Prior art also describes wind powered Savonius type rotors. In this example, Magnus cylinders 200, 201, 210, and 211 are each mounted on a respective central axis 205 between the main shaft 40 and channel side walls 8, 9, 10 and 11. They will rotate around the main shaft in a clockwise or counterclockwise direction 20, as well as rotate around their central axis 205 as shown in 22. The walls can also be replaced with a tube 307 as shown in FIG. The fin device has the additional advantage that if mounted near the fluid intake for the system; the fin device will induce turbulence in the incoming fluid, which in turn will interact more favorably with the various Magnus cylinders as they rotate through the fluid in the second direction. This will cause the least one Magnus cylinder to rotate about this central shaft in a manner somewhat like that of a windmill, and the cylinder will travel in a circular arc in a direction that is substantially perpendicular to the direction of the moving fluid.
Thus the present invention extracts more energy from the moving wind or fluid than was previously possible. Thus it would be desirable to produce energy harvesters that are capable of achieving higher efficiency by higher speed Magnus cylinder rotation, as well as other efficiency improvements, but which do not require the need to reduce the operating efficiency of the system by using valuable generated electrical power just to rotate the Magnus cylinders. By contrast, the prior art motor driven designs did not increase the turbulence of fluid flow 90, and thus did not exhibit this effect. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of the appended claims. The present invention is not limited with regard to the number of cylinder pairs, or the type of fan devices used to rotate the cylinders or that can be installed, however, as any number of cylinder pairs can be installed to generate the desired torque.

As previously discussed, used of such shaped or curve chamber walls for flow intensification purposes may be used in any of the embodiments envisioned by the present invention. The cylinders are oriented transversely to the flow through the passage and are mounted for rotation, for example, via bearings 1080 and 1085 in cylinder supports 1000 and 1105 shown in FIG. The Magnus cylinders are typically mounted inside a channel formed by a passage defined by the opposed channel side walls, an optional bottom chamber wall, the inflow fluid channel walls, and the outflow fluid channel walls. 9 is shown mounted to a structure where the energy harvester is in communication with a fluid flow 90. The energy harvester is comprised of side walls 307 that receive a flow 90. The central shaft 40 with Magnus cylinders 200, 201, 210, and 211 located thereon is mounted between the channel side walls 307. The fluid flow path is defined by an inflow fluid channel formed by channel walls 307. The fin device 88 is located on Magnus cylinder drive shaft 45, and as before is rotated by fluid flow 90. Dolor muscular gemelos . As previously described, the fin means increase the turbulence of the fluid, thereby reducing the drag of the Magnus cylinders.
Magnus cylinders are downstream of other upstream Magnus cylinders.
FIG. 6 is a schematic representation of a double concentric shaft used to drive the Magnus cylinders and transmit the power to the generator. FIG. 5 is a schematic end representation of a radial device with staggered rotating Magnus cylinders in an axial position within a tube. 9. To increase the Magnus force lift, the energy harvester is replicated within 1 – 20 diameters of the Magnus cylinder. FIG. Dolor de brazo derecho y espalda . 12 is a schematic side representation of a radial device with double planar rotating Magnus cylinders in an axial position within a tube. Magnus cylinders are downstream of other upstream Magnus cylinders. Magnus rotating cylinders are attached to the outer shaft, often in a radial fashion.
These fin devices are in turn attached to a central drive shaft that is rotatably in communication with the various Magnus cylinder components of the energy harvester device. This central shaft itself will have its own axis of rotation that is substantially parallel to the direction of the fluid. 1045, which in turn drives the central axes 1205 and 1215, thereby causing Magnus cylinders 1200 and 1210 to rotate.

For example, Magnus type power generators. An energy harvester for use in fluid flows according to the present invention is shown in FIGS. In any application, the fluid flows can be the output flow streams of an effluent system. Channeling the flow from a larger cross section into a smaller cross section where the cylinder can take advantage of the increased flow speed of the fluid facilitates an increase in the lift of the cylinder. Since the energy harvester is located in the water, the lift is converted into mechanical energy to drive the generator. FIG. 18 is a schematic representation of an energy harvester using a gear train and drive shaft system. FIG. 16 is a schematic representation of an energy harvester of the invention attached to a bridge structure. FIG. 19 is a schematic representation of an energy harvester incorporating a pinion gear to drive a generator. Here the energy harvester chamber may be in the shape of a pipe 307. This design makes the device well suited for in-pipe operation.
For example, referring to FIG. For still higher efficiency, often at least some of these Magnus cylinders may additionally be positioned on different locations on the outer cylinder (e.g. In another embodiment of the invention the fin that drives the Magnus cylinder rotation shafts may co-exist with a secondary driving motor that can also rotate the Magnus cylinders.

Based upon this insight, the invention then defines the problem to be solved is to devise specific methods to increase the power generation of the Magnus device by utilizing the motion of the moving fluid (air or water) to increase the rotational speed of the Magnus cylinders to a rotational velocity that at the circumference of the cylinder can be in excess of the speed of the moving fluid itself. The invention is based, in part, upon the realization that higher efficiency Magnus force based energy harvesters can be produced by devising methods to better harness the force of the moving fluid to rotate the Magnus cylinder components of the energy harvesters at higher speeds.
Surprisingly, it has been found that an additional advantage of using fin device 88 is that fin device 88 acts to increase the turbulence of fluid flow 90 when located at the proximal end of the Magnus cylinder drive shaft 1045 when viewed from the fluid flow 90 perspective. In addition of avoiding the patristic loss of generated electrical energy that must be diverted to the Magnus drive motor, the fan device increases the turbulence of the fluid flow past the rotating Magnus cylinders, which reduces fluid drag on the Magnus cylinders. The output power increase as the rotational speed of the Magnus cylinder decrease due to reduction in head lost from the fin device need to rotate the Magnus cylinders at higher speeds. By contrast, alternative turbine designs, such as propeller type designs, can provide high power generation capability, at least in higher wind speed situations, but such propeller designs often operate with low efficiency when wind speed is low.

This decrease in drag and increase in speed of rotation is beneficial to the generation of electrical energy, which generally operates at higher efficiency as the size of the electrical generator and the rotation speed of the generator increase. This further increases overall energy harvester efficiency. This increases the efficiency of power production over prior art devices. In one preferred embodiment of the invention, the fluid flow is used to separately rotate one or more different types of fin devices. As before, the chamber walls can be curved (either in the side or bottom walls in this configuration) and can have opposite elevations in the plane parallel to the fluid flow path.

The present invention relates to wind and water powered energy harvesters, in particular Magnus type power generators. When the flow 90 is concentrated through the channel 95 and past the cylinders 1200 andl210, the Magnus cylinder rotation will produce a Magnus force lift. As before, in any embodiment, the fluid flow 520 (FIG. FIG. 23 shows a typical fin means in the form of a screw/auger. Here the term “fin” is used broadly to encompass a turbine or turbine blade, Savonius turbine, screw, or fan assembly. This lift then causes the outer shaft 1040 to rotate which in turn drives the drive pulley 1015 to drive generator drive pulley 1031 (via belt 1032) to drive the generator 1030. A pinion gear 1029 or bull gear 1028 may be used to drive the generator 1030 as shown in FIG. In this example, a supplemental Magnus cylinder rotation motor 1005 is connected to pulley 1010. A belt 1021 transmits torque from pulley 1010 to pulley 1020 to drive shaft 1045 supported in bearings 1085 and 1080. The belt, 1021 may be any type of force transmitting belt, including v-belts, ribbed belts, cogged belts, roller chain, and cables.
