Is joule thief circuit gets overunity?

The equation "watts = amps x volts" is only valid for resistors in DC circuits. See http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elepow.html

When measuring DC, the amps and volts measurements can be "average", "rms" (they are the same for DC) or an "averaged-instantaneous" measurement. The result will be the same.

This is the calculation the scopes are making.

No, you are mistaken. The scope is making an "averaged-instantaneous" measurement only. The scope is taking many simultaneous instantaneous measurements of current and voltage. Then the scope is set up to multiply each simultaneous current and voltage measurement to produce an instantaneous power p(t). When an averaging function is applied to p(t) (either internal to the scope, or via spreadsheet computation), the average power is the result.

Now, please study what I have posted until you actually understand it, or do your own research if you do not believe me (Attached is a good place to start). Until then, please refrain from posting misleading information as to how to make power measurements with an oscilloscope.

This is true, but it does not solve the problem. The problem is that the equation being used to compute power is not valid for an LED. It is only valid for resistors (and resistances that can be modeled as a resistor).

@ ltseung888
I have spent over a day trying to help you understand what is wrong with the measurements. It seems I have not succeeded. Perhaps it will eventually sink in. Now I have other things to do. Have fun with your "OU" circuit. Eventually you will realize that it is not OU. Then perhaps you will find my comments helpful.

Another tester in USA?

I would be glad to cooperate with this effort to show the world how well ZPE works.
I am in the U.S.

Please give me your mailing address.

If you are willing to post your test results on the Internet - in overunity.com for example, I shall be happy to send you a prototype board FREE for testing and confirmation.

Let us try to benefit the World together.

Thank you for your explanations to xee2.  I shall focus on training the many interested groups in Hong Kong and China.  Hong Kong can lead the World in Lead-out Energy research.  Since I am also an US Citizen, an oscilloscope test ready board will be sent to President Obama via proper channels - US Consulate in Hong Kong, United Nations in New York??? 

Thank you also for providing the bench for me to dump my preliminary work and thoughts (some are now known to be mistaken) at OUR for these years.
