AC from Joule Thief Secondary/pick-up

[jeanna]

This sound very interesting to me and looks to be the right direction to be heading.  When you say back to the source is this being done on a secondary=rectified into a battery or cap. while the primary AC is used and changed to power a load?

Well, this is a tricky one to answer.
The short answer is no, that is not what I mean by back to the source. I think ac has inherently a back to the source built into it. It is a hunch. I want to experiment with it.

Please let me use a water metaphor.

Compare Niagara falls(DC) with the ocean(AC).
They are both very powerful.
Rectifying and returning the energy to the source battery is akin to hauling all the water from the lower river back up to the lake so it can fall over the turbines again.

I believe we have never explored how to use the ocean.

We might scoop up a funnel full of water and use its energy as it falls through the bottom the way we do with the falls, but we do not work with the moving waves in their powerful oscillations.
The ocean is powered by cosmic forces.
Not a mystery, just very large and beyond our local walls.

I think Tesla was discovering this and he left hints.

He was strapped by the need to use sparks to produce oscillations. As I have said before, happily, we have the transistor.

@All,
I have just made a pair of drawings that may help explain what I am up to and why I used the Tesla drawings.
They are the beginning of a larger study so I am calling them study 1a, 1b.

This is new territory for me, and I am enjoying the prospect of discovering what this is about.
I appreciate any help or company in this effort/play.
And, of course, what you may want to set up may be quite different from what I do.
Just, please, if you want to rectify the output and put it into a cap or battery for later use, use the main joule thief thread next door for that.
You will get a lot more supporting company there anyway.

tesla wrote an article relating this phenomina to water hammering in plumbing where all the tension is even at all points along the line at the same time stating that the speed was more inportant than the volume of flow but the secondary volume must be concidered for the pressure rise. caps may be soften this effect in the secondery circuit.

There was this forum member asking me this question:

I am not too good at drawing circuits, and I want to ask you how it is that there is no direct line that goes to the battery from the emitter of the basic jt transistor?

I will answer it here so any other member that has the same question can benefit from the answer.  Please correct me if I am wrong.

The battery is not connected directly to the base of the transistor because the winding that comes from the JT to the base called the trigger, is the one that provides the positive working voltage.

The battery positive is connected to the center tap of the JT and it is divided into two positive signals, one directed to the transistor's base and the other to the transistor collector....

But it is.
The Emitter is connected to the neg of the battery.
I doubt if I will EVER forget that one! 

Jesus, He didn't say the base did he? I think he said Emitter???

Oh dear,
The lights keep going out.
Maybe this is fussy.

I put a known jt - the widow- with 2 secondaries in the basic spot.
I am using the larger secondary for now.Without any load on this secondary the volts reads 32v peak to peak.

It readily lights up 4 leds in series and still shows around 24volts across the secondary leads.

So, I put a toroid wound with 2 wires into this.
The fewer wires are in the spot parallel to the leds etc, and the more wires free to be transformed up.

But when I put the new transformer into the pins, the lights go out.. If I move the transformer over one light, then only one light goes out and the voltage remaining has dropped from  24 to 3.5v or even less.

?? ??
Is this normal behavior for a transformer?
