Testing the TK Tar Baby

[TinselKoala]

I swear, this is better than "24".

What will Little Miss Mosfet come up with next? What equipment will she damage, how will she next illustrate her ignorance, what incompetencies will she next exhibit?

What drunken doggerel will she misspell next?


But even more importantly.....

WHEN WILL SHE DELIVER ON ANY OF HER PROMISES???

Where is that video that we were promised last week, showing her REFUTATION of picowatt's claim... and  mine, and everyone else's who has bothered to look.... that the scope traces in question indicate a blown, miswired, missing mosfet, or even A DIFFERENT SCHEMATIC?

WHERE is that video refutation? Or.... is it perhaps.... that we will NEVER be seeing that refutation.... because she simply cannot do it?


Her FAILURE to produce the refutation that she was so confident about, and has delayed for so long... months now.... and that was promised to us last Monday, then by the Weekend, then by dinner time Saturday.... has now disappeared completely.

This demonstration of course must be done with the EXACT CIRCUIT given as used before ... either one..... so the excuse of waiting for a capacitor or special shunt is invalid and not applicable. But I have already said that I would even accept a refutation performed with 36 volts in the battery pack, all other things being the same as before.

THEREFORE..... she clearly has acknowledged, by this grave omission.... that she was wrong, that the mosfet was indeed blown or miswired, since she can't reproduce the trace with a correct and functioning mosfet.

THEREFORE THE MANUSCRIPTS MUST BE WITHDRAWN IMMEDIATELY--- or a very egregious scientific FRAUD..... or rather pseudoscientific FRAUD is being perpetrated on the research community. But then we knew that already.

Is it not possible to use smaller sealed lead acid batteries batteries for these tests?

Personally I would not allow any vented or liquid electrolyte lead acid battery anywhere near my test equipment without being in a proper enclosure with venting to the outside. Not for any length of time at least.  A proper battery box would be able to contain acid, used clamped terminal connections, be fused and actively vented.

I cannot imagine why smaller 4.5-8 amp hour sealed gel-cell batteries could not be used.  They would be much safer, can be placed very compactly right next to the circuit and would require less wire length to connect and interconnect.

The smaller amp hour rating would also reduce test duration times.

Hi PW,

There sure is smaller lead "liquid" acid batteries ......

Exide, GT-H, Group U1, 12 aH (RC 25Amps @ 25 minutes), 7.8 x 5.2 x 7.3 inches ; 16 pounds

This is the battery type others and myself have used (lawn tractor) instead of a "gel" type and are quite nice having lead lug positive and negative posts with a hole for "bolting" electrical connections.

Just so she knows, the reason electrolytic capacitors are being discouraged is that they can often have a lot of internal inductance.

Capacitors, essentially being two flat conductors laying side by side with a dielectric in between and stacked or coiled up, can have a large amount of internal inductance by nature of their physical construction.  At high frequencies this internal inductance can add reactance to the capacitor causing it to no longer act like a true capacitor.

If the capacitor she selected is in a very large package, i.e., larger than 20mm by 45mm, it is likely to be a large electrolytic that can have a lot of internal inductance and a high ESR.  The reason .99 specified the film cap that he did is because the data sheet states that it has a low inductance (athough no values are given).

The newer low ESR (equivalent series resistance) electrolytic capacitors typically used for switching supplies and rail decoupling in computers are fairly low in inductance.

A 10uF 35 volt capacitor of this type would only be 10mm by 15mm or so in size.  To eliminate the effects of any small inuctance that is inherent within the 10uF cap, a smaller value, very low inductance type capacitor such as a .1uF ceramic is parallel connected across the 10uF cap.  This allows a capacitor with only a "low" inductance to act as a "very low" inductance capacitor.

I would only use a sealed type battery that does not vent and can can be tipped over around any of my equipment.  Battery acid fumes are highly corrosive.  If liquid electrolyte batteries need to be used, a sealed battery enclosure, actively vented to the outdoors, should be used and include inline fusing.

Even if all the fumes did was cause some switches to get noisey on my equip down the road, it would not be worth it.  Add to that the possibility of getting something across the batteries and again, a recipe for disaster.

How many here feel she would be qualified to bring a few tubs of sulfuric acid, some lead, and all that stored energy into their house?  Look at those battery clamp images again and think about that.

I don't see whay small gel-cells aren't considered.

ADDED:  Gel-cells can be had with bolt on lugs as well...  The entire battery stack made from small gel-cells would also be very compact allowing the use of short interconnects and lead wiring, hence lower wiring inductance.

Hi PW,

I can agree with your comments on the "liquid" acid and if not being careful can have huge problems .... like a gallon of household bleach or ammonia if dumped inside a home.

The problem is, most of the "alternative energy" devices we see use car batteries with "liquid" acid, having a proper scientific replication of any device all materials used should be as close as possible to the original device having said claim(s) ..... technically speaking. The other part chemically speaking is the electron transfer from plate to plate inside the battery that some say operate differently between "gell" and "liquid" as Rosemary has argued before one being more free to do the transferring. This of course is up to speculation but the "scientific replication" part kicks in here is my only concern.

I haven't had any problems and with the COP>17 circuit even with one of my custom made 10 ohm borosilicate glass resistor inductors with a 2 3/4" OD that had some healthy pulses going to the battery bank. The only real concern to me was doing the "recharge" mode the batteries got warm like any other battery being charged by a 120VAC wall outlet 12VDC charger @ 6 amps also having the proper air ventilation during the process and some baking soda handy.
