An energy harvesting project

[JulesP]

I agree that a CoP of 53 is very large and I now think that some of that is due to the Battery Management System installed in Lithium batteries that is interfering with the measurement process. However, even if it is that high that doesn't mean high power levels as that depends on the energy applied to the generator and also the time involved in the charging process. In this case, it would be more like 200W.

As I have repeatedly said, the power tests have yet to be done to confirm useful power and you are right in that full proof of useable energy is not yet there from my work. CoP results are only a part of the story and the manual I am writing will just allow someone to replicate them. Once the power tests are done in early 2023 then I will update the manual. I have only written the manual at this stage due to various requests to be able to replicate my findings and, in some cases, to improve on peoples' builds that already exist.

I am posting another report here from using capacitors instead of a battery that shows that the battery chemistry is fundamental to the energy gain process. Now, this can mean either of two things - one that the electrochemistry is itself the 'fuel' for this process and so over time the battery will decline in its normal function or, secondly that the chemistry is a necessary and important intermediary in an energetic process and pathway yet to be determined.

Further tests will need to be devised to sort that lot out.

So to date, even though you claim a COP >> 1, your batteries do run down over time? You believe that your automated switching circuit will fix this?

I would like to see this simple test conducted.

To demonstrate COP > 1, do this.
Start with two batteries, identical.
B1 is fully charged (100%SoC). B2 is partially charged (80% SoC).
Place B1 as Run battery. Place B2 as Receiving battery.
Run system until B2 is fully charged, to 100% SoC.
Switch (manually) B1 and B2.
Run until B1 is fully charged, to 100% SoC.
Switch B2 and B1.
Run until B2 is fully charged, to 100% SoC.
Switch B1 and B2.
Run until B1 is fully charged, to 100% SoC.
Repeat as long as you can.

If the needed run times decrease with each cycle, you have something interesting.
If you are soon, after a few exchanges of B1 and B2, unable to reach 100% SoC on the Receiving battery, COP < 1.

I concur.

I concur.

Yeah doing this with a battery is an energy waster, try it! but doing it with capacitors is a different game!
look on the JB site I did a pcb for that device, I will try and find it and post it.
