Is joule thief circuit gets overunity?

So that's pretty much that, then. OK, fine.

Here is my version of the Ghost light.

The Ghost Light LED can be on forever?  At least 7 days and lights without dimming.

For tuning purposes, one can focus on Minute3.jpg.

The Output Voltage Waveform has more peaks.  That potentially produces more power peaks.  The percentage drop in amplitude is less than that of the Input.  This is a good candidate for COP > 1.

Another angle is to look at the frequency.  Can we use a low value of DC power supply to keep the circuit at that frequency?  Can we build a circuit to maintain that frequency???  It is like keeping the same frequency for a radio station.  Get there and hold it there.

Once the top Universities see the possibilities and the results from their top-of-the-line oscilloscopes, They will take Lead-out Energy technology to the next level.  The Top Chinese Universities are looking for projects that will let them excel.  They are good candidates to become Wine Servers.

God Bless.

First, and perhaps most importantly, Power is NOT energy. Power is not necessarily "conserved" because you can take lots of small chunks of power and concentrate them into a bigger chunk. ENERGY is conserved.

Second..... if you load samples from your DSO into your spreadsheet and have the spreadsheet integrate the values making up the instantaneous power curve, you need to make sure you aren't "looking at your data thru a picket fence".  That is, all DSOs are _sampling_ instruments, they do not read continuous values from your signal. They sample it at discrete intervals. Digital Sampling Oscilloscope.  Many DSOs... high end ones....have very large sample rates like 1 Gs/sec. Clearly..... if you are sampling a waveform at 1 Gs/sec..... you are going to have a +lot+ of samples per cycle. A lot of data for a spreadsheet CSV file. On the other hand if your scope is a basic one, it probably has a much slower actual sample rate, and may even be interpolating between sample intervals rather than giving you actual measurements.
This means that using a spreadsheet to integrate a complex signal with fast risetimes, based on data dumps from a low-end digital scope is a process that is.... er.... um...... "fraught" as someone once said. Fraught with difficulty and opportunities for error, that is.
It is better, in general, to use an integrating power meter like the Clarke-Hess power analyzers, or in especially problematic cases, even bolometric power analyzers, or to beg or borrow a high-end scope with huge sample rates and built in integration math, and have the scope perform the necessary integrations on-board.

That is very insightful of you. I know a little bit about digital sampling and how music software works and you are absolutely right. Your explanation of the artifacts of digital sampling concerning the reality of measuring power-in/power-out is very helpful.
Now I understand the so many years of discussion around this issue. One would have to have an infinite amount of sampling to allow instantaneous measurement of voltagexcurrent In and Out to measure correctly.

I admire your patient and politeness with our friend Itseung in his wonderful work when explaining the issues of the data.

How that device you mentioned (Clarke-Hess) works internaly if you don't mind asking. If they are not sampling, how are they calculating the true power?

Many thanks,
