Testing the TK Tar Baby

[MileHigh]

TK:

I believe a RAT conclusion is that here is a net reverse current flow back into the battery.  Certainly they allege that there is a net power flow back into the battery.  That is also synonymous with "COP infinity."  So that's why it's interesting.

Keep those delicious lip-smacking oscillations coming!

With the current measurements and the led's and light bulbs, are we trying to see if current is going back to the battery?

If so, it got me thinking. If we had 2 very large caps, one in series with a diode in forward direction, and the other with a series diode in the opposite direction. The see which cap fills first. Or at least which is taking charge faster.

Then a simple thought came to mind. Not related.

If we have a 12v battery with + connected to the cap, the other end of the cap connected to a light bulb, and then the bulb to the - of the batt.

The light will light and gradually get dim then no light as the cap is charged. Then when the cap is fully charged, we can use that "once used" energy again to light the bulb for another cycle without the battery.

Some of the energy used , then reused, is a bit useless in light output, but the energy was still being used and reused to make light and heat.

Could it heat water for near half the input?


So if we have a converter or a JT( may need to be expanded upon) we might just might be able to have a 2 for 1 sale for powering other items ;]

Ok, here is a very simple example.

The switch at the top right is held on til the cap fully charges through the load and then open the switch.

Now we close the switch in the middle of the circuit to discharge the cap into the load, without the battery. When the cap is fully discharged, the cycle repeats.

The scope shots show the source on the left and the load on the right.

We can recycle energy. Use it more than once.   

Did we gain anything?

IRFPG50s are in hand, 5 each.

I also have some pegboard and some white paint. Those clipleads with the black tabs on the alligator clips though... those have been hard to find.  I might have to use bare clips. That will obviously invalidate my reeeee search.

But just in case it doesn't....

@Mags: When you have current flowing through the resistor, power is dissipated as heat. When you have current flowing into the capacitor, power is dissipated as heat. When you have current flowing out of a battery, power is dissipated as heat.
But you already  knew I would say that.

@MileHigh....yesss..... As I recall RA made some pretty strong statements about the state of LEDs in her circuit. SO at minimum, I think my results contradict her statements... but probably not the actual performance of her circuit. Can you really imagine them actually testing as I did? No, I cannot. She's just making stuff up out of her head.
If she's not.... a dollar's worth of parts and ten minutes with a borrowed video camera could prove it.

@PW: sorry, I didn't mean to ignore your question about scoping the batt. Yes, I did do this, and at first inspection it looks like her batt trace, but of course at lesser amplitude.

But I have the PG50s in hand, and later on after I've come down from the drive home, I'll stick them in and repeat some of the baseline testing I've already done with the 830s.

I also scored some real, NOS, non-Chinese made, #1157 light bulbs, two filaments each.

@Mags: Can you have your sim integrate those two sets of traces? Integrate over the time the negative waveform on the left, and compare that to the  total integration of the two positive waveforms on the right.

Ah... the wonders of modern computing. If I want to integrate a waveform on the HP180, I have to trace it on paper, cut out the tracing, and weigh it on an analytical balance.
