     General Overview 
     In accordance with some embodiments of the present disclosure, a portable system for converting wind energy into electrical energy is disclosed. In accordance with some embodiments, the disclosed system may include a frame hosting one or more conversion modules, arranged as desired. A given conversion module may include one or more wind energy conversion devices (WECDs), arranged as desired. In accordance with some embodiments, the conversion modules may be electrically connected, directly or indirectly, with one or more downstream electrical energy storage elements (e.g., such as a battery or other capacitive element, optionally native to a host platform). In this manner, the disclosed system may be configured, in accordance with some embodiments, for use in storing and/or supplying electric power for downstream consumption by a host platform or otherwise.

In accordance with some embodiments, the disclosed system may be configured, in a general sense, as including a farm-like network layout of micro wind energy-conversion devices (e.g., of a few millimeters in size) on a small board configured to generate cumulative electrical energy from moving air. In some cases, the disclosed system optionally may include one or more photovoltaic devices (e.g., solar power modules or elements), thereby permitting the system to generate energy from both wind and sunlight, separately or concurrently. 
     Generally, the disclosed system may be scaled up or down in size and energy production, as desired for a given target application or end-use. In some embodiments, the disclosed system may be configured with a generally low-profile form factor, helping to reduce drag and lift problems which otherwise can occur with larger form factors on host platforms. In some embodiments, the disclosed system may be compatible with a large variety of mounting surfaces and orientations. In some embodiments, the disclosed system may be flexible and/or packable, making it more readily transportable and mountable with a given host platform. 
     In some instances, a system provided using the disclosed techniques can be configured, for example, as: (1) a partially/completely assembled unit including a frame and at least one conversion module; and/or (2) a kit or other collection of discrete components (e.g., frame, one or more conversion modules, etc.) which may be operatively coupled as desired. 
     System Architecture and Operation 
       FIG.  1    illustrates a wind energy conversion system  1000  configured in accordance with an embodiment of the present disclosure.  FIG.  2    illustrates a system  1000  configured in accordance with another embodiment of the present disclosure. As can be seen from these figures, system  1000  may include one or more conversion modules  100  hosted by a frame  103  of a given configuration. In addition, system  1000  may include one or more electrical energy storage elements  110  operatively coupled (directly or indirectly) with one or more conversion modules  100 . Each of these elements is discussed in turn below. 
     As discussed herein, system  1000  may be configured, in accordance with some embodiments, to produce electrical energy from harvested wind energy. To that end, system  1000  generally may be configured to convert the energy of wind movement into mechanical power, which in turn may be utilized in producing electricity. The electricity produced may be used immediately or stored for later use, as desired. 
     As previously noted, system  1000  may include one or more conversion modules  100 .  FIG.  3    illustrates a conversion module  100  configured in accordance with an embodiment of the present disclosure. As can be seen, conversion module  100  may include one or more wind energy conversion devices (WECDs)  102  hosted by a substrate  101 , each of which is discussed in turn below. 
     In accordance with some embodiments, a given WECD  102  may be (or otherwise may include) a device configured to convert wind energy into electrical energy. To such ends, a given WECD  102  may include, for example, a wind turbine generator element through which mechanical energy (e.g., harvested from air or other gas passing over and/or through such WECD  102 ) is converted into electrical energy. 
     The specific configuration of a given WECD  102  may be customized, as desired for a given target application or end-use. In accordance with some embodiments, a given WECD  102  may be configured (in part or in whole) like a horizontal axis wind turbine (HAWT), the blades or vanes of which may rotate along a horizontal axis (e.g., generally perpendicular to the direction of gravity), such as with a traditional (e.g., Dutch) windmill. In accordance with some embodiments, a given WECD  102  may be configured (in part or in whole) like a vertical axis wind turbine (VAWT), the blades or vanes of which may rotate along a vertical axis (e.g., generally parallel to the direction of gravity), such as with a Savonius or Darrieus (e.g., giromill) wind turbine. In accordance with some embodiments, a given WECD  102  may be configured (in part or in whole) like an anemometer, the cups or vanes of which may rotate along a horizontal or vertical axis, as desired. In accordance with some embodiments, a given WECD  102  may be configured such that the orientation of its blades, vanes, or cups is fixed and, thus, not reorientable (without damaging the WECD  102 ), at least with respect to wind direction. In accordance with some embodiments, a given WECD  102  may be configured such that the orientation of its blades, vanes, or cups is adjustable and, thus, reorientable (without damaging the WECD  102 ), at least with respect to wind direction. Other suitable configurations for a given WECD  102  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     The dimensions of a given WECD  102  may be customized, as desired for a given target application or end-use. In some cases, a given WECD  102  may be configured as a wind energy conversion microdevice. In some such cases, the size of a given WECD  102  may be on the order of millimeters. For example, a given WECD  102  may have a dimension (e.g., length, width, and/or height) in the range of about 500 mm or less (e.g., about 1-100 mm, about 100-200 mm, about 200-300 mm, about 300-400 mm, about 400-500 mm, or any other sub-range in the range of about 500 mm or less). In some cases, a given WECD  102  may have a dimension (e.g., length, width, and/or height) in the range of about 100 mm or less (e.g., about 1-10 mm, about 10-25 mm, about 25-50 mm, about 50-100 mm, or any other sub-range in the range of about 100 mm or less). In some cases, a given WECD  102  may have a dimension (e.g., length, width, and/or height) in the range of about 50 mm or less (e.g., about 1-25 mm, about 25-50 mm, about 10-40 mm, or any other sub-range in the range of about 50 mm or less). In some cases, a given WECD  102  may have a dimension (e.g., length, width, and/or height) in the range of about 10 mm or less (e.g., about 1-5 mm, about 5-10 mm, about 3-8 mm, or any other sub-range in the range of about 10 mm or less). In some other cases, the size of a given WECD  102  may be on the order of micrometers or nanometers or smaller still. Other suitable dimensional ranges for a given WECD  102  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     As previously noted, a given conversion module  100  may include a substrate  101  configured to host its one or more constituent WECDs  102 . Generally, substrate  101  may be of any suitable configuration, as will be apparent in light of this disclosure. In some cases, substrate  101  may be (or otherwise may include) a board, circuit board (e.g., printed circuit board, or PCB), plate, grid, or screen, to name a few options. In some cases, substrate  101  may be (or otherwise may include) a frame, housing, or enclosure, among other options. In some cases, substrate  101  may include any one (or combination) of walls, rails, legs, or arms, for instance. Moreover, the material construction of substrate  101  (in whole or in part) may be customized, as desired for a given target application or end-use. 
     The geometry and dimensions of a given substrate  101  (and, thus, of the associated conversion module  100  more generally) may be customized, as desired for a given target application or end-use. For example, in some cases, substrate  101  may be of generally polygonal geometry (e.g., a triangle, rectangle, square, parallelogram, rhombus, trapezoid, pentagon, hexagon, or other desired polygonal shape). In some cases, substrate  101  may be of generally curved geometry (e.g., a circle, ellipse, arc, semi-circle, semi-ellipse, closed-curve, open-curve, or other desired curved shape). In some cases, a first portion of substrate  101  may be of generally polygonal geometry, whereas a second portion thereof may be of generally curved geometry. In some cases, substrate  101  may have two or more walls, rails, legs, arms, or other perimetral boundaries which run substantially parallel, substantially perpendicular, or at an angle (e.g., acute angle, right angle, or obtuse angle) with respect to one another. Other suitable geometries and dimensions for substrate  101  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     For a given conversion module  100 , the constituent WECDs  102  thereof may be interfaced with substrate  101  using any of a wide range of suitable interfacing means. For instance, in some cases, a given WECD  102  may be interfaced with substrate  101  utilizing any one (or combination) of physical fitting (e.g., a friction fit, snap fit, or threaded/screw fit), mechanical fasteners (e.g., such as clamps, clips, brackets, wrapping, or rope/cord-like means), adhesive materials (e.g., such as a glue or epoxy), hook-and-loop fasteners (e.g., such as those produced by Velcro USA, Inc.), and magnetic materials, among other options. In some cases, a given WECD  102  may be interfaced with substrate  101  by partially or fully inserting or integrating such WECD  102  within such substrate  101 . In some cases, a given WECD  102  may be interfaced with substrate  101  via molding, encapsulation, or thermoforming. Other suitable means for interfacing a given WECD  102  with an associated substrate  101  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     The arrangement of WECDs  102  for a given conversion module  100  may be customized, as desired for a given target application or end-use. For instance, in some embodiments, WECDs  102  may be distributed, in part or in whole, as a regular array in which all (or some sub-set) of WECDs  102  are arranged in a systematic manner in relation to one another. In some embodiments, WECDs  102  may be distributed, in part or in whole, as an irregular array in which all (or some sub-set) of WECDs  102  are not arranged in a systematic manner in relation to one another. In some embodiments, WECDs  102  may be distributed, in part or in whole, as a semi-regular array in which a sub-set of WECDs  102  are arranged in a systematic manner in relation to one another over a given conversion module  100 , but at least one other WECD  102  is not so arranged. In some cases, WECDs  102  may be arranged in a linear, concentric, eccentric, geometric, or other arrangement, as desired. In some cases, the constituent WECDs  102  of a given conversion module  100  may be arranged uniformly, whereas in some other cases, the constituent WECDs  102  may be arranged non-uniformly. In some cases, the constituent WECDs  102  of a given conversion module  100  may be arranged in a matrix of row(s) and column(s). In some cases, the constituent WECDs  102  of a given conversion module  100  may be arranged in a two-dimensional (e.g., substantially planar) arrangement. In some cases, the constituent WECDs  102  of a given conversion module  100  may be arranged in a three-dimensional arrangement. In some cases, the constituent WECDs  102  of a given conversion module  100  may be staggered or offset from one another to a given degree. The quantity, density, and spacing between neighboring WECDs  102  of a given conversion module  100  may be customized, as desired for a given target application or end-use. 
     In accordance with some embodiments, a given conversion module  100  may include only a single type of WECD  102 ; that is, such a conversion module  100  may have a homogeneous plurality of constituent WECDs  102 . In accordance with some embodiments, a given conversion module  100  may include two or more different types of WECDs  102 ; that is, such a conversion module  100  may have a heterogeneous plurality of constituent WECDs  102 . Groupings of WECD  102  homogeneity and heterogeneity may be provided for a given conversion module  100 , in accordance with some embodiments. 
     As previously noted, system  1000  may include a frame  103  configured to host one or more conversion modules  100 . In accordance with some embodiments, frame  103  may be (or otherwise may include) a housing, enclosure, rack, bracket, or brace, to name a few options. In some cases, frame  103  may include any one (or combination) of walls, rails, legs, or arms, for instance. In some embodiments, frame  103  may be of monolithic construction, constituting a singular unitary piece, whereas in some other embodiments, frame  103  may be of polylithic construction, constituting separate pieces that may be coupled with one another (e.g., as an assembly) in a temporary or permanent manner. Assembly of a polylithic frame  103  may be provided via any one (or combination) of suitable means, including, for example, fastener(s), friction fit, mated engagement, threaded engagement, adhesive(s), and magnetic engagement, among other options. The material construction of frame  103  (in whole or in part) may be customized, as desired for a given target application or end-use. As will be appreciated in light of this disclosure, it may be desirable, at least in some instances, to ensure that frame  103  is configured to help keep environmental hazards (e.g., moisture, dust, etc.) away from hosted conversion module(s)  100 . 
     The geometry and dimensions of frame  103  may be customized, as desired for a given target application or end-use. In some cases, frame  103  may be of generally polygonal geometry (e.g., a triangle, rectangle, square, parallelogram, rhombus, trapezoid, pentagon, hexagon, or other desired polygonal shape). In some cases, frame  103  may be of generally curved geometry (e.g., a circle, ellipse, arc, semi-circle, semi-ellipse, closed-curve, open-curve, or other desired curved shape). In some cases, a first portion of frame  103  may be of generally polygonal geometry, whereas a second portion thereof may be of generally curved geometry. In some cases, frame  103  may have two or more walls, rails, legs, arms, or other perimetral boundaries which run substantially parallel, perpendicular, or at an angle (e.g., acute angle, right angle, or obtuse angle) with respect to one another. Other suitable geometries and dimensions for frame  103  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     In accordance with some embodiments, frame  103  may include one or more frame slots  104  configured to receive and retain one or more conversion modules  100  in a temporary or permanent manner, as desired. A given frame slot  104  may be configured, in accordance with some embodiments, to host a plurality of conversion modules  100  in a substantially linear (e.g., a row or column) format, with such conversion modules  100  being situated substantially adjacent one another (optionally with an intervening gap or space therebetween). In accordance with some embodiments, a given frame slot  104  additionally (or alternatively) may be configured to receive and retain one or more other types of energy conversion elements (e.g., one or more photovoltaic/solar panel modules or other elements) in a temporary or permanent manner, as desired. 
     The geometry and dimensions of a given frame slot  104  may be customized, as desired for a given target application or end-use. In some cases, a given frame slot  104  may be of generally polygonal geometry (e.g., a triangle, rectangle, square, parallelogram, rhombus, trapezoid, pentagon, hexagon, or other desired polygonal shape). In some cases, a given frame slot  104  may be of generally curved geometry (e.g., a circle, ellipse, arc, semi-circle, semi-ellipse, closed-curve, open-curve, or other desired curved shape). In some cases, a first portion of a given frame slot  104  may be of generally polygonal geometry, whereas a second portion thereof may be of generally curved geometry. In some cases, a given frame slot  104  may have two or more walls, rails, legs, arms, or other perimetral boundaries which run substantially parallel, substantially perpendicular, or at an angle (e.g., acute angle, right angle, or obtuse angle) with respect to one another. In some instances, a given frame slot  104  may have a geometry that is similar to the geometry of frame  103 ; for example, if frame  103  is of generally polygonal geometry (e.g., rectangular or square), a given frame slot  104  also may be of comparable polygonal geometry. In some instances, a given frame slot  104  may have a geometry that is dissimilar to the geometry of frame  103 ; for example, if frame  103  is of generally polygonal geometry (e.g., rectangular or square), a given frame slot  104  may be of generally curved (e.g., circular or elliptical) geometry. Also, as will appreciated in light of this disclosure, it may be desirable, at least in some instances, to provide a given frame slot  104  with a geometry that is readily compatible with that of the conversion module(s)  100  which it is to host. As will be further appreciated in light of this disclosure, numerous variations and combinations of geometries of frame  103 , its constituent frame slot(s)  104 , and hosted conversion module(s)  100  may be provided, as desired for a given target application or end-use. Other suitable geometries and dimensions for frame slot(s)  104  will depend on a given target application or end-use and will be apparent in light of this disclosure. 
     Conversion module(s)  100  may be interfaced with a given frame slot  104 , as desired. In some embodiments, a given frame slot  104  may be configured such that a given conversion module  100  may be inserted into it from a direction generally perpendicular to a plane of frame  103 . For instance, a conversion module  100  may be dropped or nested into a given frame slot  104  from above or beside frame  103 . In some embodiments, a given frame slot  104  may be configured such that a given conversion module  100  may be inserted into it from a direction generally parallel to a plane of frame  103 . For instance, a conversion module  100  may be slid into a given frame slot  104  from an edge or side of frame  103 . In some cases, a given frame slot  104  may be configured such that any given conversion module  100  hosted thereby may be removed/replaced without requiring movement or other disruption of other conversion module(s)  100  hosted by that same frame slot  104 . In some other cases, a given frame slot  104  may be configured such that a given conversion module  100  hosted thereby may be removed/replaced only by first moving or otherwise disrupting at least one other conversion module  100  hosted by that same frame slot  104 . 
     For a given frame slot  104 , conversion module(s)  100  may be interfaced therewith, in a temporary or permanent manner, using any of a wide range of suitable interfacing means. For instance, in some cases, a given conversion module  100  may be interfaced with a given frame slot  104  utilizing any one (or combination) of physical fitting (e.g., a friction fit, snap fit, or threaded/screw fit), mechanical fasteners (e.g., such as clamps, clips, brackets, wrapping, or rope/cord-like means), adhesive materials (e.g., such as a glue or epoxy), hook-and-loop fasteners (e.g., such as those produced by Velcro USA, Inc.), and magnetic materials, among other options. In some instances, a locking mechanism may be utilized to secure conversion module(s)  100  within a given frame slot  104 , for example, to prevent theft and/or accidental dislodging. In some cases, a given conversion module  100  may be interfaced with a host frame slot  104  by partially or fully inserting or integrating such conversion module  100  within such frame slot  104 . In some cases, a given conversion module  100  may be interfaced with a host frame slot  104  via molding, encapsulation, or thermoforming. Other suitable means for interfacing a given conversion module  100  with a given frame slot  104  will depend on a given target application or end-use and will be apparent in light of this disclosure.
