Is joule thief circuit gets overunity?

[Poit]

I hereby acknowledge the contribution of TK, PW, Poynt99 and others to bring out the scientific truth in this thread.

The simple JT is unlikely to show OU.  But their efforts have help to identify a procedure and the use of a high end DSO to get correct Input and Output Power measurement.  This will benefit all researchers.

I shall let Mr. Zhou and the Atten Technical Support to work on the issues related to the Atten and they can read this thread.  l shall take Poynt99's advice and use another Brand of DSO being sold by Mr. Zhou.  (I may even get the 4-CH tektronics in a few weeks and the properly trained people in Hong Kong to help.)

I should have started these postings three years ago when I first got the Atten.  I never mastered all its functions (just like I never mastered those on my mobile phone).  The students read the instruction manual and helped to set it up.  Poynt99 may still remember that I used Voltage Vrms and Current Vrms to get the Tseung Comparison index for my different badly soldered prototypes.....

Deliberately exposing one's limitations for all to see and learn has its benefits.

I have nothing useful to contribute, I just want to quote (above) incase he decides to recant. "The simple JT is unlikely to show OU."

That's great, thank you, I feel so much better now.

But who is picking up the tab for all that Divine Wine?

@TK

Do not worry about "who" picks up the tab.  Poynt99's 4-CH Tektronics costs LESS than one bottle of his fine wine.  His family fortune is within Forb's wealthiest 100.  More money does not mean much to him or his family.  ***Many tourists from China now buy luxury items.  Some handbags or watches cost more than the Tektronics.  Which one is more useful?  Which one is likely to create more "meaningful economic activities"?

*** Had a pleasant dinner with Ms. Forever Yuen and her boyfriend.  Forever is the one who introduced the students to help me a few years back.  They will help as needed.

I am sure of one think about the joule thief, that there is no OU, in fact it is rather than a economizer of energy, the more you are in the resonance frequency, the lesser energy is consumed, And as it is impossible to arrive at the exact resonance it is impossible to have 0 watt consumed.
I hope I'm not mistaken.

If you want proof , just run JT from a charged capacitor of less then 1 farad for a week duration. Possible ? No ? So, you have nothing.....
