For steady winds with little variation, the opportunity for recovering extra energy from that variation is low. FIG. 12 is a flow chart of a method for identifying a site for recovering variational wind energy in accordance with the present disclosure. This finding, that for two different distributions, a given TI results in the same energy recovery from variation, is of significant interest and utility in predicting the available recoverable wind energy due to wind velocity variation at a particular site. 18 may be derived and used as a general curve for any wind distribution for VWER site predictive purposes. Vortices are caused by the presence of the building, and the apparatus is mounted on the building and positioned to receive the variable velocity wind caused by the building. The apparatus may be comprised of a wind receiving member 110 supported within a structural frame 40. In one embodiment, the wind receiving member 110 may be an elastic member, and may be suspended by a plurality of linear actuators 42, which may be operated so as to stretch the wind receiving member 110. In another embodiment, the wind receiving member 110 may be provided in a roll 112, such that certain linear actuators 44 connected to an opposed edge 114 may be operated to unroll the wind receiving member 110 in a “window shade” like manner.

In this embodiment, using a lever enables a standard coil winding such as that used in a generator to be implemented. The apparatus with the above electromagnetic generator may be further comprised of a first voltage gate in electrical communication with the first end of the coil of electrical conductor and with a first terminal of a first battery, and a second voltage gate in electrical communication with the first end of the coil of electrical conductor and with a first terminal of a second battery, such that motion of the magnet in the first direction causes the first battery to store electrical energy, and motion of the magnet in the second direction causes the second battery to store electrical energy. In that manner, when the web 108 of material is buffeted by a variable velocity wind, the magnet 316 remains stationary with respect to the structural frame member 24 or the web 108 of material to which it is joined, while the coil spring 210 surrounding the stationary magnet 316 undergoes expansion and contraction relative to the magnet 316 as indicated by bidirectional arrows 95, thereby generating electrical energy.
The magnetic rod 304 is movable within the wound conductor coil 306. In such a configuration, when the wind receiving member 102 is displaced by variable wind, the magnet 304 is displaced within the coil 306, thereby inductively generating electrical energy. Hence, both modern and historical methods of wind energy recovery have foregone the recovery of the energy contained within rapid, wind energy variation: variation due either to near-ground medium and high frequency velocity fluctuations, or, rapid density variations that might occur near, for example, the region of intersection of a large body of water and a land mass. In other embodiments, combinations of direction, surface area, shape, and mass may be varied to obtain optimum energy conversion by the apparatus. In certain embodiments, the mass of the wind receiving member may be made variable in response to the variable velocity of the wind. 116. Dolor de rodilla derecha significado . The wind vortices may be shed from alternating sides of the wind obstruction object as indicated schematically by wavy arrows 92. In certain embodiments, the wind obstruction object 122 may be mounted on a fixture (not shown) and made rotatable around a central axis 91. The object 122 may be further comprised of first and second wind anemometer cups 124 and 126 that are joined to opposed sides of the object 122. Thus when wind impinges upon the object 122, the onset of an instability will occur, slightly rotating the object, such that one of the cups 124 or 126 undergoes greater wind drag than the other.

In data acquisition of temperature, for example, an estimate of the maximum sampling rate is made based on knowledge of the process response time needed, the instrument response time, and other considerations. Other wind receiving members as described herein may also be suitable. The wind receiving member 108 is supported between structural members 26 and 28, which are in turn supported by arms 30 and 32. The arms 30 and 32 are joined to rotary bearings 34 and 36, which are joined to support member 20. A rudder 38 is joined to structural member 28, such that when a wind as indicated by arrow 99 and signal 98 is impinging upon the apparatus 16, the wind applies a drag force on the rudder 38. This drag force causes the apparatus 16 to rotate on support 20, thereby adjusting the angular position of the apparatus 16 so that the wind receiving member 108 is maintained substantially perpendicular to the direction of wind, regardless of any change in direction of the wind.

In such circumstances, the apparatus may include a vortex-causing device configured to increase the velocity variations of the wind impinging upon the first wind receiving member. Hence, the additional energy available from the rapid fluctuations in the wind velocity is about 4 percent, based on the TI specified as 0.2. It is noted that for large bladed wind energy harvesting devices, such as rotary wind turbines, this additional available energy is not harvested. Dolor en el dedo pulgar de la mano . The Applicants have conceived such an implementation in the context of unaffected mean velocity capture, thereby improving the overall energy capture from wind with added variation. The Applicants’ VWER apparatus and methods have a broad range of uses.
In certain embodiments, the elastic member may have a force constant that is variable. In one embodiment of the present method, time series simulated winds at progressively increasing variation amplitude at a single constant velocity were created with both uniform distribution and Weibull distribution. 2. It has been determined that the VWER curve is the same for wind-for both uniform velocity distribution wind and the Weibull wind simulation. 1 (Weibull parameters determining shape), the above data from step 2 are used to create the input/output Weibull distribution based on random input. 3. In general, to get approximately an additional 5% extra energy recovery, over and above a classical bladed system capturing a steady wind, a Turbulence Index of greater than 0.25 is required. 2) are not required. Additionally, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations therefore, is not intended to limit the claimed processes to any order except as may be specified in the claims.

Dolor muscular costillas . In certain embodiments, the first and second electrical energy may be converted to a third electrical energy having an AC voltage form compatible with an electrical power transmission grid, with the method further comprising delivering the third electrical energy to the electrical power transmission grid. Having developed a wind time series creation simulator for two probability density functions, it is now possible to predict, from simulation, the maximum energy recovery available in wind variation relative to the steady wind component.
