I have been browsing on-line more than 3 hours today, yet I never discovered any interesting article like yours. It is lovely price sufficient for me. Personally, if all site owners and bloggers made excellent content material as you probably did, the web shall be much more useful than ever before.

It sounds easy to buy Zenn right now, but if EEstor batteries are the real thing then Zenn will become a major player in the automobile industry. Maybe Zenn will buy GM!

if eestor is legit, gm will make a very aggressive bid to buy zenn out completely in order to get zenn’s piece of eestor. they know that they can’t buy out lockheed or kliener, but zenn they could get.

gm could still liscense the technology out to other oems, ala toyata with their hybrid system, but they wouldn’t do it right away, rather they would want 3-5 years after they introduced their own line of eesu equipped vehicles.

You guys are confusing volts with current in the charge-time comments. The charge will tranfer from the “toilet tank” at under 200V. The current will be Large, so thick conduits will be needed. 10000A would need around 3/4 inch dia copper cable or shuntbars for example.

From what I’ve read ZENN only has world wide rights to use the EESU in a specific class of cars. I think it’s determined by weight or maybe by maximum speed.

Matt,

Every article you write about the Volt is all the same: Here’s why the Volt sucks blah, blah, blah……
To say your reporting/opinionizing is not radically biased is hysterical. Bottom line is this, GM will be the first large OEM to market with a Eletric propulsed vehicle. If they want to run it off batteries(that exsist), ultracaps(which as of right now are farie tales), hydrogen(which you can’t get), or pig crap who cares. They will have the production facilities in place, ramped up to large scale, and have years of experience. The part your missing is the Volt isn’t about the Lithium batteries it’s about the eflex powertrain design. I was in New york at the Voltnation event and talked to Jon Launeker myself and asked him will the Volt ver1.0 be designed to have upgradebale batteries so the consumer can upgrade as the battery tech gets better. His answer was yes, as long as the new batteries can be shaped in the same physical dimensions as the origional ones. He also stated that GM wasn’t saying that it would be because of all the talk about supercaps and that eventually they might use a dual-stage li-ion – supercap battery which would obviously not fit inside the origional physical battery dimensions.

ps if you don’t know who Jon Launaker is you shouldn’t of wrote this article.

Is anyone privy as to who the third-party testers are? Southwest Research Institute verified the Barium Titanate purity a year and a half ago, but I can find no indication who is overseeing this next testing phase.

Whether or not the eestor ultra capacitor becomes a reality or over inflated hype remains to be seen.

As far as charing the capacitor in minutes, I belive the idea is to install the electrical equivilant of a toilet tank into your home grid. You need a second untracap that trickle charges over time off normal home power (something like 4-6 hours). When you want to charge your car, you “flush” your home-based ultracap at much higher voltages into your car.

As far as I know there is alot of research going into magnetic induction being used to charge EVs at high voltage as opposed to a direct connection in order to avoid the problem of HV electric arcs.
