Gunderson’s Solid-State Electric Generator

Gunderson’s Solid-State Electric Generator shown in US Patent Application 2006/0163971 A1 of 27th July 2006.   The details are as follows:

Abstract
A solid-state electrical generator including at least one permanent magnet, magnetically coupled to a ferromagnetic core provided with at least one hole penetrating its volume; the hole(s) and magnet(s) being placed so that the hole(s) intercept flux from the permanent magnet(s) coupled into the ferromagnetic core.   A first wire coil is wound around the ferromagnetic core for the purpose of moving the coupled permanent magnet flux within the ferromagnetic core.   A second wire is routed through the hole(s) penetrating the volume of the ferromagnetic core, for the purpose of intercepting this moving magnetic flux, thereby inducing an output electromotive force.   A changing voltage applied to the first wire coil causes coupled permanent magnet flux to move within the core relative to the hole(s) penetrating the core volume, thus inducing electromotive force along wire(s) passing through the hole(s) in the ferromagnetic core.   The mechanical action of an electrical generator is therefore synthesised without the use of moving parts.

Background
This invention relates to a method and device for generating electrical power using solid state means. It has long been known that moving a magnetic field across a wire will generate an electromotive force (EMF), or voltage, along the wire.   When this wire is connected in a closed electrical circuit, an electric current, capable of performing work, is driven through this closed circuit by the induced electromotive force.

It has also long been known that this resulting electric current causes the closed circuit to become encircled with a secondary, induced magnetic field, whose polarity opposes the primary magnetic field which first induced the EMF.   This magnetic opposition creates mutual repulsion as a moving magnet approaches such a closed circuit, and a mutual attraction as that moving magnet moves away from the closed circuit.   Both these actions tend to slow or cause “drag” on the progress of the moving magnet, causing the electric generator to act as a magnetic brake, whose effect is in direct proportion to the amount of electric current produced.

Historically, gas engines, hydroelectric dams and steam-fed turbines have been used to overcome this magnetic braking action which occurs within mechanical generators.   A large amount of mechanical power is required to produce a large amount of electrical power, since the magnetic braking is generally proportional to the amount of electrical power being generated.

There has long been felt the need for a generator which reduces or eliminates the well-known magnetic braking interaction, while nevertheless generating useful electric power.   The need for convenient, economical and powerful sources of renewable energy remains urgent.   When the magnetic fields within a generator are caused to move and interact by means other than applied mechanical force, electric power can be supplied without the necessity of consuming limited natural resources, thus with far greater economy.

Summary of the Invention
It has long been known that the source of the magnetism within a permanent magnet is a spinning electric current within ferromagnetic atoms of certain elements, persisting indefinitely in accord with well-defined quantum rules.   This atomic current encircles every atom, thereby causing each atom to emit a magnetic field, as a miniature electromagnet.

This atomic current does not exist in magnets alone.   It also exists in ordinary metallic iron, and in any element or metallic alloy which can be “magnetised”, that is, any material which exhibits ferromagnetism.   All ferromagnetic atoms and “magnetic metals” contain such quantum atomic electromagnets.

In specific ferromagnetic materials, the orientation axis of each atomic electromagnet is flexible.   The orientation of magnetic flux both internal and external to the material, pivots easily.   Such materials are referred to as magnetically “soft”, due to this magnetic flexibility.

Permanent magnet materials are magnetically “hard”.   The orientation axis of each is fixed in place within a rigid crystal structure.   The total magnetic field produced by these atoms cannot easily move.   This constraint aligns the field of ordinary magnets permanently, hence the name “permanent”.

The axis of circular current flow in one ferromagnetic atom can direct the axis of magnetism within another ferromagnetic atom, through a process known as “spin exchange”.   This gives a soft magnetic material, like raw iron, the useful ability to aim, focus and redirect the magnetic field emitted from a magnetically hard permanent magnet.

In the present invention, a permanent magnet’s rigid field is sent into a magnetically flexible “soft” magnetic material. the permanent magnet’s apparent location, observed from points within the magnetically soft material, will effectively move, vibrate, and appear to shift position when the magnetisation of the soft magnetic material is modulated by ancillary means (much like the sun, viewed while underwater, appears to move when the water is agitated).   By this mechanism, the motion required for generation of electricity can be synthesised within a soft magnetic material, without requiring physical movement or an applied mechanical force.

The present invention synthesises the virtual motion of magnets and their magnetic fields, without the need for mechanical action or moving parts, to produce the electrical generator described here.   The present invention describes an electrical generator where magnetic braking known as expressions of Lenz’s Law, do not oppose the means by which the magnetic field energy is caused to move.   The synthesised magnetic motion is produced without either mechanical or electrical resistance.   This synthesised magnetic motion is aided by forces generated in accordance with Lenz’s Law, in order to produce acceleration of the synthesised magnetic motion, instead of physical “magnetic braking” common to mechanically-actuated electrical generators.   Because of this novel magnetic interaction, the solid-state static generator of the present invention is a robust generator, requiring only a small electric force to operate.

    I blog often and I seriously thank you for your information. This great article has truly peaked my interest. I will bookmark your site and keep checking for new details about once a week. I subscribed to your Feed too.

  3. I must show thanks to this writer for rescuing
    me from such a crisis. Just after researching throughout the the net and obtaining tips that were not helpful, I thought my entire life was
    over. Living devoid of the approaches to the difficulties you
    have solved as a result of your good short post is a critical case, and those which could have in
    a negative way affected my career if I hadn’t noticed your web site. Your main mastery and kindness in playing with all the pieces was helpful. I’m not sure what I would’ve done if I had not encountered such a stuff like this. I am able to now relish my future. Thanks a lot very much for your skilled and results-oriented help. I won’t be reluctant to
    propose the sites to any individual who needs tips about this topic.
