BACKGROUND OF THE INVENTION It has long been a goal of engineers and scientists to develop more effective methods and apparatuses for harvesting the kinetic energy that is present in naturally occurring flows of wind, water or flows of other material. The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention. In one embodiment, separation layers can be used to maintain consistent desired distance between magnetic field layer 40, first layer 60 and second layer 80. This can be useful to limit the extent to which magnetic field layer 40, first layer 60 and second layer 80 separate and to allow magnetic field layer 40, first layer 60 and second layer 80 to move along length 24 with relation to one another. In this embodiment, the intensity of the magnetic field(s) proximate to magnetic field layer 40 varies along length 24. In this embodiment, only two magnetic field sources 48A and 48B are shown, however, this is done for the purpose of simplifying the present discussion and this is not limiting.

When generator 20 is bent, roller type magnetic field sources 48A and 48B 48A and 48B reduce the friction between first layer 60, second layer 80 and magnetic field layer 40. This reduces energy losses and helps to extend the life of generator 20. Optionally, this can also be used to reorient the magnetic fields 50A and 50B generated by magnetic field sources 48A and 48B during rolling which can have the effect of increasing the extent to which conductors 64A, 64B, 84A and 84B experience a change in magnetic field strength during bending and increasing the electrical current in conductors 64A, 64B, 84A and 84B. In this embodiment magnetic field layer 40 holds roller type magnetic field sources 48A and 48B at a generally fixed separation along length 24 and enable rotation of roller type magnetic field sources 48A and 48B to reorient magnetic fields 50A and 50B. The diameter of the rollers could be varied to impact the radii differences between magnetic field layer 40, first layer 60 and second layer 80 and will impact the relative shift between magnetic field layer 40, first layer 60 and second layer 80. Roller type magnetic field sources 48A and 48B can alternatively be designed or composed of multiple fields/magnets and can provide more than two magnetic poles.

22, holder 30 is bent, first conductor 64A and third conductor 84A move to a different position relative to magnetic field source 48A of magnetic field and second conductor 64B and fourth conductor 84B also move to a different position. The first flexible array of conductors, the second flexible array of conductors and the flexible magnetic field source are then held at one end along a length but moveable relative to each other at an opposite end such that forces provided by the fluid cause the flexible magnetic field source, the first flexible plurality of conductors, and the second flexible plurality of conductors to bend along the length (step 152). Here too one embodiment this can be done by assembling an electrical generator 20 that has a magnetic field layer 40, first layer 60 and second layer 80 that are held together at mounting ends thereof as is shown in FIGS.
The flexible magnetic field source, the first plurality of conductors and the second plurality of conductors are arranged in the flow material so that any forces provided by the fluid to cause the flexible magnetic field source, the first flexible plurality of conductors, and the second flexible plurality of conductors to bend along the length (step 154) This can be done for example by orienting the flexible magnetic field source, the first plurality of conductors and the second plurality of conductors in the flow so that forces from the flow tend to vary in ways that will bend the flexible magnetic field source, the first plurality of conductors and the second plurality of conductors along the length. This can be done for example by defining airflow characteristics of airfoil 306 to create a low pressure along at least one the sides of the device which might serve to align the device into the flow as well as creating turbulence.
When this occurs piezoelectric layer on one side of the structure is bent into a convex shape and a dielectric layer on the other side is bent into a concave shape. Causas de dolor de espalda media . Jun. 7, 1983, entitled: “Piezoelectric Fluid-Electric Generator” which shows a piezoelectric fluid-electric generator including a piezoelectric bending element, means for mounting the one end of the belt the elements in a fluid system, means for driving the piezoelectric element to oscillate with the energy of a fluid stream and electrode means connected to the piezoelectric ending element to conduct current generated by the oscillatory motion of the piezoelectric bending element. In the ‘079 patent, the piezoelectric power generator is mounted within a water flow and is allowed to undulate in the presence of turbulent forces in the fluid stream.
In one embodiment of the ‘079 patent the flow induces a continuous sine wave shape in the elongated structure including spaced crests and troughs. 4, magnetic field layer 40 also has a mounting end 51 with mounting areas 52, shown as perforations that are joined by way of linkages 104A and 104B to a mount 100. In other embodiments, mounting areas 52 can be joined to linkages 104A and 104B in any other known manner including but not limited to adhesives and fasteners and in that regard a perforation may or may not be used.

FIG. 5 shows a top schematic view of one embodiment of a first layer 60 of electrical generator 20. Here first layer 60 has a support 62 with a first plurality of conductors shown here as conductors 64A and 64B positioned thereon.
