the statement over unity is well a load of tests that no matter what you do is not proved
i mesure power in amps and volts not watts watts mean nothing amps do when on batterys we dont look how many watts we use we look at how many amos were using watts grid tied amps offgrid

   Guys:
  From what I've seen when charging a second battery from the run battery is that over time both batteries will get discharged, and will need an added bump charge to bring them back the their normal working voltage. 
  I have been working on this type circuit for a while now, but have not found that it is worth the effort. I hope to be proved wrong, as this is a very important point.  It would also prove that the Jtc outputs more than it needs to run.  But charging a second battery while using no other load like an led,  is not very interesting, or useful.  The led is the thief, so if any are used in the circuit for lighting, the Jt may not be able to overcome its draw, and still charge the second battery faster than it's draining the run battery, at least, when more than One led is used.
  If a solar panel is used to maintain a steady charge on the run battery this may not be the case,  otherwise it is a losing battle, as the run batteries will discharge, and will not be doing anything to charge the second battery. The process can last a while, yes, but not forever.
   A Jt circuit that can self-run and self charge and also put out some Usable light,  has NOT REALLY been made.  Or, If so, Can it be proven?
   Guys in black will not come knocking for such insignificant circuits that still use batteries that must be purchased.  Or will they? What are we trying to hide, the fact that we have NOT been able get this to work as we would like it to. 
  Lets get real,  or we'll be waisting more time. Time is one thing that we may not have too much left of,   before S*** hits the fan.
  What have we really gained with the the Joule Thief, Captret or Joule Ringer circuit? As they all still discharge their battery or caps.
Efficient, fun circuits,   but no cigar. 
 
   
 
                                         
   

 

CAT5 cable for the coil? I do the same thing

So, what tests have you run on this ?
