Did 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

GM: Volt plus EEStor could work ... if EESU worked

How 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 ZE

REPORT: Zenn cancels plans for high-speed EV, will focus on supplying ZENNergy Drive components

According to reports from Reuters and GM-Volt.com, Zenn Motors has canceled plans to launch its cityZENN high-speed electric car and will slow down work on its low-speed EVs. According to Zenn Chief Executive Ian Clifford, the company will focus its efforts on becoming a supplier of ZENNergy Drive electric vehicle drivetrain components, which we assume will center around the EEStor energy storage system. Why the change in plans?

REPORT: 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

EEStor 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

ZENN: 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 t

EEStor gets patent for EESU, we get some details

Stop the presses! We've finally got some real information regarding EEStor's highly secretive capacitor-based energy storage system, though it's not exactly coming from the company itself. It seems that EEStor recently filed for patents of its new technology, which centers around a core of aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix, and they've now been granted those pa

Is production of EEStor ultracapacitors being pushed back into 2008?

After having earlier proclaimed that they would have their remarkable new ultra-capacitors in production this year, it now looks like EESTor is delaying production for as much as six months. CNET actually managed to talk to EEStor CEO Richard Weir on the phone and he said that production would start sometime before the middle of 2008. EEStor was supposed to deliver 15 kWh energy storage systems for installation into a new EV made by ZENN.

E tu Zenn? Advertorial messaging in the EV world

What is it with small electric car companies and paid promotion? We just took a look at Zap's somewhat questionable dealings with the website RenewableEnergyStocks. And look, here comes Ian Clifford, Chief Executive Officer of ZENN Motor Company in an interview on WallSt.net, something ZENN is paying WallSt.net's parent company, Financial Filin

Zenn buys into ultra capacitor company EEStor

ZENN Motor Company has paid $2.5 million for a 3.8 percent equity stake in ultra capacitor developer EEStor. The deal means that ZENN gets an exclusive deal for EEStor's batteries for small and medium sized vehicles. EEStor is going to use the money to fund the next stage of testing of their capacitors by an independent third party lab. If the capacitors meet the requirements laid out in the equity agreement, then ZENN will have the option to invest another

EDTA Conference: Secret effects of EESTOR ultracapacitor info from ZENN Motor CEO

At the end of the day yesterday, I snagged a few minutes with ZENN Motor Company CEO Ian Clifford by the EDTA Conference refreshments table and posed the question that Darin left in the comments when I asked what readers wanted to know more about: what's up with this secretive EESTOR ultracapacitor?
