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

[Pirate88179]

I like the idea of substituting supers caps for the battery.  Then, since caps do not generate electricity, power measurements should be easy to do.  I don't know who proposed this idea but I like it.

I have check again my gadget at my room where the led still lit on (24 hours, never turn off).
I've been make mistake on drawing schematic as i post before.
I attach the new schematic according the gadget acctually. Change on BC 549 , swap emitter with collector.

Now, i ve measurement of current at point P & Q,  at P  -->  1 mA and at Q  --> 6 mA.
Maybe . is it the answer, why the led will lit on for long-long time.

Anyway with charging system schematic, i got benefit for revive my used NimH battery.
Now, that battery can be charging with ordinary charging and storage well

@Zon,
what advantage has it to run the transistor the wrong way around ?
Still drawing 6 mA from the battery and only 1 mA going into the LED ?
So what is the efficiency ?

@hartiberlin
i build that gadget for first time, purpose to make the longest time to light LED with single AA battery and a few component.. 

and now , i continoue eksperimen  to get efficiency and "something".

i got a clue from my friend, who already make gadget. "Oscilating minimum 30 Khz  to maksimum 350 Khz (100%)"
but he don't want sharing to us what exactly what he make it.
I'll do the best  i can and get some clue from him

Lol thanks Bill

Indeed, by switching the batteries for capacitors, power measurements
should prove a lot easier.

@Feynman: Well, there are some characteristics of the Bedini tech that you could
check for...
One of the things regularly mentioned by people who have built or experimented
with Bedini motor/chargers is that the batteries that are charged using the
"negative energy spike"/"back emf pulse"/"RE pulse" whatever you want to call it,
often just die after they have been used for a while. When such a battery, that
no longer accepts the "negative energy spike" charging pulse, is connected
to a normal grid-powered battery charger, it "eats" or "sucks up" a lot more
electricity than it should be able to hold.
Some accounts describe how the battery was charged for a couple of hours,
using electricity, but it remains "flat" for a long time, and only after a multitude
of the normal charging period will it start to accept and hold charge again.
I have been told this is an effect that can be caused by "deep cycle charging"
of a battery, and in relation to this it has been suggested that Bedini "merely"
deep-cycles his batteries using hV pulses, but does not actually harness any
"radiant energy" at all. That interpretation comes down to it being a sort of trick,
that somehow "jolts" the battery into depleting itself chemo-structurally,
thereby giving up electrical energy that it would not give off in normal operation.
Or at least, that seems to be the only viable explanation for a battery first
seeming to churn out more energy that it normally should, only to suck up a lot
more energy than it normally should too...

That said, there is a variation on the theme.
This is the "splitting the positive" approach that uses capacitors (instead of
batteries; the "normal" "splitting the positive" approach also uses batteries).
I believe on of our fellow forum members here worked on that for a while,
and I'm not sure but I seem to recall he claimed some limited success
using only caps.

In any case, I think making a capacitor-only version would be the best
test, and the best way to minimise measurement artifacts.
