Is joule thief circuit gets overunity?

[Pirate88179]

I am hoping to work on it Monday, as I am off that day.

I want to make a prediction here.  I believe that .99's tests will show somewhere between .60 and .69% efficiency.  Not bad for a simple JT circuit but no where near 100%, much less 200%+ as has been discussed.

From what I see in the photos, these boards are not even using ferrite toroids, they appear to be using the powdered iron type.  Obviously, these will work but we have found that you need a very high permeability ferrite to get the numbers into the 80% plus range.  Since the testers are not using these toroids, my prediction is derived from numbers we have seen in the earlier days of the JT topic.

For example, off the top of my head, in the Jeanna's JT circuit, we used ferrite with a permeability rating of 10,000.  That turned out to be a great circuit that could do many things but, it was not O.U. by any means.

The above is just a prediction and/or educated (somewhat) guess.  I just wanted to get this on the record.  This is not intended in any way to detract from Lawrence's efforts here at all.  He has gone through a lot of trouble and has spent a lot of time on this and, I admire him for doing so.

When the numbers come in from those that really know how to measure such devices, I may be proven wrong, but I do not think so.

I look forward to .99's results.  If Lawrence is correct, I would be very happy for him and be one of the first to congratulate him.

Is TK testing one of these boards?

@Bill

TK is NOT testing one of these boards.  If he had one or more of these boards, he would have used the high end oscilloscopes to check the results.   At present, he is trying to help by scrutinizing for possible experimental errors.  I appreciate that as it prepares me for the inevitable meetings with the Top Universities.

That brings up the point – why are the well known JT researchers not using the oscilloscopes to check their circuits?  My present circuit is just the plain JT.  Admittedly, I rejected many – probably more than half.  Now I rely on Mr. Zhou and team who are much more skilled.  Previously, I relied on G-LED and BSI Hong Kong.  They are commercial entities and their primary goal is to make money.  They used oscilloscopes and got OU results.

Without the oscilloscopes, the research is like shooting birds in the dark.  My contributions are to propose the Lead-out Energy Theory and use two relatively cheap oscilloscopes.   But the floodgate is now open.  Any individual or organization with USD2,000 to spare can jump on the bandwagon and benefit the World.

*** Bill, you are so confident in predicting the COP is from 0.6 to 0.69.  What is the method you normally use to measure the COP of your JTs?

 At the funeral service of my Secondary School Science Teacher, Mr. Tam

I had a chance to meet many old schoolmates.  Most of them either lost most of their hair or their hair turned white.  The organizer of the planned 50^th meeting of the Old Boys that graduated in 1963 was there.  He said that at least 30 pasted away.  Another 10 might be too sick to come.  Some lost contact altogether.

One of them said: "If you have something you still want to accomplish, do it now.  At our age, there is not much time left. "

I got an Easter gift that carried a similar message.  So I am preparing the mass email to sow the seed.  The Boards for USA will be hand-delivered to Prof. Julian Tree in Shenzhen on April 5, 2013.  Another 100 oscilloscope test-ready Boards are being produced.

May the Almighty guide us on the right path to benefit the World.

Waveforms of Board 77,78 and 79.

The last three Boards in my Bedroom are 77, 78 and 79.  Another 100 has been ordered.  Many of the Boards have gone to Churches, Schools, Friends, Charitable Organizations.  When I sow seeds, some will fall on rock, some will be eaten by the birds etc.  The good thing is that I got donations to help me buy more seeds.

Hong Kong and China will become the leader in Lead-out Energy Research not because of me.  The generous and risk taking donors deserve much credit too.

Board 78 is different from the rest.  I shall look at it in more detail.

Board 78 waveforms and oscilloscope analysis.

Average Input Power   = -0.05546 watt
Average Output Power = -0.01164 watt
COP =0.21   (two negatives make one positive)

Since both Average Input Power and Average Output Power are negative, this board is giving energy out to both the DC Power Supply and the Load.  Energy must come from the surrounding environment.  This Board 78 will be kept for further research.

God reveal the secrets to those who try, try and try.....
