Rosemary Ainslie Circuit Demonstration, June 1 2013

[TinselKoala]

Could it be, (horror of horrors!) that she is
actually studying and learning?  Rosie is an
exceptionally bright woman who is no doubt
fully capable of mastering many technicalities.

(snip)

Anyone with knowledge who reviews her recent posts in her "Protocols" thread, discussing the topic with .99, will see that what you suggest could NOT in fact be true. Sometimes it seems as though progress has been made, but then we see that she is only parroting big words, without real understanding of the concepts involved. She still does not understand basic functions of her oscilloscope (trace offset setting, AC vs DC coupling, etc) and she still does not understand the operation and functioning of her own FG (the claims about current flow, the effect of the offset knob, etc.). When it comes to understanding basic operation of the main component of her system, the IRFPG50 mosfet, she remains as ignorant as a baby. Go ahead, ask her what Rdss means and how much power is expected to be dissipated in the mosfet when it's carrying 5 amperes of current. Ask her to describe the linear operation region of a mosfet's functioning. Ask her if there is really no such animal as inductive reactance. Test your idea about whether Ainslie is remaining willfully ignorant, as I claim, or whether she is learning her topic, coming up to speed on technical issues and equipment operation. Ask her some technical questions!

TK,

I can't speak to the "studying" part, but the "learning" part is obviously lacking...

By the way, her "special" non-inductive resistors are Vishay RCH 25 series 1R resistors (4 in parallel).

As per the data sheet, they are specified as having an inductance less than or equal to 100nH.  Not all that special, not all that "non-inductive"...

For comparison, a Caddock TO-3P package non-inductive resistor is specified as having 4nH when measured at the leads .1" from the package (which is lowest inductance off the shelf part I could find).

As well, the inductance of all those lengths of interconnect wires used to parallel the resistors also needs to be calculated into the total inductance of the 4 resistors in parallel.  In other words, contrary to her claims otherwise, her new and improved "non-inductive" CSR is not all that non-inductive.

Of course, that is assuming that such an animal as inductance actually exists...

@Mark Dansie:
You should be aware of a few things that you might not yet have noticed.

Ainslie has been banned from many forums. Naked Scientists, Energetic Forum, this forum at least twice, and others. Why? We know why, and you will probably be finding out before too much longer. She has four separate YouTube accounts: dooziedont, aetherevarising, and two under her own name. Why? I know why. She has removed and attempted to suppress the video she posted of her demonstration from March of 2011. Why? I know why. (But the internet never forgets, so this very informative video is still viewable, with all the lies and smoking guns it contains.)

Ainslie cannot provide any evidence, not so much as a scrap of paper or an email, for her claimed vetting by the alphabet agencies and companies that she lists. The "contactable" people whose names she drops..... aren't.

The true history of Ainslie's submissions to journals is best told by FuzzyTomCat..... because the fantasy story that Ainslie tells isn't how it actually went down.

Some people on this thread, like .99 and me, have actually spent _more time_, money and effort working with and understanding this circuit than Ainslie has herself. Others have spent less time but have contributed greatly by analyzing and explaining and suggesting experiments for the builders and simmers to perform. And on other, more credulous forums, other builders have done even more work.... and have always found that Ainslie's claims are false.  Ainslie herself has been rather less than cooperative throughout this process. What I am telling you here is that Ainslie herself has done nothing like the amount of work that other people have performed on her circuit; she clearly doesn't understand it and _nobody_ anywhere is prepared actually to demonstrate, with their own constructions, that any of her claims are true. The evidence against her and her claims is literally overwhelming.

When Ainslie makes a statement -- ANY statement at all, you should require her to provide support for her contention, by outside references that can be checked. (Some of her bloopers are famous, like "Per never means division" and "no such animal as inductive reactance" and "A Joule is a Watt, the terms are interchangeable".) If she provides you with a number from a calculation.... be sure to check the math yourself. If she refers to the work of others in any way.... make her give a link that supports her reference. If she speaks of me as Bryan Little or makes any kind of "pickle" slur or other snide insulting remarks, or if she pleads that she is "just a little old lady" and complains of sexism, ageism or other kinds of discrimination..... you know that she is trying to deflect attention from the main issue: her bogus claims and her failure to support them with actual evidence. Most particularly, if she claims that some agency has examined her apparatus and data, make her prove it to you by showing you their report. If she mentions a professor's name, or any other names, by all means try to contact that person and ask them about Ainslie. Professor Gaunt, Professor Khan, and others have responded to inquiries and their responses are very revealing. You won't be seeing those responses from Ainslie, though.

So.... it will be a lot of fun to watch what she does to your forum when you start hosting her claims and your people start discussing .... and even building.... her circuit.

(I thank FuzzyTomCat for providing me with the documents attached below.)

Thanks for identifying the resistors, I couldn't make them out from my blowups of her posted photos.
But I did point out the same thing that you are pointing out: Installed as they are, any low-inductance advantage is cancelled by the long wiring lengths and the probe connections themselves.
Ainslie's apparatus has evidently not changed in any important way -- except of course the significant addition of the larger heatsink on Q1. If the photos on PESN represent her current work, we still see massive inductances in battery wiring and on the board itself. We still see the load element suspended in air with the thermocouple attached directly to it. And we still see the "smoking gun" : the use of only three batteries in "high heat" mode, along with the larger heatsink on Q1. Yet just as recently as a couple of days ago Ainslie still claims not to understand that the Q1 mosfet gets hot.

And as to the issue of the photographs and scopeshots I have posted...... have I wriggled enough, do you think? Have Ainslie's "appropriate departments" deigned to act in the matter? Are we sufficiently amused yet?

Is Ainslie ever going to apologize for the insults, lies and false accusations contained in this one single post of hers alone? It is to laugh.

Mark, you are going to have so much fun when she's on your forum...... I am really looking forward to seeing what she comes up with for you.
