Is joule thief circuit gets overunity?

Use the inductive spikes in the battery again:

you can try charge a large series of many bats DIRECTLY from the bakspike yes,remember the bakspike is many times more voltage than 4ward spike and many times less current than 4ward spike thus we have to capture as much of its POWER(VI) as possible,seperately from the power source(single 1.5v cell).then when power source runs flat we take all the series recharged(all seperate 1.5v same size) cells and put them all into parallel and then compare if its now more TOTAL power captured than spent by source. 

[profitis]

in other words,my scientific angle here is to capture and then store the accumulated totality of any excess overunity power BEFORE re-using it because if you use it while generating it you will be losing valuable power thru downstep transformers,l.e.d.s,bla bla bla.i bring into question the amount of power lost at the rectifier/diode itself even,probably enormous losses there.

the back emf spike off any inductor is many times faster than any forward oscillation spike,how can anybody accurately assess the totality of power of this backspike?it happens so fast that it screw-hysterises any measuring meter im sure.its absolutely essential to accurately asses the total wattage of each spike to get a clear picture of totality of spikes no?possible with todays scopes?

I don't know that your statements about the back spike are really of concern when making measurements on a  joule thief circuit with a LED connected as a load. The LED limits the back spike peak amplitudes to the forward voltage drop of the LED, and the frequency of operation is relatively low, so these spikes appear to be readily measurable with even a lower end scope. If you are not referring to a joule thief circuit with a LED as a load, then it could well be a different scenario depending on circuit specifics. Of course a lower end scope will not be as accurate as a higher end scope overall, but as long as any given scope is used within its particular limitations and the scope is calibrated correctly, the measurements should be suitable for getting a reasonable idea of the efficiency of a joule thief circuit with a LED load.

Now that we understand the significance of crossing the 0 ref line, I decided to go back to the old demonstration boards with an additional winding on the toroid.
Sure enough, I detected the crossing of the 0 ref line by the Output Voltage!  This gave rise to very low Output Power or even negative   However, many LEDs can be lighted brightly.  Shall investigate this more.

Hi Lawrence, I am not so sure that you do fully understand the significance of zero crossings. Zero crossings are normal with any AC waveform, but such zero crossings in no way necessarily suggest that there is anything unusual going on. I think your biggest issue to date is that you are sometimes attempting to draw conclusions about different things that you see without first trying to take steps to fully understand what is happening. Adding a secondary winding will cause you to measure an AC waveform with zero crossings from the secondary winding, but a LED will only conduct current in one direction, so one half of the AC waveform will cause next to no power consumption in a LED. Not sure if you are using a LED or LEDs as a load?

Some things that you seem to be seeing as unusual, are really just very ordinary things which are easily understandable and explainable by someone with even just a basic electronics background. For example electrical noise pickup in any electronics circuit from surrounding EM fields and through connecting wiring is completely common and ordinary, and anyone with even just a little experience in making measurements on AC electronic circuits will be aware of this, and will take steps to account for this if necessary in their measurements. I think you will be much better off in situations if you think you are seeing something unusual, to just provide a clear explanation of what you are doing and provide a circuit diagram if necessary, and others with some electronics knowledge and experience can help explain what is going on, or suggest steps you can take to better understand what is really going on.
