     BEST MODE 
       [0049]    Hereafter, embodiments of the inventive concept will be described in conjunction with the accompanied figures. Embodiments of the inventive concept may be variable in various forms and the scope of the inventive concept may not be construed as restricting the following embodiments. These embodiments will be provided to help those skilled in the art to fully comprehend the inventive concept as possible. Shapes or patterns of the accompanied figures are exaggerated for more clearly illustrating structural configurations of elements in the figures. 
         [0050]    In the specification, in the case that an element is described as being on a second element, it means that the element may be formed on second element or a third element is interposed between the element and the second element. Additionally, in the figures, thicknesses of films or areas are exaggerated for clear explanation and illustration of technical matters. 
         [0051]    In various embodiments of the specification, the terms ‘first’, ‘second’, ‘third’, and so on are used for enumerating a number of elements, whereas those elements may not be restrictive to such terms. Those terms will be merely used to differentiate an element from another element each other. Accordingly, a first element of an embodiment may be indicated as a second element in another embodiment. Embodiments described and exemplified herein may also include their complementary embodiments. Additionally, the term ‘and/or’ in the specification will be used as including at least one of elements written before and after it. 
         [0052]    In the description, the terms of a singular form may also include plural forms unless otherwise specified. The term ‘include’, ‘have’, or its diverse inflections or conjugations is presence of a feature, a number, a step, an element, or a combination of them which is described in the specification, and may not be construed as excluding presence or addition with one or more features, numbers, steps, elements, or combinations of them. Additionally, the term ‘connect’ used herein will be used to mean all cases of connecting a plurality of elements directly and indirectly. 
         [0053]    Additionally, some descriptions will not be provided in the case that the details about known functions or configurations rather cause the points of the inventive concept to be vague unnecessarily. 
         [0054]      FIG. 1  illustrates an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept. 
         [0055]    Referring to  FIG. 1 , an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may include a rectifying part  120  and a storing part  130 . 
         [0056]    The rectifying part  120  may rectify an alternating current (AC). The rectifying part  120  may transmit a rectified AC to the storing part  130 . 
         [0057]    The AC may be a surface current generated from the mechanism that an electronic wave meets a conductive material. The surface current may flow along the surface of the conductive material. For example, an AC may be a current, for which an electronic wave generated from diverse electronic devices (e.g., a power consumption apparatus such as computer, refrigerator, television, mobile phone, and so on, or a power transport apparatus) is converted into a surface current, flowing into a ground. As another example, the AC may be a current, for which an electronic wave generated in the inside or outside of a building is converted into a surface current, flowing into a ground of the building. 
         [0058]    Different from the aforementioned embodiment, an energy conversion and storage apparatus using an electronic wave in accordance with another embodiment of the inventive concept may further include an electronic wave-current converting part  110 . In this configuration, the electronic wave-current converting part  110  may convert an electronic wave, which is received from an external source, into an AC. For example, the electronic wave-current converting part  110  may be shaped in a sheet or mesh made of a conductive material. According to an embodiment, the sheet-type electronic wave-current converting part  110  may be formed in an uneven form having concaves and convexes. 
         [0059]    In a microscopic view, an electronic wave incident on a conductive material generates an AC that flows along the surface of the conductive material, and the AC regenerates an electronic wave. The regenerated electronic wave is reflected on the conductive material. 
         [0060]    An energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may transmit an AC, which is generated by an electronic wave, to the rectifying part  120  before the AC generated by the electronic wave is converted again into an electronic wave. Accordingly, an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may store an AC, which is generated through conversion of an electronic wave, as electric energy. 
         [0061]      FIG. 2  is a flow chart showing an energy conversion and storage method using an electronic wave in accordance with an embodiment of the inventive concept. 
         [0062]    An electronic wave may be received from an external source (S 110 ). The electronic wave may include electronic waves generated from diverse electronic devices. The electronic wave may be converted into an AC (S 120 ). According to an embodiment of the inventive concept, the electronic wave, as described with  FIG. 1 , may be converted into an AC through the electronic wave-current converting part  110 . The AC may be rectified (S 130 ). The rectified AC may be stored in the storing part  130  described with  FIG. 1  (S 140 ). 
         [0063]      FIG. 3  is a circuit diagram illustrating an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept. 
         [0064]    Referring to  FIG. 3 , an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may include first to fourth diodes  121 ,  122 ,  123 , and  124 , and a capacitor  132  connected with the diodes  121 ,  122 ,  123 , and  124  and forming the storing part. 
         [0065]    An AC outputting part  112  may convert an electronic wave into an AC and may output the AC to a first node N 1 . The AC outputting part  112  may be an electronic wave-current converting part  110  which is described with  FIG. 1 . Different from this, the electronic wave-current converting part  110  may be an electronic device outputting an AC generated by conversion of an electronic wave. 
         [0066]    A cathode of the first diode  121  may be connected to the first node N 1 . An anode of the second diode  122  may be connected to the first node N 1 . A cathode of the second diode  122  may be connected to one end  132   a  of the capacitor  132 . An anode of the first diode  121  may be connected to the other end  132   b  of the capacitor  132   b.    
         [0067]    An anode of the third diode  123  may be connected with the anode of the first diode  121 . A cathode of the third diode  123  may be connected with a grounding part  142  to provide a ground to the cathode of the third diode  123 . 
         [0068]    A cathode of the fourth diode  124  may be connected with one end  132   a  of the capacitor  132 . An anode of the fourth diode  124  may be connected with the grounding part  142  to provide a ground to an anode of the fourth diode  124 . 
         [0069]    The first to fourth diodes  121 ,  122 ,  123 , and  124  may rectify an AC that is generated by conversion of an electronic wave, and may transmit the rectified AC to the capacitor  132 . The capacitor  132  may store the rectified AC as electric energy. 
         [0070]    In detail, an (+)-polarized component of the AC generated by conversion of an electronic wave may pass the second diode  122  and may be stored in the one end  132   a  of the capacitor  132 . While the (+)-polarized component of the AC is being stored in the capacitor  132 , the third diode  123  and the grounding part  142  may provide a ground to the other end  132   b  of the capacitor  132 . 
         [0071]    A (−)-polarized component of the AC generated by conversion of an electronic wave may pass the first diode  121  and may be stored in the other end  132   b  of the capacitor  132 . While the (−)-polarized component of the AC is being stored in the capacitor  132 , the fourth diode  124  and the grounding part  142  may provide a ground to the one end  132   a  of the capacitor  132 . 
         [0072]    Summarily, the first to fourth diodes  121 ˜ 124  and the grounding part  142  may provide a ground to the other end  132   b  of the capacitor  132  in the section for which the AC is (+)-polarized, while may provide a ground to the one end  132   a  of the capacitor  132  in the section for which the AC is (−)-polarized. 
         [0073]    That is, according to a polarity of the AC, one of the one end  132   a  and the other end  132   b  of the capacitor  132  may be switched into a ground. In detail, in a (+)-polarized section of the AC, the other end  132   b  of the capacitor  132  may be provided with a ground, and in a (−)-polarized section of the AC, the one end  132   a  of the capacitor  132  may be provided with a ground. 
         [0074]    The grounding part  142  may be implemented in various forms. The grounding part  142  may be directly connected with the third and fourth diodes  123  and  124  which form the rectifying part, but may not be directly connected with the storing part  132 . 
         [0075]    For example, in the case that an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept stores an AC that is generated by conversion of the electronic wave generated from an electronic device placed in the inside or outside of a building, the grounding part  142  may be a ground rod of the building. In this case, as the ground rod increases in a mass, electric energy stored in the capacitor may increase in a storage rate. Additionally, as the ground rod increases in a volume, the electric energy stored in the capacitor  132  increases in a storage rate. Additionally, as the ground rod increases in electrical conductivity, the electric energy stored in the capacitor  132  increases in a storage rate. 
         [0076]    As another example, in the case that an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept stores an AC that is generated by conversion of an electronic wave generated from a household electrical appliance (e.g., refrigerator, computer, or washing machine), the grounding part  142  may be an outlet ground. 
         [0077]    As still another example, in the case that an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept stores an AC that is generated by conversion of an electronic wave generated from a portable electronic device (e.g., mobile phone or MP3 player), the grounding part  142  may be a virtual ground or a neutral ground. In this case, an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may further include the grounding part  142 . 
         [0078]      FIG. 4  illustrates a modification of an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept. 
         [0079]    Referring to  FIG. 4 , an AC outputting part  122  and first to fourth diodes  121 ,  122 ,  123 , and  124 , which are described with  FIG. 3 , may be also provided to the modification of the energy conversion and storage apparatus. The modification of the energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept may further include an additional circuit  150  which is connected with one end  132   a  and the other end  132   b  of a capacitor  132 . 
         [0080]    The additional circuit  150  may be an electrical contact switch. In the case that electric energy stored in the opposite ends  132   a  and  132   b  of the capacitor  132  is charged in a level equal to or larger than a specific level, the electrical contact switch may be closed to discharge the electric energy. Due to this operation, the energy conversion and storage apparatus according to an embodiment of the inventive concept may be protected from an overcharge. 
         [0081]    Different from the aforementioned embodiments, the additional circuit  150  may be am amplifying circuit. In this configuration, the amplifying circuit may amplify electric energy, which is stored in the opposite ends  132   a  and  132   b  of the capacitor  132 , and may provide the amplified electric energy to another device. 
         [0082]    Otherwise, different from the aforementioned embodiments, the additional circuit  150  may include all of the electrical contact switch and the amplifying circuit. 
         [0083]      FIGS. 5 and 6  illustrate additional circuits included in a modification of an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept. 
         [0084]    Referring to  FIG. 5 , an additional circuit  150   b  may be connected to opposite ends of a capacitor  132  of the energy conversion and storage apparatus using an electronic wave described with  FIG. 3 . The additional circuit  150   b  may include a timer T and a power transmission element ED. 
         [0085]    The timer T and the power transmission element ED of the additional circuit  150   b  may allow electric energy, which is stored in the capacitor  132 , to be transmitted to another device every lapse of a reference time. For example, every 10 seconds, electric energy stored in the capacitor  132  may be transmitted to another device (e.g., television or refrigerator) which needs electricity. Otherwise, electric energy stored in the capacitor  132  may be transmitted to a power storage facility every such a reference time. The reference time may be set differently in accordance with a kind of device generating an electronic wave. 
         [0086]    Referring to  FIG. 6 , an additional circuit  150   c  may be connected to opposite ends of a capacitor  132  of the energy conversion and storage apparatus using an electronic wave described with  FIG. 3 . The additional circuit  150   c  may include a switch S and a power transmission element ED. The switch S may be an electrical contact switch. The electrical contact switch may be disposed in a vacuum tube. The switch S may be connected to opposite ends  132   a  and  132   b  of the capacitor  132 . If a voltage stored in the capacitor  132  is equal to or higher than a reference voltage, the switch S may be closed. In the case that the switch S is closed, electric energy stored in the capacitor  132  may be transmitted through the power transmission element ED to another device (e.g., television or refrigerator) which needs electricity. Otherwise, electric energy stored in the capacitor  132  may be transmitted to a power storage facility every reference time. The reference time may be set differently in accordance with a kind of device generating an electronic wave. 
         [0087]      FIG. 7  is a graphic diagram showing an initial charge rate of a voltage stored in a capacitor of an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept, diversifying a kind of grounding part in the circuit diagram described in conjunction with  FIG. 3 . 
         [0088]    Referring to  FIG. 7 , Experiment 1 to Experiment 4 are differentiated in a kind of grounding part in the circuit diagram described with  FIG. 3 . Experiment 1 is performed without a grounding part and Experiment 2 employs a human body as the grounding part. Experiment 3 uses an outlet ground as a grounding part and Experiment 4 uses a virtual ground as a grounding part. In each experiment, the measurement is conducted for the maximum potential differences between the grounding part and an AC that is generated by conversion of an electronic wave generated a desktop body, and for an initial charge rate. 
         [0089]    In Experiment 1, the maximum potential difference between the grounding part and an AC that is generated by conversion of an electronic wave was measured in about 5.8˜6.8 V, and an initial charge rate of a voltage stored in a capacitor was measured in about 0.02 V/S. 
         [0090]    In Experiment 2, the maximum potential difference between the grounding part and an AC that is generated by conversion of an electronic wave was measured in about 35.28 V, and an initial charge rate of a voltage stored in a capacitor was measured in about 0.5 V/S. 
         [0091]    In Experiment 3, the maximum potential difference between the grounding part and an AC that is generated by conversion of an electronic wave was measured in about 108.4 V, and an initial charge rate of a voltage stored in a capacitor was measured in about 2.27 V/S. 
         [0092]    In Experiment 4, the maximum potential difference between the grounding part and an AC that is generated by conversion of an electronic wave was measured in about 99.6 V, and an initial charge rate of a voltage stored in a capacitor was measured in about 1.26 V/S. 
         [0093]    From Experiment 1 to Experiment 4, it can be seen that the maximum potential difference between a grounding part and an AC that is generated by conversion of an electronic wave may be modulated according to a kind of grounding part which provides a ground to a capacitor. Additionally, it can be seen that as the maximum potential difference between a grounding part and an AC that is generated by conversion of an electronic wave increases, an initial charge rate of a voltage stored in a capacitor may increase. Accordingly, according to a kind of grounding part which provides a ground to a capacitor, it may be allowable to modulate a charge rate of electric energy stored in the capacitor. 
         [0094]      FIG. 8  a graphic diagram showing an initial charge rate of a voltage stored in a capacitor of an energy conversion and storage apparatus using an electronic wave in accordance with an embodiment of the inventive concept, diversifying a kind of grounding part into an outlet ground and a virtual ground in the circuit diagram described in conjunction with  FIG. 3 . 
         [0095]    Referring to  FIG. 8 , Experiment 1 to Experiment 3 use the grounding part as the outlet ground in the circuit diagram described with  FIG. 3 , and Comparison 1 to Comparison 3 use the grounding part as the virtual ground in the circuit diagram described with  FIG. 3 . 
         [0096]    Experiment 1 and Comparison 1 represents initial charge rates of a voltage that is rectified from an AC, which is converted from an electronic wave generated from a computer with power consumption rate of 400 W, and stored in a capacitor. Experiment 2 and Comparison 2 represents initial charge rates of a voltage that is rectified from an AC, which is converted from an electronic wave generated from a microwave oven with power consumption rate of 1050 W, and stored in a capacitor. Experiment 3 and Comparison 3 represents initial charge rates of a voltage that is rectified from an AC, which is converted from an electronic wave generated from a television with power consumption rate of 100 W, and stored in a capacitor. 
         [0097]    In Experiment 1 and Comparison 1, the initial charge rates were measured respectively in 2.27 V/S and 1.26 V/S. In Experiment 2 and Comparison 2, the initial charge rates were measured respectively in 0.95 V/S and 0.75 V/S. In Experiment 3 and Comparison 3, the initial charge rates were measured respectively in 1.2 V/S and 0.9 V/S. From Experiments and Comparisons, it can be seen that using the grounding part as an outlet ground is higher in an initial charge rate than using the grounding part as a virtual ground. 
         [0098]      FIG. 9  is a graphic diagram showing a result of measuring power generated when an electronic-wave energy conversion and storage apparatus, which has been charged, is being discharged in accordance with an embodiment of the inventive concept, diversifying a kind of grounding part into an outlet ground and a virtual ground in the circuit diagram described in conjunction with  FIG. 3 . 
         [0099]    Referring to  FIG. 9 , power was measured through Comparison 1 to Comparison 3 and Experiment 1 to Experiment 3 which are described with  FIG. 7 . 
         [0100]    In Experiment 1 and Comparison 1, power was measured respectively in 61 W and 33.7 W. In Experiment 2 and Comparison 2, power was measured respectively in 24.3 W and 19.5 W. In Experiment 3 and Comparison 3, power was measured respectively in 20 W and 13.7 W. From Experiments and Comparisons, it can be seen that using the grounding part as an outlet ground is higher in power than using the grounding part as a virtual ground.
