4 so that piston 74 a is maintained in one of its extended positions, e.g. The oscillating blade geometry of my machines is unique in this regard in that these desirable ratios are maintained over the whole length and surface of the blades and not merely at their tips, making every part of my blade structure equally productive. The main body 224 a is swingably supported within housing 220 by a vertical shaft 246 which may extend the length of the blade or by comparable upper and lower stub shafts. 19A and 19B, above a wind speed of 4 mps, the apparatus always operates within its desired speed range, i.e. Should any of my machines stall or slow down below synchronous speed in midcycle for any reason other than low wind speeds, the IMAG automatically becomes a motor and powers it back up to synchronous speed where the wind, if present, takes over.
6 and 7 is designed particularly for low pressure head applications, i.e. Thus, there is a need for a fluid responsive power generator and power generating method which can economically and safely extract useful power from relatively low head shallow waters and the more turbulent lower speed wind currents commonly found near major population centers and on flat terrain and to use that power to perform useful work such as the generation of electricity nearer the point of consumption, thereby saving the environmentally degradation as well as the capitol expense and losses of power transmission systems. 1 and 2 of the drawings which show my apparatus, indicated generally at 10, as adapted to extract useful power from a relatively low pressure head, open shallow water source such as a river or stream, low head being defined as less than 10 meters. BACKGROUND OF THE INVENTION This invention relates to power generation apparatus employing one or more blades which move under the influence of a fluid stream to produce an output force capable of performing useful work.

Thus, when the blades are near their TDC and BDC positions, they experience the same fluid flow regimes and forces described above for the invention embodiments that rely on hydropower, vis a vis cyclically blocking the free stream flow. 1 and 2 invention embodiment. Another object of the invention is to provide such apparatus which can utilize the energy in moving wind or water to produce shaft torque to generate electrical power without harming a significant portion of the bat, bird or fish populations that attempt to fly or swim thru them. Flap 184 is a bistable member which can be swung between two extreme positions by at least one toggling mechanism indicated generally at 186 located inside main body 180. The toggling mechanism 186 may be substantially identical to and operate in the same way as the one depicted in FIG. The vertical position of the follower is controlled by a cam 106 which may be rotated by a lever arm 108. Arm 108 may be progressively swung between a HIGH position wherein the cam follower 105 is opposite a low point of the cam 106 so that master cylinder pump 104 delivers little or no fluid to cylinder 98 in blade 20. Resultantly, actuator toggles flap 68 between its two maximum positions as described above.

15 and 16 to minimize drag and to extract the maximum amount of energy from the winds. As noted previously, for maximum power, the flow exit from housing 122 as well as the power converter 152 should be near the level of the water W on the downstream side of the dam D. Also for maximum efficiency, the draft tubes 134 should be designed to recover the siphon-velocity energy at the outlet end of housing 122 converting it into negative gage pressure down to the approximate vapor pressure of water. Thus, housing 122 has a pair of inlets 122 a which conduct water streams into housing channels 124 a and 124 b, and a pair of outlets 122 b through which these water streams leave the housing. 2. Closed Channel Embodiment My basic apparatus can also be used in closed channel, Micro-Hydro applications where water or other fluid is caused to flow through one or more pipes or penstocks.
