Is joule thief circuit gets overunity?

.99,

As for Q on time, no, I have never considered that an issue because of the averaging.  Bill had asked about the duty cycle and the post I think you are referring to is my response to his question.

You are now ok then with the Pout computation? My concern was that averaging was not being applied. As far as the Pout values being all over the map, I am pretty sure it is a combination of scope offset and inductive reactance between the scope probe tip and reference.

.99,

I now believe it is correct. 

I stared at it too long yesterday and in the midst of it all forgot that in the end, Pin(avg) is removed from Pout(avg) when the net power calculation is performed.

@All

Now that both the Input and Output calculations on the Spreadsheet are correct.  We should give poynt99 time to hook up his 4-CH DSO and show us the resulting waveforms.  He can start with low Input barely lighting the LED and slowly work up to 1.5V.  Approximately 5 points will do.  He can also post the raw data and I shall be happy to do the spreadsheet analysis for him.  His 4-CH scope will resolve the problem of measuring simultaneous Input and Output.  (Which cannot be resolved with two separate 2-CH DSOs.)

The price of the Atten is US$200.  The price of a 4-CH Tektronics is over US$2,500.  With the new excitement in Hong Kong and ShenZhen, that sum may not post an absolute roadblock.  In any case, the Universities will have a first crack at it.  Poynt99's posts will help to get that happen.

A piece of Good News to share.

It looks like UNI-T has a 4-CH DSO that retails for less than USD 1,000.  Mr. Zhou is a dealer for UNI-T.  He does not carry that product for the moment as there are few customers requesting it.

There is a strong possibility that we can cntact UNI-T manufacturer and get them excited about the Lead-out Energy and why that a 4-CH DSO may turn out to be a winner.

Someone can contact Tektronics and do similar presentations.  Then we shall have experts from the manufacturers doing the tests.  There will be no questions on their capability in doing the calibration, setup and analysis.  The posted OU results will be confirmed beyond any shadow of doubt.  The Floodgate for research and development for Lead-out Energy technology is now open.  When will the water "gush" gout???

The oscilloscope analysis for Board 107.


Average Output Power
12.05105778 watt
Average Input Power
0.009865636 watt

COP = 1221.52

This Board 107 will be carefully studied and preserved.

Well, I see tremendous progress has happened while I've been away.

@All,

It is now clear from the pictures on reply 562 that the Average Input Current can be tuned to 0.  Since the Input Voltage is always positive, we can get Average Input Power close to zero.  The Output Voltage and Output Current are always positive as seen in the many Output waveform graphs.

This means that we can tune the COP to almost any value.  (from large positive to large negative).  This fully explains the DSO analysis results.  It also explains why a rechargeable battery used as Source Input can show increasing voltage (being recharged) and decreasing voltage (being drained).

Everything makes sense.  The 200 Boards from Mr. Zhou are guaranteed to be OU if we tune them with the DC Power Supply!

Board 80 can definitely be demonstrated as OU in front of the Hong Kong Government.

All Glory and Honor to the Almighty.

@PhysicsProf:

You have the Atten and two boards.  You are in the best position to confirm the discussed findings.  Thank you in advance for your efforts.

@PW:

You can see that magic can be perrformed on Board 80 (or any of the Zhou boards).  You can name a COP (positive or negative) and any person with a DC Power Supply can tune it for you.  A lot more will be done on Board 80 in the coming weeks.  Thank you for asking TK to reproduce the "equal" crossing graph.  That triggered my thoughts on the Board 80 experiment.

Remember when Sean McCarthy of Steorn pointed out that he could "tune" the Orbo at Waterways by moving his pickup coil closer to his rotor? From COP 3 to COP 10 and even more?

Welcome to reality: Yet Another OU claim that only works when hooked up to, and tuned with, a power supply. Or a battery of just the right voltage ( a bit more plausible ).

Does PhysicsProf have a lot of experience doing power measurements with oscilloscopes? I'm just wondering why he's in the best position to do the appropriate testing.
