Testing the TK Tar Baby

[TinselKoala]

@PW, EA:

A simple analysis using Ohm's Law will show that significant power is dissipated in the Q1 mosfet itself during the DC portion of the operation, and experiment has shown that the Q2 mosfets also heat perceptibly during the oscillation mode. The heatsinks are required, but as I have repeatedly stated, the configuration shown in the current editions of the papers makes no sense, heat-wise. The stack of 4 on big heatsinks should be in the Q1 role, sharing the high current of the "Q1 positive gate drive" mode that makes the high load heat, and the oscillating Q2 only needs the single mosfet on the smaller heatsink. The waveform operation of the circuit will be almost exactly the same, but the mosfets will be much less stressed if "Q1" is played by the stack of 4 and "Q2' is the lone mosfet.

Regardless, the mosfets do heat significantly, depending on duty cycle and total battery voltage used, in spite of Ainslie's claims to the contrary, and anyone building her circuit will find this out for themselves.

This means that the circuit is not as efficient at heating a load as straight DC will be at the same average _input_ power levels, since significant energy is wasted heating the circuit elements other than the load resistor. However.... some intrepid experimenter could immerse the entire circuit, load, mosfets and everything, except the battery, in oil and monitor the heat of the oil, and compare the power dissipation of the total circuit to that of the load alone that way.

Or one could wave hands around and allude to "tests" for which no data are presented and make up all kinds of crazy crap, like the NERD does.

TK,

I cannot disagree with anything you said there. I don't have any time right now gotta go but I will check back in later.

The immersed enclosure is something I would have suggested a long time ago, except the total exclusion of heat dissipated in the circuit components, while measuring the heat in the load as intended proof of an anomaly, is a constant source of amusement for me.

Yes, it has been a barrel of laughs for me too.

I especially am amused by Ainslie's continued claims that the mosfets don't heat, when they are mounted on large heatsinks for some strange reason, and she has reported several failures.

Also.... no one _except me_ has yet offered ANY explanation of why ALL the NERD "high heat mode" tests from the Demo video on have only used a 48 volt (4 main battery) power supply. (This is evident from the Ainslie scopeshots I've managed to collect and post.)

Come on.... I'd really really like to hear some explanation (other than mine) of why, even in the demo video, one battery was removed from the original stack of 5 used in the first half of that video.

And now we're out of reach.  LOL.

Like hell you are out of reach.

Are you gonna stop people from personally contacting those newly seduced recruits of yours on your forum and presenting them with your 10 year history of delusion-induced lies?

I dont think so.

They're all available here: www.journal-of-nuclear-physics.com/?p=645 where there is no censorship of truthful comments.

See you around where you least expect me Sweetheart ..I aint goin' away.

@picowatt:
It might not be possible to add the internal protection diodes to the F43's output stage as simply as you have suggested, because of this very handy feature of the F43 function generator:
