Well, the problem is, they could buy the ingredients.

Their first milestone, making barium nitrate at 99.9995 purity took them a year. You can buy it, and have it overnight from Aldrich Chemical, or any number of chemical houses, its very popular.

Then, they took another year to make Barium Titanate. There is a multi-billion dollar industry that uses ultra-pure BT. There are a dozen MLC manufacturers in the US alone that buy the stuff from 3 major manufacturers. Google the chemical yourself, and see.

So, why?

I am a Zenn stockholder, who is frustrated by their lack of attention to the details so many people know. Why cant they come out and address the apparent problem?

Why dont they respond to my and another person intimate with the details of BT dielectrics? We wrote letters with references, and evidence, but not even the courtesy of a reply.

Is there not a contradiction here?

In the WIPO patent that the hype-believers are quoting, they already reached the target permittivity and voltage coefficient…what did they do with that powder?

It took them two years to remake only the BT portion?

The results discuss the issue of purity but two remain. The focus on purity why? Is there a failure mechanism of their product that high purity is hoped to resolve? Do they have problems with cracking and delamination the same as other ceramic capacitors? Does their part short circuit the same as other ceramic capacitors? What is the highest repeatable energy density they have achieved? Proto-type cars use to be made from clay, looked pretty good for pictures but just for show…. So without some numbers about the storage and reliability… just a pretty car made from clay.

Seriously, are there any materials science engineers in the group — from academia or the private sector — who can chat with me the details in the release? E-mail me at tyler@cleanbreak.ca… cheers.

In today’s interview Richard Weir said very clearly that prototypes do exist and were tested, and the money raised recently is for a PRODUCTION line.

Over at BariumTitanate the mystery blogger has a short alleged interview with Richard Weir in which he says the purity announced is necessary to get the permittivity and therefore the claimed high energy density. Also that they are setting up a “production line”; whether that’s for powder production or device production is not clear.

None the less, a curiosity provoking discussion

Zenn issued a press release announcing that EESTOR had issued a press release.

There is an interview with Weir posted on Cleantech where he fails to state a concrete timeline for permittivity results or an actual product. But assures that it’s all real and certified (though what he is referring to as certified in unclear) and there is “no bullshit.”

I hope I am wrong but this seems like tapdancing.

Hehe

Nicely put.

Green Car Congress have some detail:

Orion thanks for explaining this in layman term…

What it means is that one of their key pre-production benchmarks has been met. The 3rd-party company examined the material and processes for making that material they need for building EESUs and agreed it looks OK.

To make a cake you have to have flour, eggs, milk, baking powder, etc. EEStor is a bakery that can’t go out and buy these ingredients at a store, they have to make their own because no one sells them. The 3rd party has said, “Yes, this is cake flour, milled to the specified conistancy and made of the type of wheat specified for this job: These eggs are of a size and quality specified for making the cake according to the recipe, This milk is of the required purity, fat content, and lipid density, etc. They have all the ingredients and equipment for baking the cake according to the recipe. What the 3rd party review can’t tell us is if the cake recipe is any good or not. For that we’ll have to wait until they actually start making cakes – EESUs.
