42Report: EEStor invites U.S. government agencies to technology demo

In the realm of vehicle electrification, EEStor and its super-duper ultra-capacitors are roughly the equivalent of Duke Nukem Forever for video game players. The creators of both products have made impressive claims and repeatedly promised public demonstrations and introductions for many years. In both cases, the creators have missed every single promised date with nothing to show for it.

14EESTOR gets a bad rap (actually, it's kind of good)

Coming to you live from yesterday's EVCast, beatmasters Bo and Ryan have put together a mix using audio from the leaked audio of Dick Weir to highlight some of EESTOR's missed promises. It's got a beat, and the "jokes," such as they are, are really only for insiders. Still, if you know the history of secretive ultracapacitor company EESTOR and Zenn, then it's a good few seconds. Bretspot, the developer behind the amazing EESTOR timeline (above), has clipped out the song and made the short MP3 av

31Did EESTOR miss another deadline? Signs are pointing to "yes"

is it officially time to give up on EESTOR? Technically, we have 12 months to wait and see if Ian Clifford, the CEO of Zenn Motors, comes through on his promise to demonstrate the semi-magical-sounding energy storage unit in 2010. But silence from company that is partnering with EESTOR on the quick-charging ultracapacitor is lighting up the discussion boards over at EESTORY. It's not like the companies have a stellar track record of meeting deadlines.

15How can EEStor be valued at $1.5 billion?

We've long given up on waiting for announcements from EEStor (and, to a lesser degree, their partner ZENN) to come true. But, with the latest move by ZENN to drop their plans to launch the cityZENN high-speed electric car and will instead focus on becoming a supplier of ZENNergy Drive electric vehicle drivetrain components – ZENN's low-speed vehicles (pictured) have also been curtailed – the reality is that ZENN and EEStor are tied at the hip. As our friend Darryl Siry writes over at

30REPORT: public demonstrations of EESTOR's sectretive EESU next month?

Last month, we got a glimpse inside EEStor's ultracapacitor progress thanks to a leaked audio clip – admittedly, possibly on purpose – of someone interviewing EEStor CEO Dick Weir. At that time, Weir said that the EESU packs would be coming soon and promised demonstrations for 2010. We might not have to wait even that long for some sort of non-PR proof that the ultracaps work. According to All Cars Electric, EEStor has said, "they will prove their technology to the world by the end

26EEStor information overload (not a typo) in leaked interview with CEO Dick Weir

For about six hours recently, a leaked (we assume it was leaked) audiotape of someone speaking with EEStor CEO Dick Weir was available on Yahoo! video. Before the video was yanked, enterprising electric car fans managed to record the audio and have made it available around the net. What's amazing about this audio recording – and our knowledgable friends at EVCast vouch for its authenticity – is that for the first time, Weir is actually forthcoming with details about his company's EES

AddZENN: Trust us, the EESTOR thing is totally cool, like $700,000 cool

Hype maintenance can be hard work. Following the Earth Day announcement that the EEStor ultracapacitor had passed independent tests that showed it had a relative permittivity of 22,500, the automaker most closely tied to the secretive company, ZENN, has come out to say two things. First, the test results have been verified. There are a whole heap of details on the verification process in the release after the jump. Second, ZENN says that the results mean it will pay EEStor another $700,000 U.S.

AddHype maintenance continues: EEStor issues update, correction

Granted, the update and correction that EEStor released yesterday regarding their "huge milestone" Earth Day announcement aren't that major, but we can't ignore it at this point. First, the update is that the "relative permittivity certification" stuff was done at a temperature range of -20 and 65 degrees centigrade. The correction is a bit more information about the third-party verifier, Dr. Edward G. Golla, PhD., originally identified as the laboratory director at Texas Research International.

AddEEStor "permittivity" follow-up, by someone who knows (Daryl Siry)

Following EEStor's permittivity announcement on Earth Day last week, I wrote a post that ended with a call for our readers to determine if the stated "relative permittivity of 22,500" was a big deal or not. There were some educated responses (thank you), but one refrain that kept appearing was that everyone is waiting for a real and physical demonstration of the company's supposedly amazing ultracapacitor. "Until then," some of you wrote, "stfu EEStor."

AddEEStor comes up with an Earth Day announcement - it's "a huge milestone"

Delays, hype, and more delays. This is the short history of EEStor, the company that keeps on talking about what is supposed to be an ultracapacitor that reinvents electric drive vehicle energy storage. Whatever is really going on, EEStor did put out a press release for Earth Day that keeps beating the hype drum. The announcement isn't about the ultracaps directly, but about EEStor's Composition Modified Barium-Titanate powders, which have apparently been verified by a third party to meet or exc
