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 ...

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 ...

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. ...

Sun Microsystems founder Vinod Khosla has not been shy about making his bets on the automotive future known. Wherever there has been an opportunity to invest in or promote advanced ethanol, it seems Khosla was there, giving it at least a cursory look (see, for example, Coskata, which GM also ...

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 ...

EEStor, the company behind the ultralight, ultra-efficient – and ultra secret – EEStor Electrical Energy Storage Units (EESU) that could change the electric car world, still isn't giving out much information about their product. But Ian Clifford, the CEO of Zenn Motors, is ...

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 ...

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 ...

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 ...

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 ...
