So... are we just days away from all batteries and gasoline becoming obsolete?

Yes, I'm talking about EEStor, will they show the world a real ESU in September '09?

EEStor Awards Contract to Polarity Inc. to Produce EESU's Voltage Converter

By Lyle Dennis, Editor-in-Chief, August 26th, 2009

EEStor is the Texas-based company secretly developing an ultrahigh energy density, ultra-low cost, ultra-long -life new energy storage material that in theory would antiquate lithium-ion batteries overnight.

Not unexpectedly there is much hype, excitement and intrigue surrounding the company's 10 year private voyage towards unveiling an actual working prototype.

Reportedly they are nearing that climactic day and have publicity stated they will prove their technology to the world by the end of September, slightly more than one month from now.

Ten percent owner ZENN Motor Company (ZNN.V) certainly can't wait because they will be the first to receive delivery of these so called EESUs or energy storage units which will be placed in waiting ZENNCity electric cars.

Recently leaked audio of Dick Weir who is the co-founder of EEStor suggested the company was well on their way to success. "I know they are working hard!", says ZENN CEO Ian Clifford as of right now, referring to EEStor's race to produce their production EESUs.

In the leaked audio, Weir referred to a company in California called Polarity Inc. that is "actually putting the ZENN circuits together literally as we speak" to create ESUs for ZENN's cars.

Internet sleuth work of the EEStor blog has confirmed that company is called Polarity Inc. of Rancho Cordova, CA.

Confirming the audio's validity Polarity has published the following accomplishment on their website:

2009: Awarded contract from EESTOR to integrate Polarity’s high power HV to LV converter into EESTOR's EESU that will be used in Zenn Motor Company’s small to medium size electric car

Clifford has indicated the EESUs will have a native voltage of 3500. These converters will be used to step down the voltage into something more usable for vehicle applications, around 600 V.

Weir also said the Polarity circuits would be used for testing the components which are the building blocks of the EESUs as well as the EESUs themselves.

Well, stranger things have happened. :P

Sounds promising. Here's to seeing them succeed in this, and making it mainstream.

Gooooooooooooo Maxwell Labs!

Wouldn't it be fun to own an Aptera with an ESU powering it?

I wonder what kind of lead time Aptera would need to change from batteries to ESU, assuming the ZENN contract doesn't rule Aptera out.

after so many tons of "just around the corner" electric products get promised, but not delivered ... iduno ... forgive me but I must be getting jaded. btw speaking of which, after the last aptera delay was anounced months ago, wasn't the latest aptera promised date supposed to be coming up? Are we going to have to crank the calander back again? or, will it actually/finally happen this time ... anyone care to speculate?

Not really. I'm in the I'll believe it when I see it camp.

LightEVS Update


I spoke to Carl Watkins today. He was just back from a trip to Eurobike. Watkins indicates that since we last checked in, his firm has made contact with just about everybody in the ebike world including the major 3 wheeled vendors out there. There have been tons of inquiries not just about production availability and timing but also about whether or not LightEVS will one day IPO. For now, Watkins doesn't see a need to go public. Once a demo units become available, his feeling is, understandably, that those willing to be supplied EESU's will finance the lift off of his company.


For now, everything is in wait and see mode until EEStor makes it's next move.

*sighs* It's just hard to not be jaded... SO many things seem just off on the horizon-- yet that vanishing point never quite seems to get any closer.

Then again, NASA's announced making a mouse fly using magnetic fields, so I guess anything's possible now? Wonder why they didn't try a pig?

I'll believe it when I see it. Right now I'm skeptical.

I really do hope they're for real but I've heard about too many things like this that turned out to be nothing.
