AddDid 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.

AddHow 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

AddREPORT: 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?

AddREPORT: 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

AddEEStor 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.

AddEEStor 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 patents. The best part for those of us who've been following the company's dev

AddZENN founder remains committedly-non-committal on EEStor

The Globe and Mail has published a online question and answer session between readers and Ian Clifford, founder of ZENN Motors. Aside from assembling a neighborhood electric vehicle in Canada, ZENN has garnered attention for its involvement with EEStor. The latter has made some big claims about a new ultra-capacitor it has developed. ZENN has made an equity investment in EEStor and has an exclusive license to use the energy storage system. The EEStor offers a lot of promise for lighter weight el

AddTechno Ride drives a Zenn, comes away impressed

TechnoRide, 'the car site for tech fans,' has managed to score a Zenn electric car for review. They seem to have had a good time with the NEV, calling it "impressive." They do, however, note a few issues with the vehicle, which are to be expected, including a lack of luxury features and excessive noise. The reviewer had no problem getting up to the Zenn's max-speed of twenty-five miles per hour and mentions that it's capable of more if it weren't for that electrically-limited speed regulation sy

AddZENN claims they will launch EEStor-powered EV in fall 2009

At ZENN annual shareholder meeting in Toronto yesterday, company officials made a big announcement about their plans to move beyond mere neighborhood electric vehicles. They plan to launch a model called the cityZENN which will be a fully certified electric car with 80 mph top speed and 250-mile range. The most important element of the cityZENN is the use of EEStor ultra-capacitors to store electrical energy. ZENN is claiming five minute recharge capability for the EEStor energy storage system.

AddIs 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.

AddE 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 Filings Corp., $280 to disseminate. They pay, and you still have to watch someone else's ad before you get to the site. Bummers.

AddZenn 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 $5 million dollars under the same term

AddEDTA 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?
