Testing the TK Tar Baby

[TinselKoala]

Yes... but there probably aren't going to be any upcoming tests. Did you not see her notice that she's sending the apparatus.... the one we haven't seen a photo of in over a year and that FTC doesn't think even exists any more......  she's sending that off to a "well funded laboratory" in the USA next week and isn't expected to have it back before mid-July.

(Of course, if I had a free energy device, I could test it a dozen times in the next week before sending it off, but then I don't have a gardener or maid.)

And of course... many's the slip, between the cup and the lip. How many times have you heard of an overunity device that's sent off for testing, and is either never seen again (suppression, you know) or doesn't work on arrival, or even on return home?  When you've been watching as long as I have you will have seen this happen many times. That's why it's so rare for anyone to send their devices off !! Heck, you can't even trust UPS or FedEx to deliver stuff without breaking it any more.

Seriously...  I really don't think we are going to be seeing any tests at all from the NERDs. 

But the one I'd really like to see is one that heats the load to high heat, using a 72 volt battery pack, and sustains it for 24 hours, using the circuit configuration and mechanical build that we have been shown.
Or one that heats to high heat using just the oscillations alone.
Or one that sustains a power level of a kiloWatt for 1.6 hours, yet shows a scope trace like Fig. 7. Oh... right, the 5.9 megaJoule claim has been withdrawn, sorry. How about just boiling some water -- I mean actually boiling it, not some tiny bubbles coming up from the resistor --  in a one-liter container, with a scope trace like Fig. 7.

Mid July is just around the corner...

I did not see that time line.

Yes, it does seem a bit squeezed doesn't it. Packing up, including presumably the batteries (that we are now informed are factory rejects, hence impossible to match),  shipping off to the antipodes, the setup and testing and evaluation by the "well funded laboratory"... sending it back.... all that, in just a few short weeks. Remarkable. I can't even get a flatpack of transistors from Singapore in that time.

See the image below.

Oh.. .and the part omitted from her quotation from Brian Ahern... omitted for some reason, but not commented on or corrected... is this:

That would provide 1.99 megajoules. That is nearly double the capacity of 5 batteries with 60 amp-hour rating.

I am sorry to be so stuck on this but it remains astounding.

Look, Brian. The Watt is a rate, of a Joule per second. Its _units_ are, at the top level, JOULES/SECONDS. The Joule is a Watt-second, that is, the amount of energy that a Rate of One Watt, sustained for one second, dissipates. Its units are, at the top level, WATTS x SECONDS.

Now, if you have 5 batteries that are 60 amp-hours, and you simply multiply as you did, 5 x 60 x 60 x 60 = 1080000... is your answer in Joules?

Let's put the units in and see. 5 batteries x 60 amp-hours = 300 amp-hours.   
300 amp-hours x 60 minutes/hour = 1800 amp-minutes.
18000 amp-minutes x 60 seconds/minute = 1080000 amp-seconds.

AMP-SECONDS, not WATT-SECONDS.
In other words, your 1080000 number is not a number of JOULES at all. To arrive at the number of JOULES... the ENERGY CONTENT.... you need to multiply again, by the voltage, because Watts = Amps x Volts and you need Watt-seconds, not Amp-seconds, in your answer.

Rosemary,

There is another, and in my opinion, better way to approach the battery draw-down testing.

Forgo the comparison between the experimental apparatus and control, and opt for a set of much lower capacity batteries such as 2 or 4 Ah ratings. Set the apparatus up for optimal performance and run it on the load for 72 hours. Monitor the temperature to be sure the load is heating to some significant degree (such as 50 or more degrees Celsius). The run does not have to be continuous, providing no charging of the batteries is done in between runs.

No 24 hour supervision is required, and the test run will be completed in 9 days or less (if run consecutive 8 hour days). 12 hour runs would allow the test to be completed in 5 consecutive days or less. [Occasional tweaking of the circuit may be required to maintain a constant temperature.]

If the batteries are still at the voltage they were at the start of the test, and the circuit is still producing the same significant heat after 72 hours of operation, then the claim most likely has validity.

Let's assume an operating load power of roughly 20W throughout the test run. Compute how long 4x 4 Ah batteries should last:

- Assume 4 fully charged 4 Ah batteries have a series voltage of 50V (4 x 12.5V).
- Assume a constant 20W delivery of power to the load.
- The constant current used over the test run is then 0.4A.
- Therefore, the batteries would normally be used up and considered "dead" in 10 hours.

I like this idea. What do you think Rosemary?
