According to the present invention, an improved Magnus type wind (or fluid) power generator is described that harnesses the power provided by the moving fluid to spin the Magnus cylinders at high rotational speeds. The present invention uses fin or finned device (e.g. 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. This outer shaft will then often will be in communication with an electricity generator, and the captured energy will then be harnessed to perform useful work. In addition to generating work energy and electrical power, the system may also be used to provide stored chemical energy. However, if the fluid flow is otherwise constant, in order to increase the amount of generated electrical power, a greater Magnus force (lift) is needed, and to achieve this greater Magnus lift, it is necessary to use the electric motors to increase the rotational speed of the rotary cylinders still further.
In this embodiment, for higher efficiency, the fin and the gearing mechanism will be designed to causes the circumference of at least some, and preferably all of the Magnus cylinder(s) to move at a radial velocity that substantially greater than the speed of the fluid. To provide greater power generation efficiency through greater Magnus force or lift provided by faster rotating Magnus cylinders, co-pending application US Pat.

FIG. 9 shows the general principles of how a rotating Magnus cylinder generates Magnus lifting force. FIG. 17 is a schematic representation of an energy harvester of the invention attached to the bottom of the fluid channel by a bridge structure. 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. FIG. 2 is a schematic end view representation of a radial device with staggered rotating Magnus cylinders in an axial position within a channel defined by 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. Sangre en la orina y dolor de espalda . 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. As previously described, the fin means increase the turbulence of the fluid, thereby reducing the drag of the Magnus cylinders.
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 increase in turbulence reduces the drag of the Magnus cylinder movement in the fluid flow thereby increasing the energy that can be extracted. This Magnus cylinder positioning allows the fluid to be accelerated down the longitudinal length of the machine, and be further accelerated by each downstream cylinder, thereby increasing the torque created by the lift of each Magnus cylinder, which in turn translates into increased torque in the second direction, and more energy to drive generators and other useful devices. As the fluid flows past successive Magnus cylinders, the fluid flow is further accelerated by each prior Magnus cylinder, and this in turn increases the lift for successively positioned Magnus cylinder in the fluid flow path.
This further increases overall energy harvester efficiency. This Magnus force or lift can be used, for example, to rotate a horizontal rotary shaft, which in turn can be harnessed to do useful work, such as electrical power generation. The Magnus cylinders may be rotated by a drive mechanism as shown in FIG 6. As a result of fluid flow 90, the fin device 88 drives shaft 1045, which in turn drives the bevel gears 1050, 1055, 1060 and 1065 as previously discussed. By contrast, the prior art motor driven designs did not increase the turbulence of fluid flow 90, and thus did not exhibit this effect. Magnus forces used the rotating cylinders in a fluid environment where the axis of rotation of the cylinder was horizontal, and the fluid movement was also horizontal but generally perpendicular to the axis of rotation of the cylinder, the resulting force direction was often in a vertical or “up” direction, and thus the term Magnus “lift” is often used to refer to this Magnus force, even when the actual direction of the force is not always in an upward direction.

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. 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. As a result, using prior art designs, it was essentially impossible to increase the rotational speed of the Magnus force providing rotary cylinders beyond the speed of the wind that is powering the system.
Application 12/691,951, the disclosures of which are incorporated herein by reference, taught a Magnus type power generator that included a horizontal rotary shaft that transmits a rotation torque to a power generating mechanism, rotary cylinders that were disposed radially from this horizontal rotary shaft and located distally along the shaft, and a drive mechanism that was in communication with both the rotary cylinders and a driving motor. 1, 2 and 3. Here the energy harvester is mounted to a structure where the energy harvester is in communication with a fluid flow 90. Dolor en las articulaciones de los tobillos . As shown in Figure 7 and 8 the power produced is higher when fined device is utilized to drive the Magnus cylinders.

RPM with and without a motor for a flow of 4 feet per second for a machine schematically shown in FIG. FIG. 6 is a schematic representation of a double concentric shaft used to drive the Magnus cylinders and transmit the power to the generator. The fin device often will be attached to the inner (driving) shaft of the double shaft design, and will often rotate due to the force of fluid flow past the fin device.
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. Magnus cylinders at higher rotational speeds, including speeds in excess of the wind or fluid velocity, thus overcoming the prior art problems associated with Savonius rotors, while at the same time avoiding the higher expense, lower reliability, and electrical power consumption problems associated with the use of electrical motor Magnus cylinder rotation methods.

Prior art also describes wind powered Savonius type rotors. Prior art on such Magnus type power generation methods and devices includes U.S. A particular advantage of the current invention’s radial mounted Magnus cylinder design is that this type of design is very scalable. 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 device will make use of suitable gearing or other force transuding mechanisms to translate the motion of this central shaft into the rotary motion of the various (at least one) Magnus cylinder(s) about their respective first axes.
Thus in one embodiment, the invention may be an energy harvester device comprising at least one Magnus cylinder with a first axis of rotation and a circumference. Often this mechanism may be at least one electrical generator that in turn will produce electrical current and electrical power. This central shaft itself will have its own axis of rotation that is substantially parallel to the direction of the fluid. This central shaft may have an axis of rotation, as well as a substantially cylindrical interior that also has a second inner shaft positioned inside the central shaft, and this inner shaft will be capable of rotating independently about the central shaft’ s axis of rotation. The rotating inner shaft can then communicate rotational energy to the various Magnus cylinders (in the first direction), often through a gear arrangement. The as previously discussed, fluid flow 90 can be hydraulic or pneumatic (air or gas).

Although, Savonius turbines have previously been used as effective fluid (e.g. To increase the torque caused by the Magnus force lift, multiple Magnus cylinders may be used. Here the term “fin” is used broadly to encompass a turbine or turbine blade, Savonius turbine, screw, or fan assembly. The driving motor drives the Magnus force rotary cylinders around their respective axes, and the Magnus lift generated by interactions between the Magnus force rotary cylinders and the fluid flowing past the cylinders is used to rotate the horizontal rotary shaft, which in turn drives the power generating mechanism. As in other embodiments, the energy harvester may be connected to a suitable electric generator, which may be mounted on the vessel in a water tight chamber or which may be remotely located.
