Man feels strong headache and looks tired In this arbitrary starting position, the upstream support member is oriented substantially parallel to the direction of fluid flow. At the least, the force transfer mechanism 500 has a first end 512 and a second end 514, with the first end 512 in connection with at least one of the foil 100, the upstream support member 200, and the downstream support member 300. The second end 514 of the force transfer mechanism 500 is in connection with the machine doing useful work. Other devices using reciprocating movement of a foil either require an external mechanism to reorient the foil to allow for movement in the opposite direction, such as a motor or an actuator, or require the foil to strike a surface, with the impact reorienting the foil. 2D and 2I. It is the relationship of the upstream support member 200 and the downstream support member 300 to the foil 100 that causes the foil 100 to “tip” in the correct direction to cause the correct lateral movement 80. The movement 80 of the foil 100 towards and then into a neutral position, the subsequent “tipping” of the foil 100 out of the neutral position, and the ensuing movement 80 of the foil 100 towards and then into the other neutral position represents the reciprocating movement defining the device 10. None of this reciprocation requires a force other than the fluid flow 20 to act on the foil 100, nor does it require the foil 100 to rebound off any object in order to reorient itself.

The foil 100 may also be configured symmetrically, whereby its profile at its leading edge 112 is substantially the same as its profile at its trailing edge 114. Such a configuration is appropriate where the fluid flow 20 is bidirectional, for example, ocean 50 tidal currents. 4. Each of the plurality of foils 100 is configured as described above. Dolor de espalda y debilidad en las piernas . In another embodiment of the invention, where the fluid medium is water, the foil 100 may be buoyant. When the foil is angled relative to the direction of fluid flow (the “angle of attack”), the component of the fluid passing over the surface of the foil angled away from the direction of fluid flow moves faster than the component of the fluid passing over the surface of the foil angled towards the direction of fluid flow. In order for the device 10 to work properly, each of the lengths of the upstream support member 200, the foil 100, and the downstream support member 300 must be fixed, and combined must be greater than the distance from the upstream connection point 422 of the frame 400 to the downstream connection point 424 of the frame 400 along the frame axis.

The foil has a leading edge and a trailing edge. See FIG. 2E. This represents the furthest rightward extent of the trailing edge of the foil-it cannot move any further to the right nor any further downstream. FIG. 6A is a top plan view of an embodiment of the foil, the upstream support member, the downstream support member, and the pivots. 1 is a schematic plan top view of one embodiment of the invention. In one embodiment of the present invention energy transfer occurs by using the lifting force. Energy transfer occurs either by drag when the foil and the fluid are moving in the same direction or by lift when the foil moves perpendicularly across the flow of moving fluid.

In the absence of lift forces when the angle of attack is zero, only drag forces act on the foil, moving the foil in a downstream direction. Drag/drift forces parallel to the fluid flow now act on the foil, biasing it in a downstream direction. The frame 400 has an upstream connection point 422 located on the upstream portion 412 of the frame 400, and a downstream connection point 424 located on the downstream portion 414 of the frame 400. The upstream connection point 422 of the frame 400 is in pivotal connection with the frame connection point 222 of the upstream support member 200. In one embodiment the upstream pivot 612 is interposed between the upstream connection point 422 of the frame 400 and the frame connection point 222 of the upstream support member 200. The downstream connection point 424 of the frame 400 is in pivotal connection with the frame connection point 322 of the downstream support member 300. In one embodiment the downstream pivot 614 is interposed between the downstream connection point 424 of the frame 400 and the frame connection point 322 of the downstream support member 300. The frame 400 has a frame axis running from the upstream connection point 422 of the frame 400 to the downstream connection point 424 of the frame 400 in a direction substantially parallel to the direction of the fluid flow 20. One configuration of the device 10 disclosing the foil 100, the upstream support member 200, the downstream support member 300, and the frame 400 is shown in FIG.
