Single AA battery to light WHITE LED for long-long time

[zon]

It's another my experiment. Another version schematic based on i post in http://www.overunity.com/index.php/topic,3599.msg80317.html#msg80317

Single AA battery to light white LED.
Until now (more than 96 hours) still light on without "reducing" power of battery.  I'll keep it on until the battery dead but  i hope it will not. 
I revised the original schematic, change diode from 1N4007 to 1N4148. I think is a best. Thanks for newton2 for your comment.

And now i have 2 circuit, i'll keep eye on it.   One with 1N4007 and  new on with 1N4148.
Same Battery using AA NiMh, 1.2 V 900 mAh.

Attachment is original schematic, please change 1N4007 to 1N4148

That looks to me like a Bedini style circuit, and I know because I've built my own "Bedinified" version of Joule Thief. I did not use a toroid core but a ferrite bead with 20 turns of AWG 30-34, bi-filar wound.

You can do away with the 1N diode and the capacitor, they are not really necessary, remember LED is a diode...

The issue I have with these circuits is that they appear to be good for a single LED and 1.2-1.5V battery source only. I hoped to extend them into driving 30+ LEDs from a 3V-6V source, as brilliant as possible, without much luck so far. I tried winding different configurations of coils, even used RStiffler's SEC driver and AV plug, yet brilliance is nothing I want to use as a normal light replacement.

Yup, my schematic get inspiration from "make a joule thief" and John Bedini "Simplified School Girl Circuit" and the principle that charge is not consumed but wasted in conventional electrical circuit as mention in "free-energy plans"  look at http://www.opensourceenergy.org/Portals/0/NTForums_Attach/Free_Energy_Plans.pdf .

"Make a joule thief" is a classical circuit, DC-DC converter, where is a cathode of LED connect to ground (-)     It will drawn the battery source.

My diagram combining with bedinied to get "radiant charging" effect where is a cathode of LED connect to  + .  and i put capacitor 470 uf for storage.

@Amigo
Diode must be there, without diode the led will not light on.
Right, this schematic only for load 1 led and "charging" battery type, like NimH, Nicad etc
I try load more led in pararel, and drawn the battery source in certain time.
but if you put led on serial (I have tried with 5 leds) the battery source will not drawn.

@all
Actualty, i don't understand with this phenomena.  I don't have electronic bacground only hobby using bread board    and measurement tool using only WOA Digital Multimeter.

Maybe someone could explain to me what happend to it.

Until now the two circuit that i have build still light on and  battery power not drawn at all.

I built a simple voltage-regulated driver circuit to run a pair of high-intensity leds off a single 9v battery for an art installation last November.  While taking down the show, I decided to leave the circuit running to see how long the leds would continue to glow.  Well, it's March now, and the leds are still lit.  Not super-bright, but still quite visible, even in broad daylight.  They have been putting out a flux of photons 24/7 for 4 months, and they don't seem to be getting any dimmer.
