  • the invention may adopt other forms within the scope of the present invention.
  • Some energy sources like batteries are portable and can be relatively cost effective to use. However, batteries must be periodically replaced or recharged, which can make them inconvenient to use in many applications. For example, current mobile phone batteries usually require recharging every day or two, depending on the level of phone usage. If an improved or alternative power source was provided for phones that reduced or obviated the need to constantly recharge phone batteries then this would provide a significant advancement in phone technology. Also, batteries are generally not suitable for providing a constant source of energy in large scale applications.

  • FIG. 10 there is illustrated an energy conversion device 10.
  • the device 10 includes a housing, although the housing has not been shown for clarity purposes.
  • the device 10 includes a magnet 12.
  • the device 10 includes two magnets 12, as visible in Figure 6 - although it is to be appreciated that any practical number of magnets 12 may be utilised in the device 10. For the purposes of this discussion, a single magnet will be described.
  • the magnet 12 is a permanent block magnet manufactured from a ferromagnetic material.
  • the magnet 12 is mounted in position on a support in the form of a plate 14.
  • the plate 14 is centrally mounted to vertically extending shaft 16.
  • the shaft 16 is rotatably mounted in position to the housing (or a stationary support).
  • the shaft 16 is rotatable about an axis 18. In the illustrated embodiment, the plate 14 and shaft 16 (and therefore also the magnet 12) rotate in a counter-clockwise direction.
  • the axis 18 is concentrically located within the shaft 16.
  • Rotation of the shaft 16 and plate 14 relative to the housing defines a circular path 20 defined by the magnet 12. It can be seen that the path 20 is provided in a horizontal plane, although the path 20 may be provided in an alternative orientation.
  • the device 10 also includes an array of magnet attractors 22.
  • each magnet attractor 22 is of a ferromagnetic material.
  • a large array of closely mounted and equidistantly spaced magnet attractors 22 is provided within the device 1 0.
  • the magnet attractors 22 are provided in a circular array. For clarity, only two magnet attractors 22 have been shown in Figure 2, and several random magnet attractors 22 have been shown in each of Figures 4 to 6.
  • Each magnet attractor 22 is provided along the circular path 20. It is to be appreciated, however, that each magnet attractor 22 is independently movable from its respective position along the path 20 (as per each of magnet attractors 22a shown in Figure 4) to a respective position displaced radially outwards from the path 20 (as per each of magnet attractors 22b shown in Figure 4). Movement of each magnet attractor 22 is a pivoting movement, by virtue of each magnet attractor being associated with and pivotably connected to a respective mechanism (or support) 24. Each magnet attractor 22 is pivotably connected to its associated mechanism 24 at pivot mount 26. The body 28 of each mechanism 24 is fixed in position about (but not to) the plate 14. The plate 14 (with the magnet 12 attached) rotates within an area bounded by the stationary bodies 28.
  • the magnet 12 moves along the circular path 20 by way of its magnetic attraction towards each respective magnet attractor 22 provided along the path 20.
  • the magnet 12 is capable of moving at least substantially continuously along the path 20, thereby advantageously providing an energy conversion device 10 that is at least substantially continuously operable. Movement of the magnet 12 along the path 20 may be smooth, or staggered/pulsed. The precise nature of the movement may, at least in part, be dependent on whether contact is made between the magnet 12 and each of the magnet attractors 22.
  • the magnet 12 moves towards each magnet attractor 22, but (at least in one embodiment) never comes into contact with it, since each attractor 22 is moved out of the way of the magnet 12 (to the position of magnet attractors 22b shown in Figure 4) shortly before the magnet 12 reaches and makes physical contact with it, whereupon the magnet 12 is then drawn towards the next magnet attractor 22 provided along the path.
  • this magnetic attraction between the magnet 12 and each of the attractors 22 facilitates at least substantially continuous rotation of the magnet 12, plate 14 and shaft 16.
  • the precise operating arrangement may be selected so as to optimise the performance characteristics for a given intended application.
  • Each of the mechanisms 24 is provided for the sole purpose of moving its respective attractor 22 out of the way of the rotating magnet 12 on each revolution of the magnet 12; and also to return each attractor 22 back into its position on the path 20 once the magnet 12 has passed. This occurs for every pass of the magnet 12.
  • each mechanism 24 includes a stationary body 28, to which is pivotably mounted attractor 22 at pivot mount 26. It can be seen in Figure 3a that the upright portion 30 of the attractor 22 is substantially vertical. In this position the attractor 22 lies directly in the circular path 20 followed by the magnet 12.
  • Arm 32 is pivotably mounted to the stationary body 28 at pivot point 34, and is pivotably mounted to arm 36 at pivot point 39.
  • the distal end 37 of the arm 32 contacts each of two oppositely upwardly sloping guide surfaces 40, 42 (see Fig. 6) and each of two oppositely disposed downwardly sloping guide surfaces (only one of which is visible) 44 (see Figs. 2 and 6).
  • the surfaces 40, 42, 44 form part of, and rotate with, the plate 14.
  • the magnet 12, plate 14 and shaft 16 are capable of substantially continuous rotation by virtue of the continuous interaction of the magnetic field of the magnet 12 with each of the magnet attractors 22. This is due to the associated continuous magnetic potential energy present because of the proximity between the magnet 12 and attractors 22.
  • a magnetic shield extends around the various sides of the magnet 12, apart from the side 48 facing towards the direction of rotation of the magnet 12.
  • the provision of the shield is highly desirable, as the magnetic attraction of the magnet 12 can thereby be at least partially limited to attraction to the attractor 22 immediately in front of the magnet 12 as it moves along the path 20.
  • the provision of a shield also limits the magnetic attraction of the magnet towards, for example, any magnet attractor 22 displaced (temporarily) to the side of the magnet 12 or any magnet attractor 22 that has returned to its position on the path 20 immediately behind the magnet 12, which may otherwise effect the desired rotation of the magnet 12, plate 14 and shaft 16.
  • the invention has been specifically (but not exclusively) designed such that movement of the magnet 12 along the path 20 actuates an energy output device 50 for outputting energy from the device 10.
  • the energy output device 50 may adopt any suitable form.
  • the output device 50 includes a mechanical to electrical energy convertor for converting the mechanical energy provided by rotation of the magnet 12, plate 14 and shaft 16 into output electrical energy by way of electrical generators 52 mounted stationarily in position.
  • the generators 52 include terminals 54, 56.
  • the output electrical energy may be utilized in any desired application, including personal, domestic, commercial and/or industrial applications.
  • the energy conversion device 10 may be scaled up or down for utilization in both small and large scale applications.
  • each generator 52 includes a rotating generator input gear 60, which is driven by torque gear wheel 62.
  • Torque gear wheel 62 rotates by virtue of it being mounted in position to (and rotatable) with shaft 16. Rotation of the shaft 16 causes torque gear wheel 62 to rotate, thereby rotating each of gears 60 so as to output electrical energy from the generators 52.
  • the energy output device 50 may be capable of storing at least some of the converted electrical energy by way of a battery (not shown) or some other suitable storage arrangement. This stored energy could then be later utilised to start, stop or otherwise control the device 10, if required. Indeed, the device 50 need not store electrical energy. It may instead store mechanical energy or some other suitable energy type.
  • FIG. 8 is a schematic plan view of a broad concept of an energy conversion device 1 10 according to the present invention.
  • the device 1 10 includes a magnet 1 12 surrounded by a magnetic shield 1 13.
  • the magnet 1 12 is a permanent, block magnet manufactured from a ferromagnetic material.
  • the shield extends about all sides of the magnet 1 12, apart from side 148, which faces towards the direction of rotation of the magnet 1 12.
  • the path 120 of reciprocating travel of magnet 1 12 is a linear path. As the magnet 1 12 moves close to each respective attractor 122, the attractor 122 is displaced sideways from the position 122a to the position 122b. Once the magnet 1 12 has passed the attractors 122 they then return to position 122a on the path 120.
  • the energy conversion device 210 concept shown in Figure 9 is similar to the device 1 10 shown in Figure 8, but instead of including a single linear arrange of magnetic attractors, two separate and parallel arrays 223, 224 of magnetic attractors 222 are provided. A magnet 212 and shield 213 are provided, which travel along linear path 220.
  • the present invention can be configured to supply energy for use in a vast range of potential applications, including the supply of energy to meet the requirements of small personal energy requirements through to large scale domestic, commercial, industrial and community energy requirements.
  • the present invention allows for a constant supply of energy, potentially requiring little or no maintenance and no recharging.
  • the present invention is not dependent on location, or environmental conditions in order to provide a constant energy output as is, for example, some sustainable energy sources like wind power, wave power and solar power.
  • the present invention is likewise sustainable and has no appreciable environmental impact.
