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.

.This is only a concept
Relation stator ? rotor: pulse motor: permanent magnets repelled by solenoid(s).
Solenoid works in two stages; since ferrite metals are always attracted by permanent magnets, the solenoid?s ferrite core will be attracted when power to it is OFF. When it approaches the critical point, solenoid?s power gets ON, to repel the magnet. The power to the solenoid can be as small as possible only for the permanent magnet to react on it., thus all repelling power relies on permanent magnet: solenoid in practice is only to switch ON into OFF and vice versa, even without switching current?s polarity.. Possible is however that solenoid will get powerful when ON, despite that it?s current remains small, by adding powerful permanent magnet to it?s (solenoid?s) extension without touching the core, on it?s farther side from the reacted magnet.
Result: the pair: solenoid ? permanent magnet (stator ? rotor) is not retarded by that adverse critical point area when the forces change form advantage one to adverse one (what is inevitable in relations permanent magnet ? permanent magnet), all using relatively small current. The minimal current needed to power the solenoid improves overunity ratio.
The difference from existing inventions is that those existing ones rely on permanent magnet?s power as well as SOLENOID?S power to interact; in fact, it gives more power but also diminishes overunity performance.
This approach is almost equivalent to Minato?s idea; the difference is in that permanent magnet added to the solenoid?s extension. However this kind of idea ( permanent magnet as solenoid?s extension to improve performance) also appears in some earlier inventions.

How do you wind up these toroids? It takes forever to wind those up with a few thousand turns....

Hi V  :)

You just find your favorite music cd, put the player on repeat, tape the workpiece to the table and
  start winding............................................about four hours later you wake back into
  consciousness and your neck hurts like hell........  nothing sophisticated here, hehe.    oh yeah
  here,s a tip, Don,t buy a rechargeable dremel tool, use a plugin, this will save you a lot of grief.

Self-induction. Excess-current

A conductor, through which flows current, lies always in a magnetic field - the field, aroused by the current. Every change of its intensity - including especially switching on and off - changes this field and the change of the field of force acts on the conductor, through which the current passes: It induces in it an EMF (Faraday). Because this induction acts back on the conductor, it is referred to as self-induction, and the arising current is called excess-current.

The excess-current is always directed so that it impedes the change of the current, to which it owes its generation (Lenz's Rule). For example, if you close a current or strengthen it, it does not reach immediately its full strength, or, if you strengthen it, it does not reach immediately its full intensity, but only gradually; the excess-current delays its growth; if you cut a circuit, the current does not vanish instantly; at sufficient strength, it creates at the point of interruption a strong spark - thus, the excess-current also delays the vanishing of the current. Self-induction is strongest when the conductor has many, densely spaced windings, all of which act in the same direction on the external field, like in the case of a solenoid (Fig. 542) and especially when the solenoid surrounds an iron core like in the spark inductor (Fig. 572), because it changes especially strongly the field of lines of force. You suppress self-induction of a coil by forming the windings as in Fig. 582, that is, bi-filarly. The windings then conduct the current in neighbouring windings in opposite directions so that their magnetic fields cancel each other. In coils with large resistances, their charge capacity nevertheless disturbs. In order to make it as small as possible, you wind coils from 500 Ohm upwards in the manner shown in Fig. 583: You wind narrow layers of of a few windings and change after every layer their direction.

Also, during self-induction, the magnitude of the EMF, induced in unit time, depends on the number of lines of force, intersected by the induced conductor during unit time. It depends on how fast changes the current strength, since the number of lines of force changes with the strength of the current. That is why it is much larger during opening of a circuit (opening-excess-current) than during closing it (closing-excess-current). In fact, during closing of a circuit, the arising current is impeded by the EMF of the self-induction; it rises only slowly from zero to its full strength, it has at the instant of closing the strength zero, but an instant later by no means the full strength. It is different during opening of a circuit. Immediately before, its strength is full, an instant later zero. For this reason, the EMF of the opening-current is many times larger than that of the closing current - it may be so large that it bridges the opening location by a spark in which the separated ends of the conductor melt. - The bridging extends the duration of the primary current, makes the drop (to zero) less steep and decreases thereby the induction tension of the current opening. Hence one lets in the spark inductor the electricity, which would discharge in the spark at opening, flow into the condenser, from which it escapes at the next closure into the circuit.

Moreover, the form of the conductor has great influence. If you use the same wire once stretched out linearly, another time as solenoid, and change both times the current equally quickly, the solenoid may have hundred times, even one thousand times larger induction than the straight wire. If you wind the wire bi-filarly into a spool, no induction occurs. Every coil, in fact, every conductor is characterized in this respect by the ratio between the EMF of the excess-current and the rate of change of the current. This ratio is the self-induction-coefficient; it is defined as that EMF, which is induced in the conductor itself, when the the current flowing in it changes in unit time by the current unit. If it changes in 1 second by 1 Amp and the coil is such (in form, length, cross-section and number of windings) that the EMF of the excess-current is 1 Volt, one says: The self-induction-coefficient of this coil is one (1) Henry. This measure is enormously large; in practice, you reckon with 1/1000 Henrys.
