Are we there yet?

I missed the big reveal end of 2009. Can anyone you post information on how the reveal went?

Reality check: wind power. A friend of my son talked us into helping build a 3 story home 40 miles up water on Rainey Lake in Canada. The battery they used for storing wind power was a fork-lift metal halide monster that was hauled in by snow mobile caravan. 5 years later and you need another caravan!!

On the one hand, EEstor has a good thing but on the other hand they lack facilities, are underfunded, understaffed, under water, and generally are in danger of redefining the Darwin award limits for stupidity. How long would it take at current trend to get that wind power monster replaced. How long would it take to put 700 million car systems in place at current pace. Never!! Every man, woman, and child in this country should be on the street with a placard protesting. They are literally killing millions of people by their foolishness; pollution alone is a cause for worry, lead, cadmium, carbon footprint, global warming can all now be placed at the door of EEstor unless they move like a bat out of hell. So I vote we give the thing to Dr. Ovshinky at Energy Conversion Devices or to GM as a cattle prod. To start, and despite being a staunch Republican, I vote we nationalize their sorry asses and put them all in prison until hell freezes over! (P.S. This is what is known as a negative motivational speech, positive hasn't worked very well.)

EESTOR-PUT UP OR SHUT UP!

This EESCAM debate can be easily settled. Enough of the press release, speculation, and news reports.

MR. DICK WEIR, DELIVER A PROTOTYPR OF THE CERAMIC BATTERY WHICH YOU HAVE PUBLICLY STATED HAS BEEN, BUILT, TESTED, AND CERTIFIED TO AN INDEPENDENT REPUTABLE INSTITUTION FOR VERIFICATION. WE HAVE BEEN WAITING SINCE 2001 FOR THIS CERAMIC BATTERY.

PUT UP OR SHUT UP!

fyngyrz, I think I'll go with "common sense" and "rational thought", over Zenn's posturing for venture capital and stock picks, thank you very much.

NC LLC:

a) Do you actually believe that Zenn would allow a milestone test that didn't measure a factor related to actual operation? Of course they checked it at the appropriate operating voltage. Zenn isn't going to give out 700k on the basis of a 1v test.

b) I'm afraid your claim of "impossible" looks pretty silly as these milestones are passed. Think I'm going to have to go with Zenn's need for due diligence over your... expertise.

Good job Rud, becuase of your comments given to B at theeestory.com regarding temps, they now determine that that is proof that eestor has what they claim, way to put the kabosh on that dude, nice job.

In order to store the amount of energy sought by eestor, its ultra capacitor must maintain its high relative permittivity at HIGH voltage. It has always been easy to measure a high relative permittivity of an engineered materials like barium-titanate at LOW voltage, but the relative permittivities of these materials dramatically degrade at high voltage because the high electric fields lead to permanent changes in the crystal structures of the material. This occurs even if the breakdown voltage of the material is not exceeded (eestor's previous milestone).

Unfortunately, the eestor press release did not indicate a voltage level for the measured permittivity, so we are still in the dark as to whether eestor has found the holy grail of electric energy storage.

This announcement must be read carefully. It is relative permittivity of the CMBT powder, not a component. The ASTM standard calls for 25C at 1 volt. This is not about a component, nor does it give the TCC, the VCC, or the breakdown voltage. It cannot, as that would require a chipcap component. Hanson's patent on which EEStor CMBT is modeled has data on permittivity up to 25700 in actual chipcaps. But these are Y5V class components, with TCC, VCC, and breeakdown voltages impossible for an ESSU.
