@Altrez,

WOW!

You started me down this path So thank you! If I had not went back to perform that test for you I would of went to bed!

OK Altrez.

These are re-posts.

Here is the drawing which may be easier to follow than a schematic (which may be wrong)
If there is room I also post a scope shot of this baby.

There are 3 sets of LEDS not drawn on this drawing.
1-the battery rail can be filled.
2-the bjt spot of the widow on the first tier has a led which is bright and draws a bunch of current.
3- there is another secondary/pickup from the widow which has 3-5 of its own leds.

That is how I set it up Monday and yes it works fine Great Job!!! Do you mind if I add that to my design?

Thanks!

If I read this correctly, the use of the neon as described sounds a lot like the way we use them in the Bedini circuits.  It is amazing to me how a lot of this stuff is connected in some way or another on here.  My neon on my no bearing one magnet Bedini (Jonnydavro's design) works in just the manner you said.  It is cool how a 120 volt neon can light very brightly and I am powering the circuit with a rechargeable 9 volt.  They tell me the neon is only there to protect the transistor. (2N3055)

That is interesting   

do  you have a schematic  of that  circuit ?   
I  didn't  have any idea that  the base of the 3055 could handle  that much  voltage .
I think  what I am  doing is alot like  some of the  Bedini  I have seen ........except he  used   bigger  coils
It seems to The  motor part  seems to be  optional ....  I have read that they  can still charge a battery  without the motor  part  running .



It is  nice to know that   others have  already  used  a neon  in a way similar to how I  planned on using it .......  I can often see how  things could work .....but  I am not  quite as good at actually getting them to work ....
I guess that is my problem


It is funny how sometimes  things  just start  falling together   
I was tearing old stuff apart  a while  back  looking for  toroids .
I  found  3055 on a nice  big heat sink
I guess it  will be one of my next projects

@all

Just explained the setup to a friend and he said that it was not working like I think? He is an EE and was in the Air Force for 30 years. He basically said the JT is simply a transformer and that a DC - DC converter is far more efficient then a JT when converting to DC?

Not sure about all that but I do trust him. He also said that I was not really charging the battery's at all? And that the voltage was empty?

Can anyone explain that?

Thanks!

Thank you Jim! It is very neat how we all seem to end up replicating each others work independently. It really seems to confirm the fact that there is so much more to this circuit then I thought before.

I have charged battery's and filled caps. I have pushed motors and lit neon's. I have even ran a 13watt CFL from a FUJI mode that was powered from a battery connected to a switch that is ran to my Main JT that is charged from a battery that is recharged from a different JT And this all can be done with out introducing any new energy into the system. All from the same battery's.

I plan on adding 6 charging points on my main setup with 4 2.9 inch Toroids connected to one main JT circuit. So far I am still running on the same set of battery's I started with on Monday. Adding a 50F SC to the mix soon that should push my efficiency up quite a bit.

The Cap will be in place to allow a fall off period for the battery's in separate tests I noticed that the battery's seem to have more power If allowed to rest for 1 hour or more? 

I still have a bunch of work to do. I do feel like this will keep on going as long as there is power in the JT. I took a battery from .900mV to 1.2 v in 12 hours. It normally takes me 5-6 hours to recharge from mains.

I plan on getting some of the 15 minute rechargeable battery's and pumping a Super Cap into them to see if they get a full charge. So at that point I will have the super caps charging the batters that are running the circuit that keeps the caps charged and also still run a DC motor, LEDS CFL with Fuji mod all from on circuit and a 1.2 v power source.

Take care!!!!

You seem to be making some serious progress here!  Keep up the good work
