MOTION ENERGY HARVESTING DEVICE The present invention relates to a motion energy harvesting device, and in particular a portable kinetic energy device, configured to use kinetic motion to create momentum which is converted into usable electrical currents. BACKGROUND OF INVENTION There are many scientific apparatus for conservation of momentum, motion and energy. However, there are various issues relating to mechanical impedance which impact the conservation of momentum, motion and energy in these instruments that are well-known in the art. In 17th century, Edme Mariotte designed the invention commonly know as the Newtons cradle attributed to Newtons laws of physics regarding the conservation of momentum, motion and energy. The Newtons cradle has found itself used as a relaxing executive desktop toy through to scientists laboratory demonstrations to suit a variety of conditions. It has probably been one of the most successfully sold apparatus commercially sold as a desktop toy since 1960’s worldwide. In the classroom, this device can be used by educators to demonstrate the principles behind momentum and the conservation of energy. Traditionally, a user pulls back one of the metal spheres to a desired height before releasing it. As the sphere swings back to its starting position, it impacts the row of spheres creating a shockwave of elastic collisions, conserving and transferring a shockwave of vibrational energy through the group of spheres and sending almost the exact energy and force to the opposite row end causing the last sphere to absorb the shockwave of energy containing velocity and mass. The last sphere has no end mass force pushing against it, so the velocity carries the mass to swing upwards almost matching the starting height where the original sphere was released. While useful in demonstrating these principles, most Newton’s Cradle type instruments allow the effects of mechanical impedance to violate conservation of momentum and energy. Accordingly, there is a need in the art for an energy harvesting device with improved conservation of momentum, motion and energy.

It is however to be understood that one or more, for example each, RMI within the device may be different to other RMIs within the device. The features of one or more RMIs within the device may vary, such as for example by varying the number of magnetic components, varying the shapes of the magnetic components, varying the separation between adjacent magnetic components, varying the magnetic field strength of the magnetic components, varying the present of the arm member(s) etc. The magnetic forces experienced and created by a first RMI within the device may also interfere with the magnetic forces experienced and created in an adjacent RMI within the device, and vice versa, creating complex oscillations. The separation between adjacent RMIs within the device may be adjustable in order to vary the oscillation movement of the magnetic component(s) within each RMI. The RMIs within the device of the present invention use an entanglement of repelling magnetic forces between adjacent magnetic components to provide the oscillation movement which is energised by the array of solenoids. The magnetic component(s) are initially positioned between the side supports in stable equilibrium. The repelling magnetic forces between adjacent magnetic components create an unstable equilibrium causing oscillation movement whilst the magnetic components are trying to rebalance the forces to 0 net G force. In turn, the solenoid coil is excited by alternating electromagnetic forces producing electricity therein. The imbalance of the unstable equilibrium creates a complex pattern of movement thus conserving motion, momentum and energy, which is converted by edi currents that energise each array of solenoid coils to produce alternating current. The movement of the magnetic components continues to produce energy long after the initial force has been applied to the device and for over a much increased time period due to the method of conservation in energy provide by low frictional, non-collisional momentum. The magnetic components may be spaced apart from each other at predetermined distances relative to the side portions. The movement of a magnetic component towards an adjacent magnetic component, whilst experiencing magnetic repulsion forces, provides complex oscillation movement (for example complex harmonic motion and pendulum coupling) of the magnetic components along the alignment axis within a single plane. The device may be configured to be operated by a mobile app. The device may be configured for communication with or to form part of a data gathering system.

DETAILED DESCRIPTION With reference to the Figures, the motion energy harvesting device 1 comprises eight repelling magnetic instruments (RMIs) 2 provided in a 2 x 2 x 2 array. It is however to be understood that the device may comprise any suitable number of RMIs provided in any suitable array. Each repelling magnetic instrument 2 comprises a pair of spaced apart side supports 3a, 3b. Each side support 3a, 3b has a first end 4a, 4b and an opposed second end 5a, 5b defining a first longitudinal axis extending therebetween. In the illustrated embodiment, the side supports extend substantially parallel to each other. It is however to be understood that the side supports may extend at any suitable angle relative to each other. Each repelling magnetic instrument comprises a plurality of magnetic components 6, each comprising a magnetic source, positioned between the pair of spaced apart side supports 3a, 3b. Each magnetic component is positioned adjacent, and spaced apart at a predetermined distance from, an end of an adjacent magnetic component. The magnetic components 6 are aligned along an alignment axis extending substantially parallel to the first longitudinal axis. Each magnetic component is configured to repel the adjacent magnetic component(s). The illustrated RMIs are identical in features. It is however to be understood that the features of one or more RMIs may vary depending on the requirements. For example, the number of magnetic components present within each RMI may vary. The magnetic field strength of the magnetic sources may also vary. The shapes and dimensions of the magnetic components may also vary. Each RMI 2 comprises a base 7 extending between the side portions 3a, 3b. A chamber 8 is defined between the base and the side portions 3a, 3b. The RMI comprises a plurality of pairs of resilient members 9. Each pair of resilient members 9 extend from the base 7 and engage the corresponding ends of a magnetic component 6 such that the magnetic component 6 is supported thereon. It is however to be understood that the magnetic components may be mounted in any suitable way. In one embodiment, one or more of the magnetic components may be suspended on non-elastic V- shaped pendulum lines. The device further comprises a power source 10 in the form of a battery pack (i.e. a rechargeable battery pack). The device further comprises an array of solenoids positioned adjacent the at least one magnetic components 6. Circuitry connects the array of solenoids and the power source. The circuitry is configured to rectify an AC voltage generated by the oscillation movement of the magnetic components 6 relative to the at least one solenoid into a DC voltage, and to supply the DC voltage to the power source to charge the power source 10. The device 1 further comprises a housing 11 configured to receive and encompass the RMIs, power source, circuitry and array of solenoids therein. In the illustrated embodiment, the housing is substantially rectangular in cross-section. It is however to be understood that the housing 11 may have any suitable shapes and dimensions. The housing 11 comprises an upper housing portion 12 configured for slideable releasable engagement with lower housing portion 13, with a cavity defined therebetween. It is however to be understood that the housing may comprise any suitable number of housing portions configured in any suitable manner to substantially encompass the RMI, power source, circuitry and array of solenoids. The upper housing portion 12 supports a solar panel 14 thereon. The circuitry connects the solar panel 13 to the power source. It is to be understood that in one or more embodiments, the housing 11 may be free of a solar panel. The housing 11 further provides four ports 15 in communication with the security and power source. The ports may be selected from USB, USB C or 12 v connectors. The magnetic component(s) are initially positioned between the side supports in stable equilibrium. Movement of the device 1 causes oscillation of the components. The repelling magnetic forces between adjacent magnetic components 6 create an unstable equilibrium causing oscillation movement whilst the magnetic components are trying to rebalance the forces to 0 net G force. In turn, the solenoid coil is excited by alternating electromagnetic forces producing electricity therein. The imbalance of the unstable equilibrium creates a complex pattern of movement thus conserving motion, momentum and energy, which is converted by edi currents that energise each array of solenoid coils to produce alternating current. The circuitry converts the AC voltage into a DC voltage for charging the power source 10. Furthermore, on exposure to sunlight the solar panel 13 generates DC voltage which the circuits provides to the power source 10. The movement of the magnetic components continues to produce energy long after the initial force has been applied to the device and for over a much increased time period due to the method of conservation in energy provide by low frictional, non-collisional momentum. The present invention therefore provides a motion energy harvesting device which couples the oscillation of repelling magnetic components within RMIs with the conversion of solar energy to charge a power source.
