Is a battery that is never used, still a battery? A battery is there presumably to be used. Avoiding going over a certain DOD, or firing up a gas or diesel generator occasionally to top it off, is all part of why they suck and why it's holding back off-grid and EV adoption.

ZENN, you may recall, owns a minority stake in Texas-based EEStor Inc., which is building a new energy-storage device based on ultracapacitor technology that could – if it works as promised – render conventional electro-chemical batteries obsolete. In addition to ZENN's 10.7 per cent ownership of EEStor, the company also has exclusive rights to use the technology in vehicles with a curb weight of up to 1,400 kilograms.
The Star in March 2006 was the first newspaper in the world to write about EEStor, which is partly funded by venture capital powerhouse Kleiner Perkins Caufield and Byers and has collaborated with Lockheed Martin to develop power-packed military weapons.

EEStor, the ultracapacitor company that has produced more obscure technology milestone announcements than evidence of a working energy storage unit, may have an implied market value of more than $1.5 billion.
The secretive startup in Austin, Texas, claims to have developed a new kind of capacitor that can store enough energy to propel an electric car 300 miles on a single charge. The company is not publicly traded, so investors who want to speculate on its “breakthrough technology” claims have only one way to get in on the action: Zenn Motor Company (ZNN: CA) That publicly traded Canadian firm, which first made an equity investment in EEStor in 2007, has upped its stake at each key milestone, culminating in a 10.7% ownership stake today. As a result, investors in effect get a small investment in EEStor as part of the deal.

Such bitterness


EEStor to ZENN: The CEO of electric vehicle maker ZENN, Ian Clifford, has been waiting for stealthy ultracapacitor company EEStor to deliver to Zenn its first commercial units by the end of this year, reported The Toronto Star in October. So? Well, we haven’t heard about that breakthrough yet and EEStor has been telling the media that 2010 is now the “make or break year.” Zenn has said it is basically betting the entirety of its business model on building vehicles around EEStor’s technology, so the milestone is kind of a big deal. Sounds like yet another missed deadline for the company.


Do you have flying cars there yet?
