One cycle of operation is defined here as the travel of a single wave from outset through transition to the point where this wave takes the position formerly occupied at outset by the next downstream wave. The sum of the lengths of the sides of the dodecahedron remains substantially the same at any point during the cycle of operation because the overall diameter of the dodecahedral tube 30 does not change during operation. During operation, the size of each plate 32 a remains constant, thereby necessitating a slight stretching and shrinking of the width of the fronds 2 with the rotation of the plates 32 a.

FIG. 9 illustrates internal details of the arrangement relative to each other, of the rigid rings 14 and rigid projections 15 of the ratcheted asterisk embodiment above, as illustrate in FIGS. A further distinction can be made between embodiments of the first group with tubes comprised of fronds, and embodiments of the second group with no fronds. The embodiments in the first group all utilize a single ribbon or a plurality of ribbons, said ribbons being made of a flexible or elastic sheet of material as described above. A first force 37 c is applied adjacent to the central axis of the hexagonal tubes so as to create undulations as described above and illustrated in FIGS. Each frond 2 is mechanically coupled to two other fronds through a flexible band 80 and crenated strips 3 such that the fronds 2, flexible bands 80 and crenated strips 3 form a tube that in cross-section forms a hexagon or dodecahedron, depending on the position of the cross-section within the cycle of operation as shown in FIGS.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS Embodiments of the present invention provide undulating mechanisms for generating electricity from a moving stream of fluid in two ways, the first is by utilizing materials that exhibit an electrical response to material strain, the second is by mechanically coupling the undulating motions of the mechanisms to an electromagnetic dynamo, or other output device. This invention embodies a range of mechanisms that share common principles for the creation of scalable hydroelectric generators, employing these novel materials and designed to anticipate the utilization of novel materials yet to be discovered or invented.

The hollow tubes 47 also serve as a principle conduit for electrical wiring associated with the transfer of harnessed electricity. As the wave undulations move along the material in the direction of the moving fluid, stresses also move through the material in the direction of the moving fluid, and electrical energy is generated from these stresses in the material. The fronds are connected to the crenated strips 3 which are connect continuously along the inside corners of the outer-casing 22 via a hinged or flexible connection 25. Each frond 2 is also connected continuously along both edges via flexible bands 80 to the fronds 2 on either side of it. The junctions of two adjacent fronds and the sixth restraining component, via flexible strips 3 and flexible bands 80, form a triangular tube 22 a which takes the form of a triangle in cross section. The “cells” of the honeycomb are dodecahedral tubes 30 having six sides which are fronds 2, and another six sides which are flexible or elastic strips 31. Each frond 2 is mechanically coupled to flexible or elastic strips 31 along the length of both edges of the frond 2. A plurality of dodecahedral tubes 30 aligned parallel to each other, and laterally connected to each other, comprise the dodecahedral honeycomb.

Young bearded man focuses down, has neck pain, massages and touches with hand The principles illustrated in this diagram are common to all embodiments of the present invention in which deflection of the material is converted into mechanical energy, which is mechanically coupled to an electromagnetic dynamo or other output device. Puntos de dolor en la espalda . As a series of wave undulations move along the tube, a corresponding series of strains in the material move along the tube, which are converted from mechanical strain within the material into electrical energy, when utilizing an appropriate material exhibiting an electrical response to mechanical strain within that material. An additional advantage that the present invention has over the Piezoelectric Eel, with its reliance on vortices in the moving fluid, is scalability because there, are in principle, no upward limits on the dimensions to which embodiments of the present invention can be built. In other instances, well-known structures, materials, or operations are not specifically shown or described in detail to avoid obscuring aspects of embodiments of the present invention.

Whereas in the first group the frond 2 is a component in all embodiments of the group, there are no fronds in this second group. The energy state of the frond 2 and the two crenated strips 3 is in equilibrium, as the internal energy of the first crenated strip 3 causes the first strip to “want” to straighten-out in one direction, but the internal energy state of the second crenated strip 3 causes this second strip to “want” to straighten-out in the opposite direction. The second way that energy is harnessed by the mechanisms embodied in the present invention is by coupling the mechanical action of the traveling undulating motions of the material as described above to a shaft or axle. FIGS. 12A-B illustrate an alternative mechanical coupling of the fronds 2 in the asterisk, in accordance with another embodiment of the present invention.

The inner edges of the three fronds 2 are not coupled to crenated strips 3 along their longitudinal edges but to each other via flexible bands 80. This mechanical coupling of the inner longitudinal edges of the fronds 2 forms a triangular cross-section, whose sides are comprised of three flexible bands 80. The polygonal cross-section can be closed by a plurality of elastic plates 18, stacked along the longitudinal axis, with planes parallel to each other and each plate connecting at its corners to the three fronds 2. As the waves move down the fronds 2, the polygonal cross-section and the elastic plates 18 rotate clockwise and counterclockwise about the longitudinal axis.

The wave undulations of each Type C hexagonal tube 49 are out-of-phase with the wave undulations of the four closest adjacent Type C hexagonal tubes 49, being separated from these adjacent Type C hexagonal tubes 49 by Type D hexagonal tubes 50 and Type E hexagonal tubes 51, as shown in FIG. The geometry of the first strip 74 has an inner edge 74 a and an outer edge 74 b formed by two arcs with a common center, such that the outer edge 74 b has a greater radius and a proportionally greater arc length than the inner edge 74 a.
