Selfrunning cold electricity circuit from Dr.Stiffler

[PaulLowrance]

Hi Dr. Stiffler, Stefan, and poynt99, & all,

Today the Maxwell boostcap BCAP0650 arrived, so I did a few quick tests. I'm a bit puzzled over the results, and would like your input. More tests are required to say for certain, but here's the data from two measurements,

Measurement #1:
Description: How long it takes to charge the BCAP0650.
Capacitor initial voltage: 210mV
Capacitor final voltage: 220mV
Current source: 199 mA
Time duration: 26.9 sec
=======
Calculated capacitance = 535 F

Measurement #2:
Description: How long it takes to charge the BCAP0650.
Capacitor initial voltage: 410mV
Capacitor final voltage: 420mV
Current source: 42.1 mA
Time duration: 150 sec
=======
Calculated capacitance = 632 F


Although inconclusive, could this suggest that bcap requires *less* energy to charge when *higher* current is used?

If confirmed, then it appears the bcap behaves as if it has less capacitance when high current is used. When the bcap was charged at 199mA, the capacitance was 535F. So if we place a load across the bcap and drain it at 42.1mA, would it have 632F? If true, then that indicates excess energy.

Tomorrow I'll do the other experiments to know for certain. It's probably nothing, and easily explained, but I thought this was interesting nonetheless. Tomorrow we'll know for certain.

Any input is greatly appreciated!

Regards,
Paul

Hi Paul,
what voltage and charge resistor did you use to do this ?

Yes, Supercaps seem to be very dynamically interally.

Just have a look at what Dr. Stiffler has measured in his thread and
found out about his 3 Farad caps.

It seems possible, that the capacity varies with the value of the used charge/discharge current.

Maybe we can use this somehow to design a circuit to capture excess energy from the background ?

Paul:

That was good work there.  This was what I have been saying for almost 2 years about these type of caps, they do not behave in a "normal" capacitor manner.  At least not in my experience anyway.  Thanks for posting your results.  You will enjoy that B-cap, I promise you.

Hi Stefan,

A current source unit was connected to the bcap along with a current meter in-series, of course, and a voltage meter across the bcap. That's all.

It would be amazing if these caps capture excess energy. The only theory that comes to mind is based on quantum tunneling where a percentage of the more energetic charges tunnel across the polar molecules. I don't know, that theory is a stretch, and I'm not Stephen Hawking or a QM guru.

Bill,
Thanks. Stefan's correct that Dr. Stiffler has mentioned this odd effect. If true then you guys made the discovery of all discoveries.

Regards,
Paul

Paul, I hope you know that a capacitor, and especially the ultra capacitors (and batteries as well) have a significant internal equivalent series resistance.  When you measured the voltage during the test did you first stop the current and then take the voltage reading?  That's what you have to do, to at least not have this internal resistance drop the voltage as the current is flowing and thereby confuse your voltage readings.  Things are more complex then this simple model, but it suffices for this explanation.
