PhysicsProf Steven E. Jones circuit shows 8x overunity ?

  Radio Shack is world wide,  at least here in Costa Rica there are several of them. They do have red, and white, leds of several sizes. so it should not be a problem to obtain them in many places in the world.

@ NickZ

run time in hours = (battery mA-hrs) / (circuit battery drain in mA)

Most AA batteries are about 2000 mA-hrs. Therefore my 0.01 mA circuit should run about 2000/0.01 hours on one AA battery (which is about 22 years).

   Xee2:
   22 years huh?  And what do you get as far as light with .01 mA draw. Do you have a picture of it?  Please refer us to your diagram or info on it.
   Like I said I'm really not too concerned about the efficiency, as my cells are providing even more than 22 years worth of light for free.  I may not live that long though.  But, I am looking for usable light, not just a boringly dim led, that has no purpose,
   My purpose is to light my house for free, and I'm getting there, without paying for it.  But, I do feel that there is a chance of creating a self-runner also, but one that works, and give a useful amount of light. Not a toy.

   Kooler's BwJt has 70 leds lighing off of one AA.  (brightly)...  But,he doesn't say for how long.   He mentioned that he's built over a hundred of these circuits.  One of these days he'll feel better and will speak for himself.
 
  Yes, I know that some of you have built circuits that last a while, and I also know that you need to use best core to get the best results.  The correct winding on the core is what going to make it or break it.
 
Hopefully this is not just like the Joule Ringer or TPU which nobody can replicate.

... what do you get as far as light with .01 mA draw.

Very dim light and batteries do not last 22 years. Circuit was posted a few pages back. Reduce base resistor value to increase LED brightness (and increase battery drain). 2 mA can give bright LED, 20 mA can give many very bright LEDs. Read through Joule thief thread and you will find a lot of info.

RE: the video smart_scare_crow
let's use a thermal wattmeter,  I agree, I think this is progress
when everybody has one of these there will be enough data
to create the kind of catalyst necessary to really take off.
