Re-Inventing The Wheel-Part1-Clemente_Figuera-THE INFINITE ENERGY MACHINE

Gyula,
That was a very inspirational piece of info. so inspirational I'll add it here:

" Although the air gap has a volume of only 1.1 percent that of the iron, it stores 24.4 times the energy stored in the iron. However, as the iron becomes saturated its permeability decreases and the ratio of the energy in the air gap to that in the iron also decreases..."

What about the saturation of iron core in the form of  straight  bar ?

[RandyFL]

my take on saturation...
Professor Figuera probably understood saturation...
maybe saturation is alleviated because of the way it enters the 7 transformers...
I would imagine that the resistors ( wires that He used ) got extremely hot----------->maybe to heat up water or coffee :-) 
my results were quite scientific....the BDX53 s ( power transistors that I used ) were measured for heat.........by my fingers LOL
I didn't use heat sinks because I could disconnect the power easily.......

I am going to do a rebuild of the circuit ( with Heat sinks and lower Ohm resistors ) soon...

Forest,

" In electronic circuits, transformers and inductors with ferromagnetic cores operate nonlinearly when the current through them is large enough to drive their core materials into saturation. This means that their inductance and other properties vary with changes in drive current. In linear circuits this is usually considered an unwanted departure from ideal behavior. When AC signals are applied, this nonlinearity can cause the generation of harmonics and intermodulation distortion. To prevent this, the level of signals applied to iron core inductors must be limited so they don't saturate. To lower its effects, an air gap is created in some kinds of transformer cores "

Hi RandyFL,

I think it is a good step to isolate your iron cores with paper or paint as a first step before jamming them into the coils, this helps reduce eddy current loss in the iron.

Yes, to reduce losses of all kinds we tend to increase the overall size or volume of transformers but for testing purposes one should decide about the sizes as per his means make it possible. You are to decide as per what you can afford, no need to go for extra large or small sizes, the most important is to reduce eddy losses what you already correctly decided.

On Woopy or Kehyo: perhaps a kind inquiring personal message to each of them could bring you answers?

On the quote you repeated from the link: please keep in mind that it is the input energy which supplies BOTH the magnetic energy in the core (or coil) and the magnetic energy in the gap. It is fortunate that in the air gap (which is made in an otherwise closed magnetic circuit) more magnetic energy can be found than in the core, the sum of the two energies makes up for the total input, (minus the losses).

to Forest:

A straight bar or I core has an 'infinite' air gap around it so it is hard to excite into saturation. Of course it can be done, a mere question of AmperTurns.
However, when you arrange straight bars close to each other, conditions for saturation may change, depending on how the magnetic circuit can develop towards a possible closed or closed-like  circuit, and in this case you can reduce saturation by decreasing input current, either by reducing input voltage amplitude by a Variac or connecting one of the input wires to a tap on the input primary coil (if you provided some taps beforehand, that is).
