2011 Chevy Volt - Click above for high-res image gallery

There are 16 days left in the month of December. Besides being time for most Americans to kick their Christmas shopping sessions into high gear and start planning their resolutions for 2010, it also means that there's precious little time for EEStor to "deliver functional technology" to Zenn Motors as promised.

Still, the promises held out by the secretive company are too great for us to forget about entirely. We'd love for EEStor's claims to be independently verified and proven accurate, as would just about anyone else looking to break free of petroleum in favor of electric vehicles, and that includes those waiting patiently for General Motors to put the Chevy Volt on the market.

This raises an interesting question: Could General Motors install EEStor's energy storage unit in the Volt? According to Volt vehicle line chief Tony Posawatz, it could happen, though "it would take couple of years." We certainly hope you're not holding your breath.

      EEstor is fake ABG, get over it.
      • 5 Years Ago
      I'm tired of Eestor getting any sort of publicity.They don't rate a mention. They've had every opportunity to deliver on their promises. If I was an investor I'd be worried.

      I have some beefs with that chart:
      Is the temperature effect on storage with lead acid really "very high" when Lion is rated merely "high". Let me put it this way: remember the Porsche Lion battery story a few weeks back? Where if it got cold you had to take your Lion out and put your lead acid back in? I think Lion has the narrowest operating range of any of the batteries on this chart, not lead acid.


      How does life reduced with deep cycle use interact with the one above it, cycle life? Aren't they both saying the same thing? Furthermore, is NiMH's life reduction with deep cycle used (listed as high) really the same as that of a Lion (also listed as high). In my experience, no. In my experience, NiMH (and even more so NiCd) really doesn't mind being run down and up as long as you keep the temperature in range.

      Okay, back to EEStor, this article sounds pretty accurate to me. EEStor has certainly underestimated the difficulty in taking capacitors to high voltages and keeping them there. And, like any other capacitor, the EEStor capacitors likely do not store 360,000x as much energy at 3600 Volts as they do at 6 Volts, not nearly so.

        Hi why not the LS2LS7, I don't mean to hijack this thread but you and David Martin were mistaken about the Tesla and it's charging capabilities. I am relieved to hear this from taxi.

        • 5 Years Ago
        Kinda tough to look at the owner's manual saying not to use certain charging settings or it will shorten pack life and to use the setting that cuts power output in half in order to preserve it and believe what Tesla is saying not to worry about the pack.
        • 5 Years Ago
        My problem with the chart centers around the fact that there are more kinds of LiIon batteries than there are verses in "American Pie", and they range in
        -price from 250 - 3000 $/kWh
        -cycle life from 400 - 10,000+
        -deep discharge tolerance from OK - Great
        -Energy density from 50 - 250 Wh/kg

      I think that for an electric car to be a success it take a small inboard gasoline electric generator plus a small but powerful battery. The volt is overbuild, too huge a battery and too huge the gasoline ice-electric generator and by the way too pricy. A simple battery is not enouph for any car because a small gasoline generator is cheap and efficient and add few cost to the overall package compare to what it add.
        • 5 Years Ago
        It's not an electric car if it runs on gas.

      No, not a nother deadline come and gone, No! Esstor, is there anything they can't do?

      Err ah, make a product?
        • 5 Years Ago
        Hey, EEStor has been missing deadlines since 2006, so why should they change now?

        Not only have they never shipped any product, they haven't even been able to make a tiny working prototype model!
      • 5 Years Ago
      Eestore is not the only company there are more ,the university MIT with there DESD technologie , The compagny Epod and there are lot more of nano technologi methods to get the job done.

      If the 52kWh EEstor unit was put in an Aptera 2e, the range would likely be between 430 and 520 miles! (Based on the Aptera battery being 20kWh yielding ~12kWh usable for 100-120 miles.)

      Sincerely, Neil

        Hi Chris,

        I did say "if" -- and of course the other big "if" is the Aptera itself...

        My point was to show that the Volt paired with a possible future EESU is not nearly as good as an Aptera with an EESU.

        400-500 miles of EV operation would be phenomenal; I think you'd agree?

        Sincerely, Neil
        • 5 Years Ago
        Except there are no "52 Kwh EEStor" available to put in the Aptera. Indeed, no one outside of EEStor has seen a single EEStor unit of any capacity, not even a tiny 10 watt-hour test prototype.

        EEStor talks big but produces nothing.

      Just a thought, but:
      For all the money GM spends on marketing the volt.
      And all the money they spend on lobbyists to get the volt considered for incentives.
      And in all likelyhood the money they spent lobbying the EPA to massage figures (I am thinking the dumb down of VW's TDI not them getting their own cars favoured)
      And for all the money it will cost for a complete retooling of the manufacturing and assembly facilities.

      Could GM have not simply designed a more efficient ICE. Not to sound like a fanboy of the euro's since Nippon Inc. (Japan) have some good tech also.
      The euro's really are on the cusp of some fantastic things. They have cars - not a car- carssss -plural - from many different co's -Renault, Citroen, VW, Fiat -that provide upwards of 50mpg.
      With all the tech advances due to come online or get perfected, in the next few years (direct injection gasoline, pneumatic valves, turbocharging, variable turbo's, inline turbocharging/supercharging, all that hydrogen storage tech to prevent the car from blowing up being utilized for NOS instead of hydrogen, ultrahigh pressure compression of air, all that hydrogen storage tech being used to store compressed air instead of hydrogen,) compression ignition gasoline engines, MY FAVORITE CAR DREAM ---alcohol fueled direct injection compression ignition dual inline ultrahigh pressure turbocharged pneumatically controlled valves regenerative braking system complete ICE shutdown when stopped torsen diff awd dual clutch 9sp transmissions

      ALL that tech is currently found in multiple models. (Not the 9sp, 7sp yes, 8sp in ltd)
      ALL that tech is road tested.
      ALL that tech will soon be integrated into ONE model.
      F1 cars sustain >18,000 rpm. Accurately referred to as high cylinder count, low volume cylinder, motorbike engines.

      And GM and the American federal government want me to drive an ultralow performance electric vehicle.

      If it were possible, it would be revolutionary. I think it is possible, but I kind of think the officers of Eestor have eaten the R & D funds and are looking for an exit strategy. Their modis operandi is a good clue. They were great at getting funded, but where is the product? Someone is going to develop practical ultracapacitors, probably with graphene guts, all in due time. It's a technology we desperately need.
        • 5 Years Ago
        That is exactly right. For now significant advances are being made in ICE technology. We need to transition to cleaner, more plentiful carbon based fuels with methane being the heir apparent in driving energy importation down to the point that the US is a net exporter instead of an oil junky. We have plenty of (cheap for now) natural gas to see us through to a renewable energy economy.
        • 5 Years Ago
        Unfortunately, there is no guarantee that any advanced technology will come along simply because we want it, or even if we desperately need it.

        If it does make it, fine, but until then lets use what we have now, and not wait for something that might never arrive.
      • 5 Years Ago
      This is clearly a scam. The claims are are almost identical as they made in 2004:

      According to a May, 2004 edition of Utility Federal Technology Opportunities, an obscure trade newsletter, EEStor claims to make a battery at half the cost per kilowatt-hour and one-tenth the weight of lead-acid batteries. Specifically, the product weighs 400 pounds and delivers 52 kilowatt-hours.

      They have known final configuration specs for nearly 6 years now, but they still have submitted a single cell as verification? They have continually promised this "next year". They have disallowed proper due diligence of investors.

      But I predict no one will be charged, they will eventually cite some technical hurdle they couldn't overcome, after who knows how many more years of milking investors.

      You may wonder how the pulled in hi profile investors? Simple greed is your answer. The payout here if this world changing technology actually lived up to claims is so astronomically large, that it shuts down the reasoning centers of the brain in some.

      I do hope we get resolution soon, this joke has outlived it's funny at this point.

        EEStor's production is reserved for Moller's Skycar.

        Yeah, that's the ticket...
        • 5 Years Ago
        Yep, just like Bernie Madoff pulled a fast one and scammed some otherwise bright investors...

        Dick Weir knows where dead bodies are buried, he use to work for the CIA, gosh darn it.
        What about all those load leveling patients he filed. That's what he does all night is write patents you know. All these things you can get right off the shelf, assembly lines are done. None of the ingredients are that expensive for this, you could get nearly all of it at a hardware store and industrial supply. 750,000 and he can be in production. All he is waiting for is his white powder and they will go into production. Locked Marten loves him. Zenn, well they don't make cars no more. Dick Weir is my hero. Not!

        I listened to a interview of Dick Weir a few months back. He knows just what to say.
      • 5 Years Ago
      You are forgetting that EEStor is closer (on paper) to producing the EESU battery than ever before. It will take just a few more (pick one)

      1) Days
      2) Weeks
      3) Months
      4) Years

      to get it working. I for one will be up late December 31st looking for the news release about the delay. I know of no other better reason to get sloshed on New Years' eve. :-)

        • 3 Years Ago
        2010 has past, 2011 has past, 2012 has arrived without news about EESTOR or EES and the very newest electric cars are still being equipped with nickel or lithium batteries, still needing overnight recharge and still causing "range anxiety". Si I pick 4
