I will repost what the back EMF looks like in case you missed it.

And how The current in the back EMF responds to a resistive load and an inductive load.

This is not the driving pulses because I am flipping polarities. This is the back EMF that is being separated that drives things with the hot terminal as the ground.

AWESOME!

So I tried the circuit in 2 ways and it runs just as predicted.  I got some preliminary readings and they look GREAT!

Obviously a load is needed on the DC side of the FWBR to complete the circuit. A capacitor alone as a load will not run.  But it runs fine with a resistor and a cap as a load.  Current was too jumpy to get efficiency readings.

Pay attention to schematic #2...  Use a DC Boost converter as a load..  Bring the boosted line to the source positive.  And I like what I see..

My source is using 17 volts at .9 amps..  Now the boosted wire has much higher voltage than the source + terminal..  And is sending 1.3 Amps back to the source!

Plus I got 3.6 Amps @ 16V flowing through the choke which is emitting a strong magnetic field I can feel with a ceramic magnet  18" away from the transformer core.

I am not saying This is Overunity like this..  The system is still taking 16 or 17 watts to run..  But I am pretty sure this is redirecting the Back-EMF to flow in the same direction as the forward Current. And it is giving me a leg that has Higher Voltage and More Amperage than the source..  Once I start tapping it for power things are going to change for sure..

I will post a video soon.  I need to organize this and get more data first.

EDIT-  If you don't understand how the circuit flows or works- I did a video going over the schematic here-  https://www.youtube.com/watch?v=S0XvYbj2b6c

For readers who do not understand how a choke produces back EMF. Not fly back, but back EMF exactly the same as a rotor.

Visualize on the image attached. Coil pulses south to the top. Iron core turns north at the bottom. Flux is directed to top of core.

Almost immediately when coil turns South at top, core is projecting north exact same as a rotor.

A choke can be viewed as a rotor running at almost 100% efficiency where the back EMF is neutralizing nearly all the the flux produced by the input.

This is why a transformer with its secondary disconnected will pull no amperage even though we have a direct short.  The back EMF creates extreme impedance which blocks input current from getting to the choke.

To be able to harness and separate this, the driving frequency must be lower than the choke is designed for so amperage can still be pushed through the coil to create back EMF.

This demonstration should be the nail in the coffin that Back-EMF of a coil can be introduced into the circuit from outside the circuit.  And we can send both the driving power + the back EMF in the same direction through a load..

We can send 20 volts  from a capacitor -->  through a choke and diode  and the capacitor settles at Negative 5 Volts!!!!

Meaning we can send out 20V to balance the Cap  PLUS an additional 5 Volts of Back EMF from outside sources through a load.

I watched your video 3 times so I was sure I understood what you were doing.  You need to understand how an LC circuit works.  When you discharge the cap into an inductor the current rises in the inductor according to the inductance of the coil.  Coils always resist change in current because of the inductance.  When the cap is fully discharged the inductor wants to keep the current going because of the inductance.  So in your case that inductor is actually charging the cap in the opposite direction or negatively in comparison to when you first charged it.  If you could control the length of time you had the cap connected to the inductor you could in fact recharge the cap to almost the same potential as you started with but in the opposite direction or negatively.  You just have to stop the cycle at exactly the right time.  If you had a scope connected to the cap and left the circuit connected you would see the cap recharge in the opposite direction and when fully charged it would discharge back the other way and recharge back in the positive direction.  The current will simply oscillate back and forth until the resistance absorbs all the energy. By the way that is not a good thing to do with an electrolytic cap.  With a high enough voltage you will damage the cap by charging it in the reverse direction.  There is no extra energy coming into that circuit.

You need to understand how an LC circuit works. 
The current will simply oscillate back and forth until the resistance absorbs all the energy.

Attached are scope shots of the circuit with and without a diode.

You are correct in a standard tank circuit with no diode.  But the diode prevents oscillations.
You are also correct that if you disconnected a tank circuit exactly after the first impulse before it can rebound back- you will get the same effect.

The diode does exactly that..  It stops the cycle so it can not oscillate back.  Now we can measure!  It sent the full 20V to the negative side to zero out, PLUS it picked up another 5V in BEMF that it also sent to the negative side.  Causing the cap to now be at -5V.

Please study the other image attached. Especially figure 3 and 4.  The exact dynamics can be seen and understood from those tests.  It clearly shows where those extra 5V are coming from.

Note- The cap with the yellow star is the source filled with 20V. All others are empty.  The values recorded is what each cap has in it after the circuits settle.
