I like the videos.
That last one with the 400 LEDs, were they connected in series as well just like the 300 were? 

Getting all this energy out of an AA battery,  WOW!
Just think what a D cell will give you. 
Now if we only had one of John Hutcheson's crystal batteries.
Maybe some one should email him about this forum.

The only thing that stops a carbon battery from working is the zinc plate gets covered in oxide so current won't flow anymore.
If you take the zinc plate and sand off all the oxide the battery will work again.
So a large open carbon battery with a large zinc plate easy to access could run this circuit for almost a life time.
This is the principle behind one type of earth battery, the rain and things in the soil keep the zinc plate cleaned.

Nice videos! Is that the same battery since the beggining without recharge?

What do you guru's think of this idea I have?

Should I begin by stripping down a small transformer, and use the transformer laminations to wind on some coils? or should I use a torrid instead? I'm trying to clear the cobwebs in my mind about this.

Attatch a reed switch at one end of the laminations to switch off the energy to the coil.
If I put several reed switches in series, this will stop most of the pit burning inside the reed switches to make them last longer.

Next feed the BEMF through a bridge diode, and feed this into another transformer to reduce the HV pulses back to Lo voltags pulses, then feed this back to my 1.5volt battery?

I know there will be others reading this and will say to use another method, but I think we could go in that direction "after" we have a working setup.

I am not a guru yet. I have not been able to get a decent feedback to the source.
But I know that you are a very good teacher and as so, you are also a good student. I know you can device something to get what you want.
If it is about transformers and toroids, the most indicated ones to help you are the others from the list you made.

@Mk1
Thanks for the wire gauge http

@ TheNOP
Thanks for the info as well you posted

@ all
Got to be at a grade 6 (my old school class mates) reception lunch, so I will be back in about 4 days from now.

There is sooooo much to catch up on, couldn't you lot go a bit slower? ha ha

This is what i use as a reference.

@Jeanna

the pickup coil will have the same voltage but more current goes true a big wire so more work can be done (more amps)
I would try making more turns on the 7 turns one.

If you are taking about the 3 pack magnet wire from radio shack , it 22,26,30 my 19 is bigger than anything radio shack got.
So far the green one the 26 i think is useless, 22 the biggest one is the best.
Smaller gauge are great to get real high voltages but real low amps.

18 gauge is the biggest Radio Shack sells around here.

    These might be a good substitute for leds but a bit pricey.  It pertains to my post about lighting an incandescent with high frequency instead of heating filaments to get high frequency.  Plasma is like a huge atom.  The ionized neuclei  stay at point a cause they're heavy.  The electrons takeoff and form an electrical current around a bunch of ionized neuclei.  It's like an element with an open end atomic weight and scale.  Some of the mass of the macroatom is converted to energy in the form of heat and light.  So basicallly in this bulb they are creating mass with emwaves and then converting some of that mass back into emwaves at a higher frequency than the input. 
   Sorry for the thread cloud but I thought you might find this new tech interesting.
