     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present disclosure is generally related to the extraction of electrical energy from hot gasses, primarily in the firearm industry. In addition, the present disclosure also 
     relates to a new type of portable electric generator that may be used in many similar or analogous applications. 
     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
     Typically batteries may be used to power electronic devices attached to or a part of firearms. Here, the battery provides the electric potential necessary to power these electronic devices using a chemical reaction. 
     In practice there are two kinds of batteries: disposable and rechargeable. In disposable batteries the chemical reaction that provides power irreversibly changes its reactants; when these reactants are used up, the battery stops producing electricity and is useless. 
     In rechargeable batteries the chemical reaction that provides power reversibly changes its reactants; when these reactants are used up and the battery stops producing power, in this case however, a current can be applied to the rechargeable battery to reform its reactants. Once the reactants are reformed the battery is again able to supply power. 
     All batteries, both disposable and rechargeable, are subject to self-discharge while not in use. This is due to the occurrence of inevitable side reactions. Self-discharge is particularly problematic for battery powered electronics that see only sporadic use like electronic firearms accessories. This is because a battery can lose its charge while not in use, becoming unable to provide power the next time a person tries to use it. 
     An alternative to batteries is the generation of electrical power locally using electrical generators attached to firearms. These generators seek to harness the kinetic energy of a firearm&#39;s projectile, the mechanical energy of automatic firearm operation, or the thermal energy imparted to components of a firearm during its normal operation. 
     In practice projectile based generators have undesirable hidden costs. Projectile based generators require the use of projectiles with magnetic properties (U.S. Pat. No. 3,257,905). Standard ammunition lacks these magnetic properties which means anyone wishing to use a projectile based generator must buy new, more expensive, ammunition. 
     Other projectile based generators seek to extract kinetic energy from projectiles by impeding their travel (U.S. Pat. No. 2,822,664). While this method does not necessitate specialized ammunition, it removes so much kinetic energy from the projectile that the firearm the generator is attached to can no longer serve as a gun. 
     Mechanically based generators, unlike projectile based generators, function with standard ammunition since they extract energy from the mechanical action of an automatic firearm (U.S. Pat. No. 7,525,203). In practices though these mechanically based generators can only function when installed on automatic firearms. This makes mechanically based generators useless for manually operated firearms. 
     Thermal based generators require no specialized ammunition, or a specific type of firearm. Thermal based generators draw energy from the heat radiated by parts of a firearm during its operation (U.S. Pat. Nos. 6,461,752; and 8,783,154). Typically thermal based generators use the barrel of a firearm as their source of heat. In practice this system operates at very low efficiency until the barrel heats up. Hot barrels affect the accuracy and physical integrity of a firearm. Additionally hot barrels are uncomfortable for the firearm operator that must be near and/or hold them. In practice a thermal based generator works against its user as it works only with a hot firearm, which is undesirable to its user. Additionally the efficiency of thermal based generators relies on a favorable ambient temperature, a factor outside of a user&#39;s control.

     SPECIFICATION 
     In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described. 
     Preferred embodiments of The Mark I have one Firearm Alternator. Various embodiments of The Mark I have one or more Firearm Alternators. 
     A preferred embodiment of the Firearm Alternator utilizes a heat exchanger of bronze mesh and an electric generator that is of a thermoelectric type. The Alternator includes a heat sink, insulating housing, one or more thermoelectric generators and an electric load. 
     In one or more preferred embodiments, the Alternator should not exceed 0.75 inches in the vertical when measuring from the central bore axis. This is consistent with a cylinder with a diameter of 1.5 inches. The Alternator should have a length between 6 to 7 inches. The Alternator should have be around 20 ounces give or take 3 ounces in total weight. 
     In one or more embodiments, there may be one or more alternators. 
     In one or more preferred embodiments, the heat sink will be composed of a stack of bronze thirty-mesh tin plated bronze disks. The disk will each have a central 0.234 inch diameter hole for the passage of a projectile. Each disk will have radial slit(s) cut into them to allow direct contact with a thermoelectric generator mounting. Disks will be stacked together to fill a cylindrical volume. 
     In one or more preferred embodiments, the thermoelectric generator will be mounted to an aluminum plate of equal size. The aluminum plate will have a central downward rectangular protrusion like a sailboat&#39;s keel. This protrusion (contact fin) will make physical contact with the mesh heat exchanger via the radial slits cut into the mesh disks. 
     In one or more preferred embodiments, the housing will internally house the mesh heat sink. Slits should be cut into the housing at thermoelectric generator mounting points to allow the contact fins to enter the housing&#39;s internal volume and touch the heat sink. The housing should thermally insulate the heat sink from the environment. 
     Should the device be deemed overweight when entirely filled with heatsink disks, the housing will have two chambers split by a solid dividing wall. The first chamber (nearest the rifle) is a sealed expansion chamber, the housing of which is lined with a protective mesh lining that acts as a heatsink. The second chamber is the heatsink chamber and is filled with the mesh heatsink disks. The expansion chamber serves to preserve internal volume without going overweight. Ideally there would be no expansion chamber and just a heatsink, weight restrictions may limit us however, requiring the addition of a mostly empty chamber. 
     In one or more preferred embodiments, connected to the thermoelectric generator is an ultra capacitor or battery. Since the firearm to which a firearm alternator is attached cannot be relied on to fire continuously a battery or ultra-capacitor will store the bursts of energy. 
     Upon the discharge of the firearm to which the firearm alternator is attached, a projectile passes from the muzzle of the firearm into the firearm alternator. Behind the projectile follows the gaseous discharge of the firearm. The projectile passes safely through the central hole of the mesh disks that make up the heatsink. The gaseous discharge behind the projectile expands into the volume occupied by mesh disks, radiating heat into the mesh. The heat in the mesh radiates into the aluminum projections of thermoelectric generator mountings, heating the thermoelectric generator. The thermoelectric generator then uses the heat gradient to generate electricity. The electricity is then stored in either a battery or an ultra-capacitor which can be discharged to power an electronic device like an LED or rifle sight. 
     An example of bronze mesh for use as a heat exchanger in embodiments of the Mark I Firearm Alternator is 30 Mesh Bronze 0.012 sold by TWP, Inc. 2831 Tenth St., Berkeley, Calif., 94710 (part number 030X030PC0120W36T DK). 
     An example of a thermoelectric generator for use in embodiments of the Mark I Firearm Alternator is the Seebeck Thermoelectric Generator, part number 1261G-7L31-24CX1, sold by Custom Thermoelectric, 11941 Industrial Part Road, Suite 5, Bishopville, Md., 21813. 
     In one or more embodiments, a cooling radiator that may be attached to the Mark I Firearm Alternator to improve the efficiency of thermoelectric generators. In one or more embodiments, the radiator includes a finned heat sink and a tubular sleeve. 
     In a preferred embodiment, the heat sink has a radius of 1.00 inches when measured from the center axis to the tip of its radiator fins. The heat sink features a central hole with a 0.75 inch radius to accommodate the insertion of a Firearm Alternator into its center. The heat sink is the same length as the Firearm Alternator it surrounds, approximately 6 to 7 inches. A thin walled tubular sleeve also 6 to 7 inches in length fits around the heat sink/Firearm Alternator assembly. This tubular sleeve is mounted with a forward offset of 1.00 inch so that it overhangs the front of the heat sink/Firearm Alternator assembly and exposes a rear portion of the finned heat sink to the open air. 
     The overhang of the tubular sleeve allows the muzzle blast of Firearm Alternator to create a low pressure zone in front of the finned heat sink. This low pressure area draws cool air in from the exposed rear of the radiator. The drawn in air proceeds forward towards the muzzle of the Firearm Alternator cooling the heat sink fins. This in turn allows the heat sink to cool the thermoelectric generators of the Firearm Alternator. 
     This forced air cooling method works best in situations of sustained or rapid fire where the continued discharge of a firearm is able to maintain the low pressure zone in front of the radiator. In situations where sustained or rapid fire are not expected the tubular sleeve should be removed to allow the finned heat sink to radiate heat into the environment unencumbered. 
     In one or more embodiments, the electrical systems of the Mark I Firearm Alternator use a Hybrid Energy Storage System (HESS) of ultra-capacitor(s) and battery(s). In one or more embodiments, the electrical system includes, a thermoelectric generator, an ultra-capacitor, a lithium-polymer battery and an electrical load(s). Examples of possible electrical loads include a flashlight, a laser, an optical sighting system(s), charge port(s) for external devices (e.g., phone, radio, personal digital assistant, computer, etc.). 
     In a preferred embodiment, the thermal electric generators are expected to have a maximum output of around 5 Amps and 4 Volts providing approximately 20 watts when their hot side is 300° C. This output is expected to fluctuate greatly during firearm discharge. To compensate for this, a hybrid energy storage system consisting of ultra-capacitor(s) in parallel with lithium-polymer battery(s) will be used. This energy storage system will smooth the inconsistent output of the thermoelectric generator(s) increasing the robustness and efficiency of the Firearm Alternator electrical systems. To meet the needs of this system the ultra capacitor should be able to handle around 5 Volts. 
     Battery size is determined by the expected load. When the load is expected to be high a lithium polymer battery with a capacity of approximately 20 Watt-hours is used. For small loads a battery with a capacity of approximately 5 Watt-hours is used. 
     In one or more preferred embodiments, components of the electrical system, namely the battery, ultra capacitor and load are housed in a polymer “battery box” separate from the Firearm Alternator, this arrangement allows for better weight management by locating a large portion of the Firearm Alternator&#39;s total weight on an accessory rail system instead of the barrel of the firearm. 
     An alternative to the “battery box” arrangement is the “battery end cap”. In this configuration the front end cap of the Firearm Alternator (the end cap that doesn&#39;t interface with the firearm barrel) is extended slightly. The battery and ultra capacitor are housed in the hollowed space between the inner and outer circular walls of the end cap. A small electrical load, suitable for a 5 Watt-hour, of LED lights and/or laser(s) are inset into the forward exposed face of the end cap. This configuration allows the Firearm Alternator and its electrical systems to be built and sold as a single small compact unit. 
     In one or more preferred embodiments, an ultra capacitor cell for use in embodiments of the Mark I Firearm Alternator may be a type PBLL, passively balanced ultra capacitor module with leads and connector, sold by the Tecate Group, 7520 Mission Valley Road, San Diego, Calif., 92108. 
     The Mark I Firearm Alternator is composed of two main components: the alternator  104  and the battery box  105  ( FIG.  1   ). These components are attached separately to a firearm  101  using pre-existing mounting methods ( FIG.  1   ). In one embodiment of the invention these methods are the mounting of the battery box  105  to a NATO standard rail mounting system  102  and the attachment of the alternator  104  using a threaded barrel  103  ( FIG.  1   ). Once the components of the alternator  104 ,  105  are securely mounted to a firearm  101 , they are connected by an electrical wire  106  which facilitates the transfer of electricity from the alternator  104  to the battery box  105  ( FIG.  1   ). 
     The alternator has an insulating housing consisting of a tubular body  201 , and front  202  and rear  203  end caps ( FIG.  2   ). This housing is filled with mesh disks  204  that are compacted tightly into the internal volume of the tubular body  201  and held in place by the end caps  201 ,  202  ( FIG.  2   ). Thermoelectric generators  208 ,  209 ,  210  are mounted on top of finned aluminum plates  205 ,  206 ,  207  ( FIG.  2   ). The assemblages of thermoelectric generators and finned aluminum plates  208 / 205 ,  209 / 206 ,  210 / 207  are mounted flush with the top of the housing body  201  in recesses  211 ,  212 ,  213  that have centerline slits that allow the fins of the aluminum plates  205 ,  206 ,  207  to penetrate the internal volume of the alternator housing ( FIG.  2   ). 
     Internally, the alternator is filled with mesh disks  303  to provide a large surface area that absorbs heat from the gaseous discharge of a firearm as it is forced through the alternator from the barrel at the intake  302 , to the exhaust  301  ( FIG.  3   ). The mesh disks  401  have a central hole  402  to allow the unobstructed travel of a bullet through the alternator ( FIG.  4   ). The mesh disks also have a single dorsal cut  403  which allows it to wrap tightly around the fin of the aluminum plate  404  that the thermoelectric generator(s)  405  are mounted to allowing the transmission of heat from the mesh to the generators  405  through the aluminum  404  ( FIG.  4   ). The front edge of the aluminum fin  502  is curved and slightly pointed allowing the mesh disks  501  to slide over the aluminum fin easily, this makes the mesh disks easy to insert and remove from the alternator for cleaning, assembly and disassembly ( FIG.  5   ). 
     The alternator housing  304  is insulating polymer, this forces all the heat from the gaseous discharge of a firearm to exit the alternator one of two ways: through the exhaust  301  or through the thermoelectric generators  308 ,  309 ,  310  via the aluminum mounting plates  305 ,  306 ,  307  ( FIG.  3   ). 
     The electricity generated by the alternator is sent to an ultra-capacitor and battery housed in the battery box  601  via a connecting wire  605  from the battery box that plugs into the alternator ( FIG.  6   ). The battery box is mounted to a firearm separate from the alternator (in one embodiment using a NATO standard rail system  604 ) to keep weight off the end of the firearm&#39;s barrel. The excess electrical energy stored in the battery box is controlled by buttons  603 , in one embodiment of the invention, may be used to direct power to a flashlight  607 , laser  606 , or a USB port  602  ( FIG.  6   ). 
     Alternatively, a small battery  703 , and ultra-capacitor  702  may be placed in the rim of an enlarged front alternator end cap  701  and power, in one embodiment, a ring of LEDs  704  ( FIG.  7   ). Providing a more compact alternative to the separate battery box/alternator embodiment of this invention. 
     For greater efficiency a finned radiator  801  may be fitted around the exterior of the Firearm Alternator thereby increasing the effective surface area the Firearm Alternator&#39;s thermoelectric generators can use to cool their “cold” side ( FIG.  8   ). In situations where rapid sustained fire from a firearm is expected, the radiator may be encased in a thin sleeve  802  which leaves the rear of the radiator  803  exposed to the environment while overhanging slightly  805  the muzzle  804  of the Firearm Alternator ( FIG.  8   ). In this configuration the high velocity gas discharged from the muzzle of the Firearm Alternator  804  creates a low pressure area in the sleeve&#39;s  802  overhanging section  805  that draws air in from the rear of the radiator  803  and over the radiator&#39;s fins  801  cooling it and the cool side of the thermoelectric generators it covers ( FIG.  8   ). 
     Upon review of the present disclosure, persons of ordinary skill in the art will realize that known techniques, apparatus, and instruments used in the industry may be: used to analyze, predict, design, and measure the combustion parameters and performance within the Firearm Alternator; chosen to fabricate the various components of the Firearm Alternator.

     While the above description contains many specificities, those should not be construed as limitations on the scope of the invention, but rather as an exemplification of preferred embodiments thereto. As have been briefly described there are many possible variations. Accordingly, the scope of the inventions should be determined not only by the embodiments illustrated, but by the appended claims and their legal equivalents. 
     The specification and drawings herein are, accordingly, to be regarded in an illustrative rather than a restrictive sense. It will, however, be evident that various modifications and changes may be made thereunto without departing from the broader spirit and scope of the disclosure as set forth in the claims. 
     Other variations are within the spirit of the present disclosure. Thus, while the disclosed invention is susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in the drawings and have been described above in detail. It should be understood, however, that there is no intention to limit the disclosure to the specific form or forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions and equivalents falling within the spirit and scope of the disclosure, as defined in the appended sample claims. 
     Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without other input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. 
     Disjunctive language such as the phrase “at least one of X, Y, Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to present that an item, term, etc., may be either X, Y, or Z, or any combination thereof (e.g., X, Y, and/or Z). Thus, such disjunctive language is not generally intended to, and should not, imply that certain embodiments require at least one of X, at least one of Y, or at least one of Z to each be present. 
     The use of the terms “a” and “an” and “the” and similar referents in the context of describing the disclosed embodiments (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. The term “connected” is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of the disclosure and does not pose a limitation on the scope of the disclosure unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosure. 
     Embodiments of this disclosure are described herein, including the best mode known to the inventors for carrying out the disclosure. Variations of these embodiments may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect skilled artisans to employ such variations as appropriate and the inventors intend for the disclosure to be practiced otherwise than as specifically described herein. Accordingly, this disclosure includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the disclosure unless otherwise indicated herein or otherwise clearly contradicted by context.
