No, I don't wish that, I know that

Frequency dependent.....He must not have spent the last 4 years working on a DC capacitor. Imagine that.....this invalidates about 65 gazillion posts from some skeptics I know.

This world shaking Linked In profile update can only mean one of two things: EEStor is done or EEStor is done.

Dave,

You clearly see the world in black and white - for you investigating frequency response clearly means Pettey cannot be doing any work relevant to DC!!

For some years ee-tom has been pointing out that if DW's EESU works then DW can make a lot of money by selling the product into the standard capacitor marketplace, some of which requires that the capacitors perform well at high frequency. So there is at least one commercial reason to do this stuff.

The other reason that AC measurements are good is that it enables you do something called impedance spectroscopy. This lets you work out some of what is going on inside a capacitor just by measuring its frequency response. It tells you things you would like to know even if you are only using it in DC mode.

What TP says is true of course. And it is even reflected in Pettey’s CV

Created testing protocols for the frequency dependent electrical properties of thin films.


Initiated impedance spectroscopy measurements of the dielectric properties of doped ceramic powders.

But I found this interesting because it makes clear that the ‘frequency dependent’ properties did not just relate to the CMBT. As TP states, such measurements would also be useful if made on the entire capacitor. But why be redundant in your CV about this (unless it is not redundant)?

From Impedence Spectroscopy

Impedance. The ratio of a sinusoidal voltage, applied across two terminals of a measurement cell, to the sinusoidal component of the current flowing between the terminals that results from the applied potential difference. Unless the system is purely resistive, impedance is a complex quantity because the current will have a different phase from the applied voltage: Z = Z' + iZ"

Also see Electrochemical Impedance Spectroscopy Primer.

I agree that there is no simple black and white to this.

Hi Pete, In medicine when we hear hoof beats we don't always think of zebras, our world is quite nuanced; as is the story around EEStor. I realize that there are possible explanations for AC testing of capacitors, but the interresting thing about this item from LPs' resume is that he mentioned it specificallly and that he referred to thin films specifically

Although you can create an explanation for this around the idea that he is testing a capacitor, there other possible explanations for this that I find much more interresting.

In particular, this: http://en.wikipedia.org/wiki/Resonant-tunneling...

"Resonant-tunneling diode (RTD) is a diode with a resonant-tunneling structure in which electrons can tunnel through some resonant states at certain energy levels. The current–voltage characteristic often exhibits negative differential resistance regions.
All types of tunneling diodes make use of the quantum mechanical tunneling. Characteristic to the current–voltage relationship of a tunneling diode is the presence of one or more negative differential resistance regions, which enables many unique applications. Tunneling diodes can be very compact and are also capable of ultra-high-speed operation because the quantum tunneling effect through the very thin layers is a very fast process."

It seems clean to me that Lucas is using linkedin for networking purposes. If he were looking for a job I doubt he would be using linkedin in order to attract employers. His level of experience is at such a high level and his expertise is such a niche that he would not need a job board to find work.

On the other hand if DW is trying to keep things hush hush this is certainly not the way to go about it.

i was out last night with a few friends doing some catching up. My close friends are a pretty diverse group and we include a couple of lawyers, a communications/software guy, a doctor , a truck driver, a retail camera store owner. i posed the question about why update your linkedin profile.
The answer was for a professional its better than facebook to let all those from highschool, childhood friends etc know of your accomplishments. Kind of like "see what i did!" and he wants everyone to know his role in this game changing tech.
i don't know if this has any bearing but it was something i had not thought of.

It will be interesting to see if he changes his profile of Monday after DW gets wind of it. If AHBL is far off than DW might tell him to take it down.

Acted as point of contact between pilot plant technicians and the engineering team.

Prepared bi-weekly quality control reports.

This was when he was at NASA/The University of Central Florida, not EEStor.

hopefully he will be looking for a job soon, since he may have finished his part in his current job.

He is R&D manager to take the prototype to pilot line. If the pilot line works then yes he is done. He may be indefinitely retained as an consultant and friend.
When Zenn gets the EESU and tests it then they may start the process of waking up.

I think 'If' would have been a better first word for this sentence.

One has to ask, too, whether a company that is content to sit around for years and years doing absolutely nothing whatever to earn money for their shareholders has sufficient 'get up and go' to be able to exploit this development, should it finally actually happen. It looks pretty well moribund to me.

He didn't list his musical exploits... How sad! :)

Skeptics should stock up on strong detergents for their pants for the reveal.

Each month, Dick Weir moves 50% closer to his goal.

This means he will never reach it. Is that what you meant to say?

I am sorry you think your glass is half empty, I did fill it up halfway. Should I have made more foam?

What a brilliant way to bring us and potential investors up to date without creating a media circus.

Maybe LP just signed up for linkedin so he could be a part of the "Polymer-based nanocomposites" discussion group. That seems to be the only group he belongs to.

I have never posted my info on LinkedIn so this is probably kind of a dumb question. So how hard is it for anyone to post a fake LinkedIn profile of someone else?

Technically it would not be difficult to force someone's LinkedIn entry, but it rather depends on whether you are willing to spend time in jail for fraud after the event. You have to attach at least one email address to it, but can't remember any other security requirements.

In this particular case it would be picked up pretty quickly as Tom Weir would probably be interested enough to have a read and would be likely to discuss it with Pettey.

It's highly unlikely Pettey's CV on LinkedIn is forged - too much of a professional job.

Thanks for giving me an answer. Is there anyway of telling how long his info has been posted on LinkedIn or when the Zenn info was last added or updated?

Congratulations, 'Po! You finally figured it out. And it only took you, what, three years and 5200+ posts?

Point of information, Mr Chairman. Under groups he also has the entry "Chaddick Dance Theater, President of the Board of Directors"

At UF, her choreography was featured in faculty showcases, American College Dance Festivals, and was awarded various scholarships including the Most Outstanding Senior. Through intensive summer workshops, she was able to attend the Alvin Ailey School, and work with companies such as Bill T. Jones, Shapiro and Smith, ODC San Francisco, and the Chuck Davis African Dance Ensemble. Since moving to Austin, she has become a certified Pilates Instructor and has performed her choreography in town for Dance Umbrella’s 10 Minute Max, and for Kathy Dunn Hamrick’s Annual Book & Dance Affairs. She has an amazing husband, 4 big rescue dogs, and is thrilled to be a part of this fabulous dance company!

I think looking at the antics of employees in the hope of deducing if anything is likely to happen is on a par with going through the company's trash bins.

Bit pathetic if you ask me.

oh, yes tec, I also found a perfectly good, partially eaten ham sandwich
