Is joule thief circuit gets overunity?

Lawrence,

You seem to have forgotten this post:

where I clearly show that a high-end scope IS NOT REQUIRED to demonstrate that the input current trace does not ever cross the 0-reference axis.

This of course would confirm that recharge current never goes back to the battery or capacitor as you have suggested.

Buying a new analog oscilloscope in Hong Kong is not that easy.  It is like buying a DOS based PC.  Retailers just do not carry them anymore.

Another piece of good news from this work is:

(1)    A wealthy individual (not interested in financial returns) is willing to donate the necessary funds to get a high end DSO.
(2)    A group of "poor" inventors are willing to work together on this Lead-out Energy field.  Some of them are working on Joule Ringer and other circuits.  They are happy to have the use of high end DSOs and share the experience and expertise.
(3)    A Lawmaker is willing to discuss the possibility of Public Fund Support for "research centers" open to the General Public.  He feels that it constitutes "meaningful economic activities".  Hong Kong should not depend on finance (stock and property speculation?)  totally for its long term future.

Thanks for showing the results on your high end 4-CH Tektronics.   It helped all researchers.

God works in mysterious ways.

The cheap (no oscilloscope) video seems to indicate charging and draining of battery with capacitor in the circuit.

What does that mean?

Lawrence,

I did not say you had to use a NEW analog scope. There is a China version of ebay; so surely you could buy a used one there for $100 or less.

Also, you do not have to use an analog oscilloscope to verify your findings. Borrow anyone's scope, as long as it is NOT an ATTEN brand, nor one made by the same manufacturer.

What about Mr. Zhou? Does he not have several different brands of scope for sale? Could you ask him to verify the current trace with a different model?

What does that mean?

It means that your DMM is trying to "lock on" to a signal that is actually a pulse train instead of a steady signal. The meter has a time constant over which it averages its instant input values for display. It does not mean that your system is "charging and draining" its battery, it means that you are looking at a flag flapping in the wind, by blinking your eyes rapidly. Sometimes you see the flag on one side of the pole, sometimes the other, but the flag remains attached even when your eyes are completely closed.
