     DETAILED DESCRIPTION 
     Mcap (Magnetic Capacitor) is an energy storage technology. This technology increases the energy storing capability more than 1 billion times compared with conventional capacitors, within the same volume and weight. Utilizing this technology rather than the standard used technology would bring much greater efficiency to this market. 
       FIG. 1  shows a schematic diagram of Mcap to store electrical energy according to an embodiment of the invention. An Mcap  100  has a first magnetic section  110 , a second magnetic section  120 , and a dielectric section  130  configured between the first magnetic section  110  and the second magnetic section  120 . The dielectric section  130  is arranged to store electrical energy, and the first magnetic section  110  and the second magnetic section  120  with dipoles are arranged to prevent electrical energy leakage. The dielectric section  130  is a thin film, and the dielectric section  130  is composed of dielectric material, such as BaTiO 3  or TiO 3 . A plurality of Mcap  100  can be fabricated in a substrate  201  together to form an Mcap cell  200  as illustrated in  FIG. 2 . A first connector  202  is formed in the substrate  201  for connecting to an external device. These Mcaps  100  are parallel connection and connected to the connector  202 . Moreover, a plurality of Mcap cell  200  can be integrated into a Mcap module  300 . In an embodiment, these Mcap cells  200  are stacked together to form a Mcap module  300  as illustrated in  FIG. 3 . 
     However, each Mcap module, when fully charged, carries enough power to cause serious injuries or death if not handled properly. Similarly, poor environmental protection will also lead to electrical short circuit resulting in serious damage. Therefore, a safe storage unit is needed to protect an Mcap module. 
       FIG. 4A  illustrates a schematic diagram of a storage unit for an Mcap module according to embodiment of the present invention.  FIG. 4B  is a cross-section view diagram from AA′ line in the  FIG. 4A . The storage unit  400  is utilized to install an Mcap module  300  therein. The storage unit  400  includes a housing part  401  and cover part  402 . The housing part  401  includes four side walls  401   a ,  401   b ,  401   c  and  401   d , a bottom wall  401   e  and an opening  410 . The side wall  401   a  faces the side wall  401   c . The side wall  401   b  faces the side wall  401   d . A first electrode  407  formed in the side wall  401   a . A second electrode  408  formed in the side wall  401   c . The first electrode  407  and the second electrode  408  serve as an anode and a cathode. That is, when an Mcap module  300  is loaded in the storage unit  400  from the opening  410 , the Mcap module  300  can supply power to an external device though the first electrode  407  and the second electrode  408 . Therefore, an external device can be powered by the Mcap module  300 . 
     In this embodiment, when the Mcap cells  200  are loaded into the housing part  401 , the Mcap cells  200  are arranged in parallel with the side wall  401   b  and  401   d . A plurality of track sets  403  are formed in the inside of the side walls  401   b  and  401   d . Each track set  403  includes a track for slipping a corresponding Mcap cell  200  into the housing part  401 . In this embodiment, the track set  403  consists of two parallel tracks  403   a  and  403   b  that have lengths similar to an edge of the Mcap cell  200 . The form of each of the two tracks is L-shaped toward the same orientations. The geometric characteristics of the tracks are not limited herein. 
     Moreover, a plurality of second connectors  405  are formed in the inside of the bottom side  404 . These second connectors  405  are electrically connected together by a conductor wire  406  formed in the inside of the bottom side  404 . The conductor wire  406  are connected to the first electrode  407  and the second electrode  408 . When Mcap cells  200  are loaded into the housing part  401  through track sets  403 , the first connectors  202  of the Mcap cells  200  are connected to the second connectors  405 . Because the second connectors  405  are electrically connected together by a conductor wire  406 , all Mcap cells  200  are also electrically connected together. Moreover, because the conductor wire  406  are connected to the first electrode  407  and the second electrode  408 , the Mcap cells  200  can be powered or power an external device through the first electrode  407  and the second electrode  408 . In another embodiment, two additional magnetic mechanism  410  and  412  are formed in the side walls  401   b  and  401   d  respectively. The magnetic mechanism  410  and  412  can help the storage unit  400  to load or unload a system. This will be described in the following paragraphs. 
     When all Mcap cells  200  are loaded into the housing part  404 , the housing part  404  is sealed by the cover part  402  to protect the Mcap cells  200  therein. 
     On the other hand, a load unit  500  is used to pack the storage unit  400  for improving a process of loading an Mcap module.  FIG. 5A  illustrates a schematic diagram of a load unit. The load unit  500  includes a housing  501  and a seal  502 . The storage unit  400  is located on the seal  502  and the housing  501  covers the storage unit  400 . 
       FIG. 5B  is a schematic diagram of the storage unit loaded in the load unit.  FIG. 5C  is a cross-section view diagram from BB′ line in the  FIG. 5B . A load mechanism, such a spring or a magnetic mechanism, is disposed in the inside of the top surface  503  of the load unit  500 . The load mechanism  503  can protect the storage unit  400  from crashing the load unit  500 . Moreover, the load mechanism also can help to load the storage unit  400  to load unit  500 . In an embodiment, the load mechanism  503  is a magnetic mechanism. In this case, the magnetic mechanism  408  disposed in the surface  401   b  of the storage unit  400  has a special magnetic pole. When the storage unit  400  is loaded into the load unit  500 , the load mechanism  503  is adjusted to have a magnetic pole different from the special magnetic pole of the storage unit  400 . Therefore, the load unit  500  attracts the storage unit  400 . On the other hand, when the storage unit  400  is unloaded from the load unit  500 , the load mechanism  503  is adjusted to have a magnetic pole same as the special magnetic pole of the storage unit  400 . Therefore, the storage unit  400  can leave the load unit  500  by a repulsion. 
       FIG. 6A  illustrates a schematic diagram of loading an Mcap module in a system according to an embodiment of the present invention. In this embodiment, the Mcap module  300  provides power to an external system  600 , such as an electric vehicle. The system  600  has a location part  602  to carry the Mcap module  300 . A dust cover  608  covers the location part  602 . Two electrodes  603  and  604  are formed in the sidewalls  602   a  and  602   b  of the location part  602  respectively. Moreover, two conductor wires  605  and  606  connect with the two electrodes  603  and  604  respectively. Electrical elements of the system  600  connect with the two conductor wires  605  and  606 . The height of the two electrodes  603  and  604  is equal to that of the first electrode  407  and the second electrode  408  of the storage unit  400 . Therefore, when the Mcap module  300  is loaded into the location part  602 , the first electrode  407  and the second electrode  408  connect with the two electrodes  603  and  604  respectively. That is, the power supplied by the Mcap module  300  is carried by the conductor wires  605  and  606  and transmits to the electrical elements in the system  600 . 
     In another embodiment, an eject mechanism  607  is disposed in the bottom of the location part  602 . The eject mechanism  607  protects the storage unit  400  from crashing the bottom side of the location part  602  when the storage unit  400  is loaded into the location part  602 . That is, the eject mechanism  607  acts as a buffer. The eject mechanism  607 , for example, is a spring or a magnetic mechanism. In an embodiment, the eject mechanism  607  can cooperate with the load mechanism  503 . For example, both the eject mechanism  607  and the load mechanism  503  are magnetic mechanism. When the storage unit  400  is loaded into the location part  602 , the seal  502  of the load unit  500  is removed first. Then, the load mechanism  503  is adjusted to have a magnetic pole same as the magnetic pole of the magnetic mechanism in the side wall  401   b  of the storage unit  400  and the eject mechanism  607  is adjusted to have a magnetic pole different from the magnetic pole of the magnetic mechanism in the side wall  401   d  of the storage unit  400 . Accordingly, the storage unit  400  can leave the load unit  500  by a repulsion between the magnetic mechanism  410  and the load mechanism  503  and is loaded into the location part  602  by an attraction power between the eject mechanism  607  and the magnetic mechanism  412 . After the storage unit  400  is loaded into the location part  602 , the dust cover  608  covers the location part  602  as shown in the  FIG. 6B . 
       FIG. 7A  illustrates a schematic diagram of unloading a Mcap module in a system according to an embodiment of the present invention. When the storage unit  400  is unloaded from the location part  602 , the seal  502  of the load unit  500  is removed first. Then, the load mechanism  503  is adjusted to have a magnetic pole different from the magnetic pole of the magnetic mechanism  410  of the storage unit  400  and the eject mechanism  607  is adjusted to have a magnetic pole the same as the magnetic pole of the magnetic mechanism  412  of the storage unit  400 . Accordingly, the storage unit  400  can leave the location part  602  by a repulsion power between the eject mechanism  607  and the magnetic mechanism  412  and is loaded into the load unit  500  by an attraction power between the magnetic mechanism  410  and the load mechanism  503 . After the storage unit  400  is loaded into the load unit  500 , the dust cover  608  covers the location part  602  as shown in the  FIG. 7B . 
     In another embodiment, a continuous loading Mcap module mechanism is adopted to load a plurality of Mcap module in a system when this system requires a plurality Mcap module to supply power.  FIG. 8  illustrates a schematic diagram of a continuous loading Mcap module mechanism. In this case, a plurality of load unit  500  is arranged in a row. The load units  500  are moved to follow the direction  500 . Therefore, the storage units  400  are sequentially loaded into the location part  802 . In this embodiment, the eject mechanism  807  is a spring and acts as a buffer. The eject mechanism  807  protects the storage units  400  from crashing the bottom side of the location part  802  when the storage units  400  are loaded into the location part  802 .
