Holcomb Energy Systems:Breakthrough technology to the world

@pmgr
All true , but how this would apply for Holcomb?
Tesla did modified homopolar generator, where you have stationary magnetic field and rotating disc.
The only thing Tesla did was enlarging stationary magnet to cover whole rotating disc ( better efficiency) and cut disc into sections , avoiding circular currents because the only current path we are looking is fron disc centre outwards. Tesla was perfectionist.
In Holcomb we have rotating magnetic field ( from 3 phase motor armature)and some exotic explanations regarding unpaired electrons inside ferromagnetic material.
What striked me most is his "discovery"  that ferromagnetic material amplifies weak magnetic field acting upon it.
Primary school pupil is teached about it.
This rings a warning bell in my head about Holcomb.

Please read the attached European patent application from 2019 which on page 8 describes the mechanism for the excess energy.


The summary of it is as follows:


He uses rotor coils to align the magnetic domains inside of the electrical steel and he says that the energy required to do this is little. The generated magnetic flux from the aligned domains is however much stronger (and carries much more energy) than what was required to polarize the magnetic domains into the right orientation (e.g. a north or a south pole).


The stator then converts this strong magnetic flux into a voltage/current that can be used to power a load and part of the stator output can be fed back to the rotor driving electronics to provide the little energy that was required to align the magnetic domains to either a north or south pole.


So basically he is saying, he is magnetizing electrical steel to form a north or south pole and this north/south pole, once formed, can provide more magnetic flux than the flux of the current that was required to align the magnetic domains.


Any physicists that can shed some light on whether this is possible? From everything I know, it takes energy to magnetize a piece of steel and to demagnetize it or flip the magnetic domains in the other direction. I have never seen a piece of steel being magnetized and the magnetic strength being larger than the magnetic field that was generated by the current that magnetized the steel.


And if this were really the case, why don't we see this with a regular transformer? Also, there should still be BEMF from the stator coils working back onto the rotor coils, just like in a transformer. Maybe after the rotor current is switched off, the steel will remain magnetized for a short period of time, but the BEMF from the stator coils would oppose that magnetization and try to flip the magnetic domains in the other direction.


Please post your thoughts...

Those kind of things you should hear in primary and secondary school at physics lessons.
1. It is well known that ferromagnetic materials greatly amplify magnetic field acting upon them. It is called magnetic relative permeability.  Please see attached magnetising curve of soft ferromagnetic material.
2. As you could see on this graph, first part of it, vertical is nonlinear and a weak external magnetic field 0.1-0.2mT creates a strong response inside ferromagnetic material 1000-1500mT. Further to the right magnetization line is going more horizontal- this is called "saturation" area. Increase of external magnetic field causes less amplified response from the ferromagnetic material. This "saturation" region is a place where common transformer works.
3.Relative Permeability of certain magnetic material gives you amplification  of applied external magnetic field. For example for an iron core it is 200, for a permalloy it is 8000, for mumetal it is 20000.
4. Magnetic field amplification by ferromagnetic materials , or "gain" is  widely utilised everywhere: in electromagnetic solenoids, in Current Transformers, in Flyback and Boost converters ect.


So, my friend. Holcomb didn't invent anything new. This is a basic physics knowledge at least from a two centuries.

No, Holcomb didn't invent magnetic field gain. If he's for real then what he has invented is a way to utilize the magnetic gain without reflecting the load back to the primary windings.

I've spent this last winter experimenting with gain from magnetic flux. I can tell you this much, gain can be had by avoiding counter emf (Lenz) produced by secondary windings during the magnetization phase of the core primary windings. Ordinary transformers and ordinary generators do not do this.

Who is saying that transformers or generators are doing this?

Flyback converter is doing this.
Boost converter is doing this.
Joule Tchief is doing this .
