Embodiments of the present invention relate to an energy storage system. Specific embodiments pertain to a lightning energy storage system.
For years people have been attempting to find an effective and inexpensive energy source for various energy consuming facilities of modern day living, commerce, and technology. One of the prime concerns in utilizing the energy sources is how to achieve environmentally protective eco-friendly resources.
Lightning is a phenomenon of an atmospheric electrical discharge. When the electric field becomes strong enough, an electrical discharge (the bolt of lightning) occurs within clouds or between clouds and the ground. Lightning occurs with both positive and negative polarity. An average bolt of negative lightning carries an electric current of 30,000 amperes (30 kA), and transfers 15 coulombs of electric charge and 500 megajoules of energy. Large bolts of lightning can carry up to 120 kA and 350 coulombs. An average bolt of positive lightning carries an electric current of about 300 kA—about 10 times that of negative lightning.
Therefore, it would be beneficial to have an apparatus to collect and/or store the electrical energy of lightning.
Embodiments of the invention relate to an apparatus and method for collecting and/or storing the electrical energy. Specific embodiments are directed to an apparatus and method for collecting and/or storing the electrical energy of lightning. A specific embodiment pertains to a lightning energy storage system that includes a lightning rod, a wire, a lightning energy harvesting unit and a ground rod. The lightning rod is configured to attract lightning and transfer electrical energy. The lightning energy harvesting unit incorporates at least one magnetic capacitor and a switch. The magnetic capacitor comprises a first magnetic section, a second magnetic section, and a dielectric section configured between the first magnetic section and the second magnetic section. The dielectric section is configured to store the electrical energy and has a thickness of at least 10 angstrom to reduce, and preferably prevent, electrical energy leakage. The ground rod is connected to the wire. A control signal controls the switch to direct the electrical energy to ground through the ground rod or to direct the electrical energy to charge the magnetic capacitor in response to a charging state of the magnetic capacitor.
In an embodiment, the thickness of the dielectric section is 100 angstrom.
In an embodiment, the lightning energy harvesting unit further comprises a transformer connected to the wire to adjust a voltage of the electrical energy to charge the magnetic capacitor.
In an embodiment, the lightning energy harvesting unit is packaged in a box, wherein the box has an environmentally sealing cover.
In an embodiment, the lightning energy harvesting unit further comprises a detector to detect the charging state of the magnetic capacitor and issue the control signal is response to the charging state.
In an embodiment, the lightning energy harvesting unit comprises a plurality of magnetic capacitors that are parallel connection and fabricated in a substrate.
In an embodiment, the substrate further comprises a first connector and a second connector, the electrical energy charges the magnetic capacitors through the first connector and the magnetic capacitors supply the electrical energy to an external device through the second connector.
In an embodiment, the substrate further comprises a third connector connected to the ground rod.
In an embodiment, when the charging state of the magnetic capacitors are fully charged, the switch switches the first connector to connect with the third connector to direct the electrical energy to the ground rod, and when the charging state of the magnetic capacitors are not fully charged, the switch switches the first connector to connect with the magnetic capacitors to direct the electrical energy to charge the magnetic capacitors.
In order to make the foregoing as well as other aspects, features, advantages, and embodiments of the present disclosure more apparent, the accompanying drawings are described as follows:
Reference will now be made in detail to the various embodiments of the disclosure, one or more examples of which are illustrated in the figures. Each example is provided by way of explanation of the disclosure, and is not meant as a limitation of the disclosure. For example, features illustrated or described as part of one embodiment can be used in conjunction with other embodiments to yield yet a further embodiment. It is intended that the present disclosure includes such modifications and variations.
The wire 102 is disposed in connecting between the lightning rod 101 and the lightning energy harvester (LEH) unit 103 or ground rod 104. The structural adaptation of the wire 102 is such as to direct electrical energy from the lightning rod 101 to the lightning energy harvester (LEH) unit 103 for storing or the ground rod 104 for discharging.
In an embodiment, the lightning energy harvester unit 103 is packaged in a box. The box has environmentally sealed cover for safety and protection from weather elements. The lightning energy harvester (LEH) unit 103 is composed of one or more magnetic capacitor 200. Magnetic capacitor is constructed based on the GMC (Giant Magnetic Capacitance) theory. It has a capacitance 106-1017 times larger than that of standard capacitor of equivalent dimensions and dielectric materials. A magnetic capacitor is an energy storage apparatus.
In another embodiment, a plurality of magnetic capacitors 200 may be fabricated in a substrate 240 together to form the lightning energy harvester unit 103 as illustrated in
In another embodiment, the lightning energy harvester unit 103 further comprises a power management module 260. The power management module 260 connects to the wire 102 through a connector 251 and connects to the ground rod 104 through the connector 252. The power management module 260 includes a detector 2601 and a switch 2602. The detector 2601 detects the magnetic capacitor 200 to determine an electrical energy state stored in the magnetic capacitors 200. In an embodiment, when the electrical energy stored in the magnetic capacitors 200 is over a set value, the detector 2601 issues a control signal to the switch 2602 to switch the switch 2602 to direct the electrical energy in lightning to ground through the ground rod 104. For example, the lightning rod 101 receives the electrical energy in lightning to charge these magnetic capacitors 200. The detector 2601 detects the charging state of theses magnetic capacitor 200 in real time. When the detector 2601 determines these magnetic capacitors 200 are fully charged, the detector 2601 issues a control signal to switch the switch 2602 to direct the electrical energy in lightning to ground through the ground rod 104. Moreover, in a specific embodiment, the power management module 260 further includes a transformer 2603 to transform the voltage of the electrical energy in lightning to a charging voltage to charge these magnetic capacitors 200.
