Sam, have you started the magnetics yet?

when using an inductor in an AC situation the currant change causes the change in flux thus the change in C emf (lenz Law)(reluctance) to the original currant flow. i hope you know this as this is basic inductor theory.
so if we use DC that is steady currant something has to change to get the magnetic flux to change in intensity in order to get currant reduction. so think how can you get the circuit to change to change the flux intensity??

And i quote; "Any alteration to a circuit which increases the flux (total magnetic field) through the circuit produced by a given current increases the inductance, because inductance is also equal to the ratio of magnetic flux to current."

so by adding a rotating positive brush the circuit is being altered on a continuous basis. by adding more winding to one side of the brush as it rotates, this alteration is changing the magnetic flux to currant ratio increasing the magnetic flux which is the opposition to the original currant flow, C emf reducing currant flow. while on the other side of the brush the alteration to the circuit is decreasing in size thus the ratio of magnetic field (flux) to currant  is decreasing which will cause an increase in currant flow.

what Figuera did was take a static inductor and used it as an active device which blows everyone's mind all to hell. by doing this it allows the magnetic field in the inductor when reduced, releases the reduced part of the field into the system to off set the potential drop of the rising side of the system.
it is a physics fact that all magnetic fields when raised will cause a potential drop across the conductor so if one was using basically two sets of primaries one increasing and one decreasing, one set will be releasing some potential into the system and one will be storing into the magnetic field causing a potential drop across that conductor. so if you have two sources of potential being released into the system that will off set the potential drop of the rising side through amplification. the secondary is added to the mix to give the added amplification to the rising side and replace the losses occurred through heat, core and wire losses.

i hope you can understand what i has just conveyed to you. read it a few times if you have to, it will eventually sink in, or not. all Physics facts not fiction. just because you may disagree with what is said does NOT change the truth, Physics are Physics and can NOT be disputed only ignored.
argue all you want but facts are facts backed by Physics not pipe dreams and what if's.

Sparkmen -  You are welcome. I intend to start the magnetic portion when I have the time and cash on hand to do the entire thing.

Iflewmyown  - See above.

Thank you for your observations, especially the one that says that in the original Figuera device some regeneration may occur and thus reduce losses. This is different from an electronic exciter where the two exciter circuits are not physically connected, and direct energy transfer back and forth between them is not present. Since the energy is being drawn from the environment and costs nothing, a small loss is unimportant so long as it does not become excessive or cause functional problems.

Since the electronic circuit does not employ resistors or other devices driven by a DC voltage, those losses are not present. So which device has the greater loses? I don't know, and can do nothing about it anyway. Moot point.

Sam6;

Thank you for being civil by the way.
i hate to be the bearer of bad news but electronic circuitry can not store and release the needed potential of the reducing side to amplify the potential to the rising side. sorry but this will not take place and therefore the device will be no better than a standard transformer if you have to supply the full amount of potential to the primaries every time. it does not matter if the losses are reduced using electronics if you have to supply all the power all the time to them, so what is the point.

part G's inductive qualities are there for a purpose, when reduced,  it releases that reduced potential from part G, the primaries and the added secondary to give amplification to the rising side of the system.

electronics can't do this in any way shape or form so the least you can do is a mix of the two. having a core and electronics to mimic the rotation of the brush otherwise you are stuck with a transformer.
sorry but this is hard fact reality check and can not be avoided.
