On the existence of EEStor prototypes/permittivity

An alert reader/commentator on this blog uncovered some material he believes shows that EEStor prototypes exist...with permittivity tests to boot.  Thanks Jay.  Jay found this WIPO patent from 2006 and used it to create this spreadsheet showing permittivity data.

We just had this conversation at the end of a previous thread. Go check out the conclusion.

provided image is kind of misleading.

It is obviously related to some University method of permittivity measurements, NOT actual EESU unit.

Hey, I found that WIPO patent months ago and failed to find a good venue to publish it.

Finally entered the Blogosphere

For a somewhat prettier and more readable version:

Though the tables still need more beautification.

That was one common sort of thing that made that OCR'd WIPO document difficult to wade through. An the Blog software doesn't help with tables or exponents.

The last table in that Google docs spreadsheet - Voltage Breakdown - needs to be re-labeled. The units of measure are 10**6 (millions of volts, per cm). [The voltage ISN'T breaking down at 5 or 6 V / cm! :) ]

That picture is of a test stand setup from http://www.ipr.umd.edu/MPL/tour.htm

Is the implication that the University of Maryland's Institute for Research in Electronics and Applied Physics' Microwave Processing Laboratory for Advanced Materials is the third party testing the permittivity?

Nekote,

I had mentioned that you pointed to the WIPO application back on July 4th but I had to remove the post because of other errors.

Nice spot.
