EEStory, new chapter but no prototype.

It has been a long time since I have written anything about EEStor. This week the true believers are in a new frenzie about EEStory. Yesterday EEStoroffered a press release.
EEStor, Inc. Announces Relative Permittivity Certification of 2009-04-22 19:49:36.589 GMT

CEDAR PARK, Texas, April 22
CEDAR PARK, Texas, April 22 /PRNewswire/ -- EEStor, Inc. announces relative permittivity certification of their Composition Modified Barium-Titanate powders. The third party certification tests were performed by Texas Research International's Dr. Edward G. Golla, PhD., Laboratory Director. He has certificated that EEStor's patented and patent pending Composition Modified Barium-Titanate Powders have met and/or exceeded a relative permittivity of 22,500.
EEStor feels this is a huge milestone which opens the advancement of key products and services in the electrical energy storage markets of today. The automotive and renewable energy sectors are a few of the key markets that would benefit greatly with the technology.
Company background
EEStor, Inc. develops solid-state electrical energy storage units (EESU's) in the form of batteries and capacitors. This technology has a wide variety of application use which includes with the added benefit of being longer lasting, lighter, more powerful, and more environmentally friendly than current technology in use.

Stocks in ZENN Motors, an EEStor play, have surged this week, even before the EEStor press release. I am struggling to contain my excitement. So far, I must say, I am still calm. EEStor still has not done a 3rd party test of the dielectric strength of its technology, and we have yet to see a working prototype. In the face of doubts, EEStor still has not brought home the bacon.

As I have noted before, EEStor is over a year behind the promised delivery date of a working prototype, and I do not expect one will be delivered this year. Or the next for that matter. None of the Doubts abour EEStir are going to go away anytime soon if ever.

My sceptical light is flashing. Relative permitivity numbers don't mean much unless you also know at what voltage they were measured. Standard barium-titanate dielectric has a strong negative voltage coefficient, so effectively the capacitor becomes smaller as the applied voltage increases. This really kills the energy storage. Dielectric strength is also a big deal, as energy stored goes up by the square of the voltage (assuming constant capacitance).

My guess is that practical versions of these capacitors are like practical fusion power -- only 10 years away (for the last 50 years).
