Drag forces resulting from the wind blowing over a generally blunt object result forces that push cylinder 100 in a direction with the wind. The purpose of the rotation is to create an incidence of the Magnus effect as air passes over the cylinder. Power generators 18 are incorporated into the cylinder mounting structures and comprise electrical generators, preferably in the form of magnets and conductor windings. Power generators 18 are preferably incorporated into the cylinder mounting structures and configured to harness movements of the cylinder to generate electrical current. 4 which shows a free-body-diagram of a cross section of the rotating cylinder. FIG. 6 shows yet another embodiment of the present invention installed upon a sloped roof. FIG. 2 illustrates the effects of heavy winds on a building with a slightly pitched roof.

Another embodiment of the present invention is shown in FIG. 1, a building 10 with a flat roof 11 is shown. 5. As shown in FIG. In addition, vertical support 304 is slidably mounted within horizontal track 306 and adapted to generate electrical energy from movement of vertical support 304 relative to track 306. Dolor de cintura lado derecho y pierna . The relative movement of vertical support 304 relative to track 306 may be harnessed by a fore and aft cables wound about a spool as illustrated in FIG. 5 is the installation of an aeolian power generator 18 into the arms of the brackets which hold the cylinder 10. This gives the cylinder 10 and a portion of the cylinder mount a certain degree of freedom to oscillate vertically within the mount. A heat transfer coil 410 is housed within supporting structure 404 in thermal communication with thermoelectric generator 406 and disposed in the airflow path of air entering an air inlet 412 defined by structure 404. Each cylinder 402 is preferably adapted with a fan blade 405 to move air through the cylinder for reasons more fully described herein.

The force of the wind 30 projected onto the spinning cylinder 10 creates downward force, illustrated by reference number 34 that is generally perpendicular to the direction of the airflow. Furthermore, there exists a need for a wind mitigating device that can be retrofitted onto a building and need not be installed while the structure is being built. Therefore, the present invention may be installed at the highest point of a roof or any other point thereon. Accordingly, there exists the need for new and useful devices and systems for mitigating the uplift effect caused by wind forces on a roof. In view of the wind mitigation systems in existence at the time of the present invention, it was not obvious to those persons of ordinary skill in the pertinent art as to how the identified needs could be fulfilled in an advantageous manner. Accordingly, it is an object of this invention to provide a wind mitigation device and system which reduces the upward forces on a rooftop that are created by strong winds.

It is also an object of this invention to provide a wind mitigation device that harnesses the winds power to produce electricity. For example, wind turbine 202 may operate in wind power mode to generate electricity and convert, upon deployment of sheet material 206, into Magnus effect operating mode in response to high wind speeds.
This phenomenon is referred to as the suction effect and it is induced directly by the vortices 32. The suction effect is the primary mode of failure of roof tops during storms with heavy winds. Many of these repairs involve damage to roofs or roof replacement entirely. The upwardly pulling suction force becomes very powerful in high winds and is often powerful enough to break away a roof entirely from the rest of the house. 5, the cylinder 10 is horizontally supported in vertically spaced relation with the roof. Alternate embodiments further function to generate electrical power from movement and/or oscillations of the Magnus cylinder structures thereby producing environmentally friendly electrical energy without presenting a hazard to wildlife, such as birds.

The electrical power generation capability of the system may be enhanced by covering the external surface of cylinders 402 with flexible solar panels which capture and convert solar energy to electrical energy. As should be apparent, the temperature differential is maximized with structures having dark roofs. As should be apparent, the downward force may be applied to the roof structure via any suitable load transferring structure. Thermal conductors 408 conduct heat from the roof to thermoelectric generator 406. Thermal conductors may comprise metal bars having a high thermal conductivity, or may comprise more complex heat transfer devices. The cables unwinding causing the cylinders to spin can in turn power a small generator from the revolutions of the cylinders.. Dolor planta del pie despues de correr
