Muller Dynamo

[conradelektro]

the following circuit of a pendulum.
this circuit can run muller dynamo?
(sorry bad english google translate)

@d@rkenergy:  this circuit is exactly what I was looking for. The hall switches are not necessary, one can use the drive coil as a sensor for switching (as your circuit does).

I was using "trigger coil pairs" or "a single trigger coil", but your circuit shows that this is also an over kill.

One could sense the "drive coil" or "the drive coil pair" with a microprocessor which then adjusts timing and length of the drive pulse according to rpm (frequency of the sense signal).

I also agree with Oscar and Jason that LCR resonance is probably the key to understanding the ‘anomalous’ voltage or current relationships in the Romero and other similar devices.
 
However, it is important to understand the current amplification arises inside a resonant parallel LCR circuit whereas voltage amplification arises inside a resonant series LCR circuit (in both cases the amplification factor is the Q of the LCR circuit).

Furthermore, a current induced in a coil linked to a separate capacitor should be formally regarded as a series linkage notwithstanding any apparent parallel relationship between the coil and the separate capacitor (i.e. the signal source must be regarded as passing through the coil first then the capacitor, rather than through both in parallel).

However, if the capacitance is not separate but inherent in the coil, I am not sure how that should be interpreted as series or parallel â€" I would guess that it is a parallel relationship.
In the Romero design, the external capacitor is definitely in a series relationship to each generator coil (hence voltage amplification at resonance) whereas the inherent capacitance of the coil may be in a parallel relationship to each coil (hence current amplification at resonance).

Either way, the significant realisation may be that these devices represent a ‘mechanical’ way of extracting real power gain from LCR resonance (via voltage or current amplification). The traditional analysis of LCR resonance (whether series or parallel) is that there is a phase shift between the current and voltage at resonance so that the real usable power in the circuit (being the summation of the instantaneous voltage x amps) is limited. This is the same issue of real power versus apparent power (hence power factor) in typical AC circuits.

However, it seems in these devices that we may be making use of the current or voltage amplification in LCR resonance to extract corresponding mechanical power via a motor which then separately feeds back additional electrical power via a generator (with both motor & generator in an unusual ‘combined’ configuration) without having to face the consequence of the phase shift.  If this is the case, then we have essentially broken the constraint of the phase shift.

I must say that I am very old and staid in my outlook, so I still have a sense of unease in thinking like this!

Possibly an Ed Leedskalnin quote would be relevant at this point

" I made a lot more electricity with steel than I ever made with copper."

Where does the energy come from? When loading a tank circuit the quality factor Q is lowered, because energy is removed from the LC tank. A better place to look for the energy is in phase transitions. In a heat pump or refrigerator, which is a known over unity system, there is a phase shift in the working media (gas/liquid). The same applies to electromagnetic systems. Make a parametric change to the system and pump energy in/out from the surroundings. This can be done by driving ferromagnetic materials into saturation. By doing that it is possible to get a negative impedance characteristic. An inductor driven to saturation will lose a lot of its inductance. This is happening with the powerful magnets RomeroUK uses near the small ferrite inductors.

The energy content in an inductor (magnetic field energy) is given as:
E = ½ x L x i^2 where L is inductance and i is current. If the inductance decreases while current is running in the inductor the current will increase. It is like pulling out an iron core from an electromagnet. Work (energy change) is applied to pull out the magnet. This result in an increased current until the core is removed and the current settles back to the previous value. If both the magnetic field changes as well as the inductance changes there can be a parametric pumping. By studying the heat pump and the phase plane describing the parametric changes (Carnot diagram) it is possible to make an alike phase diagram describing a parametric inductor or capacitor and see how to remove electric energy from them.

It is like compressing or expanding a gas. But, instead of heat output it is possible to have a current as output when the inductance decreases in a magnetic field. Current increase = square root (Magnetic field energy / (½ inductance decrease)). This is the above formula solved for i with i and L changing.

I am doing that right now. I am creating a self tinning program. 
a fully functional OU device will need a computer to keep it a optimal performance.
