Feedback To Source

My goal here is to run a motor with a 1.5v or 9v battery and charge the battery while running the motor.

The question is:
If I have a circuit, like the camera circuit, that increase the source voltage from 1.5v to 12v, How I can feedback to the source battery without conflict between the two different voltages?

Here is a simple thought. (probably too simple)

If the source battery is 1.5 vdc and your circuit ups it to 12 vdc, why not feed that to 8 1.5 vdc batteries in series so they add up to the upped source voltage?  Then you would not need anything to step down which would create more losses.  Once the 8 1.5 bats are fully charged, pull out one and use it for the source and put the first one in the series of eight.  Actually, you could do this with a simple switching set-up.  Tie all 8 bats in series but have a lead to each one so you can select any one of them and also include the source.  I am not explaining this right but basically, Bat 1 is the source, bats 2-9 are the destination.  When ever you want you can make bat 2 the source and bats 1, and 3-9 are the destination.  This is sort of what I have been thinking about.  At first, I would use manual switching but later, after you have established that this works (IF) then you can make an automatic timed switching network that would select the appropriate bats at the correct time, once you know when/how often, this needs to be done.

Probably a crazy idea but, when I first started making my Bedini SG motor, this is what I always wanted to do.  I have not finished my motor yet, I keep getting sidetracked by other interesting but related things.

Great topic by the way.

Thank you @pirate

Here is another piece of the schematic as it is working right now.

Even though only a few responded to this thread, the whole thing is this:

Happy holidays!

@ Jesus:

You have this running right now?  How is it working?  Or, are you still building it?  If you have the ability to make a video or post some pictures, I would love to see it, even if it is not completed yet.  I can sort of follow schematics for the most part but, to me, there is nothing like seeing it in 3d.  What type of motor are you using?  There are some very efficient and very powerful dc motors out now for things like the RC market and robots.  These motors did not exist 15 years ago to my knowledge. I can't wait to see what you have.
