Is joule thief circuit gets overunity?

Boards ready for shipment

I shall wait for one or two more days before mailing.  Any last minute suggestions on additional tests???

@Conrad,
Here are the results you asked:  COP = -2.93 on Board 33 for overunityresearch.com using a New AA battery.

@Itseung888: Thank you very much for doing the measurements with a 50µS time base.

I also looked at your data file DSO_analysisc.xls. The measurements look o.k. but I am not a real expert. I would check the resistors (shunts) over which you measured, but you have done that I guess.

It also astonishes me that you measure a COP of almost 3. That should destroy your capacitor on the "demo board with capacitor", because the Voltage would rise and rise. I do not understand how your measurements can show this result, but there are very many things which I do not understand, so I do not want to give a verdict.

It is very important that you send your boards 38, 39 and 33 to the forums. This will give people a chance to do their own independent measurements. This is always a good idea. You will only be believed once other people can repeat your measurements. (And I admit that I would also like to see third party verification.) I am looking forward to the results.

I have done many measurements on my Joule Thieves and some of them look like your Joule Thieves (as far as the schematics are concerned, but I might have different components, e.g. the Toroids). I did not see OU, but that does not mean much. So, hopefully the "third party measurements" by the people to whom you send your boards will clarify everything.

Greetings, Conrad

Hello all,

before someone claims overunity in hf-circuits one should understand the technical note here and perform the necessary measurements before:

10 other Boards will be prepared for confirmation as the next task.

One of them will be for Patrick Kelly.  Others will go to India, England, Australia, USA and China.

The professional who soldered these boards and did the initial tests for me (Mr. Zhou in Shenzhen) is feeling confident that he and his team may be able to produce hundreds or thousands of these boards with confirmed Average Output Power > Average Input Power characteristics.  He and Mr. TS Lau will team together to supply these boards to the World.  The plan is to allow people to order on-line via eBay or similar.  The details will be posted when ready.

This may be the first "guaranteed OU device" available for purchase....  Replicators and improvers are expected and welcome.

Once the flood gate is open, there will be products pouring out.

Lawrence, your circuit is not overunity.

Your _measurements_ might indicate to you that it is overunity. So what? I am eight feet tall -- when measured in a certain way. However, I still need to stand on a stool to reach the top shelf, for some reason. How can that be?

Your circuit, when measured in your chosen manner, is giving you readings on your oscilloscopes and spreadsheets that you are interpreting as OU. Is there ANY OTHER WAY, besides your measurements, to see OU performance? There is not. You cannot run one JT from the output of another, daisy chaining them and collecting excess at every step. Your capacitors do not fail from buildup of excess voltage. Your lights don't even run as long with the JT as they do with only the capacitor. You can't wind up with a battery that is more charged than when you started. In short, your measurements fail what is known as "concurrent validity"-- other objective measures of OU performance fail to see OU in your JT circuit.
