement having a component that is substantially orthogonal to the plane.

23. The apparatus of claim 9, wherein the fluid flow comprises air flow and the at least one flexible member is configured to extend from the elongate support while moving in air flow having a speed more than 12 kilometers per hour.

24. The apparatus of claim 9, wherein the at least one flexible member has a surface area between about 300 centimeters squared (cm²) and 750 cm².

25. The apparatus of claim 9, wherein the at least one flexible member is configured to experience, in response to fluid flow, movement including at least one of vibrating, oscillating, waving, and shaking.
