Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Hi Jimboot,
Current plays a big-time role whereas frequency isn't even mentioned. Often confusing.... Strength, intensity, density, and so forth.
Encyclopaedia Britannica does a decent definition. Copied and pasted for your convenience.

Alternate titles: magnetic field intensity, magnetic intensity
By The Editors of Encyclopaedia Britannica • Edit History

magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization. The magnetic field H might be thought of as the magnetic field produced by the flow of current in wires and the magnetic field B as the total magnetic field including also the contribution M made by the magnetic properties of the materials in the field. When a current flows in a wire wrapped on a soft-iron cylinder, the magnetizing field H is quite weak, but the actual average magnetic field (B) within the iron may be thousands of times stronger because B is greatly enhanced by the alignment of the iron's myriad tiny natural atomic magnets in the direction of the field.

magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field. Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism.

Around a permanent magnet or a wire carrying a steady electric current in one direction, the magnetic field is stationary and referred to as a magnetostatic field. At any given point its magnitude and direction remain the same. Around an alternating current or a fluctuating direct current, the magnetic field is continuously changing its magnitude and direction.

Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense. Farther away, where the magnetic field is weak, they fan out, becoming less dense. A uniform magnetic field is represented by equally spaced parallel straight lines. The direction of the flux is the direction in which the north-seeking pole of a small magnet points. The lines of flux are continuous, forming closed loops. For a bar magnet, they emerge from the north-seeking pole, fan out and around, enter the magnet at the south-seeking pole, and continue through the magnet to the north pole, where they again emerge. The SI unit for magnetic flux is the weber. The number of webers is a measure of the total number of field lines that cross a given area.

Magnetic fields may be represented mathematically by quantities called vectors that have direction as well as magnitude. Two different vectors are in use to represent a magnetic field: one called magnetic flux density, or magnetic induction, is symbolized by B; the other, called the magnetic field strength, or magnetic field intensity, is symbolized by H. The magnetic field H might be thought of as the magnetic field produced by the flow of current in wires and the magnetic field B as the total magnetic field including also the contribution made by the magnetic properties of the materials in the field. When a current flows in a wire wrapped on a soft-iron cylinder, the magnetizing field H is quite weak, but the actual average magnetic field (B) within the iron may be thousands of times stronger because B is greatly enhanced by the alignment of the iron's myriad tiny natural atomic magnets in the direction of the field.

Bistander,

Great research find - thanks for sharing! Cohesive and comprehensive and from a known authority.

Appreciate it. Nice work...

Friends, I will say this: who owns the technology of electromagnetic induction? Who owns the rights to the alternator idea?
As soon as you publish the scientific justification of the technology based on the laws of nature, no one will forbid you to design and build generation devices.
Here we have individuals trying to push free energy device technology (OverUnity) into the realm of interest rates.
I will disappoint them, your interest on the loan will not work as soon as the technology is released to the public.
Generators are designed and manufactured worldwide. Neither company discloses the details of their developments, only the general formula. I repeat, you will have to delve into many disciplines, and this again means costs, time for scientific and engineering research.

Holcomb does not own the rights to the theory of electromagnetic induction or the discovery of the magnetic properties of electrical steel, bismuth, mu-metal, etc. (ferromagnets, diamagnets, paramagnets).
His technology provides for the use of this public knowledge in his technology, which is partially (without details) disclosed in his patents.

There was a dispute. Does Holcomb's technology work?
If anyone doubts, I want to ask you personally contacted the company, what was your answer?
A published energy report for a commercial facility where Holcomb systems are installed is not a declaration, but a report.
For a specialist, this is enough, but for a non-specialist, you just need to reach the level of a specialist. In other words, improve your knowledge.

Fab it at your local shop - put up a solar panel - and blame your reduced power consumption on the panel!
Share it with your friends and neighbours...  :)

Remember - I know nothing - a guy showed up and did some solar work as far as I know - I wasn't home!

I'm meeting with a local fabricator to discuss rotor laminations to fit my stator. I'm looking at the easiest avenue for my neighbours to replicate. If they can can take an old generator stator and fashion a new rotor, we can work out out switching later. ( And ay rand Ay rand so far away.  Who is John Galt?)

Jimboot, et. al.

Anyone know of an off-the-shelf 5KW or so Generator that would work for this? I like Jimboot's approach but will have to purchase
a COTS (Commercial off-the-shelf) unit. Preferably with a built-in Inverter. Not going to modify my current back-up until Hurricane
season is over.

Jimboot - if you want to share your Processor requirements (number of poles, etc.) I'll add it to the ST Microelectronics design. Board I'm
developing is somewhat expensive (STM32xxxx Discovery ~ $75US) but it's got a small (4") LCD and lots of I/O and other features.
Trying to port the Flowcode "C" over to it is a bit challenging however (for me anyway). Hope to be freedup soon so I can finish it.

SL,
If you're interested in COTS (commercial off the shelf) stator to produce a RMF (rotating magnetic field), I recommend a high efficiency NEMA 3-phase induction motor. Pair that with a good quality VFD (variable frequency drive) and you're good to go. Your choice for 2, 4, 6 ... pole. Can easily press out shaft and build own 'rotor' on it and lock it in place with simple bracket. Costs on motor and VFD should be very reasonable. New surplus name brand equipment are available on eBay and such.

If you can locate a reasonable cost slip ring induction motor, that would give you a rotor with slots which you can strip and rewind.

Nothing wrong with using a generator (alternator) but you'll pay a lot more more, IMO, and the stator winding will be the same.

If you're willing to do the legwork, visit motor rebuild shops in your area. A great resource. And personnel love to talk about their craft, from my experience.

Good luck.
