We need to probably trust that GM will only buy a product if it is of quality, but I honestly don't think that this technology for auto apps will be ready in the short term As I skeptical? yes. But I will wait and see before I form a proper opinion :) the interview does not give much away..I guess for obvious reasons.

Keep repeating : no prototype, no product. Repeat, repeat, repeat. Has Eestore applied for the government grants like A123 Systems ? Of course not, because in order to do that, they would have to have a demostratable product. The experts about ultracapacitors have spoken on these forums, and THEY have said it can't be done. And along comes Weir, with little training in ultracapacitors, and he 'says' he can make it work. The problem is........................... he still can't figure it out. The experts were right. Weir is just buying more time, and selling more smoke. Eestore should be forgotten about, except if you want a good laugh ! Weir is the Bernie Madoff of energy storage. Keep repeating : no prototype, no product. Repeat, repeat, repeat.

But I would not expect it for another decade or so. Actually, Lithium Iron Phosphate is the technology of choice... for now. Watch out for A123 batteries, Lithium Technologies or Tenergy. All are showing very promising results from battery tests. Again, I hope EEstor works...... but I doubt it will work for a while. I hope EEstor works.

Obviously, there is a very strict NDA, so Denise can't talk. GM would not have signed an NDA unless there was some interest. Denise would not have expressed There is no glint of information of whether GM has actually received a protoype or not. Because there still appears to be a relationship between EESTOR and GM, that implies that GM does see some potential , or else Denise would not have said they are keeping contact. I am highly skeptical of a seriously useful device/vehicle to come out of these discussions, but I'll wait and see. Remember way back when GM put millions into Wankel cycle engines, and never released a thing? Of course Mazda did, but it was not a game changer. I suspect this is just an updated replay.

It's so funny that people STILL beleive in Eestore ! It's hilarious. Weir is just sucking up the investment dollars, throwing a few tidbits out there to keep the whole thing rolling. But the fact is........he doesn't have anything. He thought he would. But he ran into problems, and can't solve those problems, hence the delays, and more delays, and no, absolutely no, prototype. He's stuck, he can't get it to work. The experts said it couldn't be done, and they know more about capacitors, than Weir. The only question left is; how long he can drag this out, and keep getting investment dollars, without really having a product that works ? Thanks again for a good laugh folks.

What if there is more to the story than just money. some people deserve the credit for sticking their neck out like Lyle. frankly im with tag, statik, and tim. Optimism sometimes makes life worth living. I taped a carrot to a horse once and made it look like a Unicorn. Was fun to see some eyes open wide at the site.

One of the most promising ones for EV applications is the split-pi converter. http://en.wikipedia.org/wiki/Split-pi. This is a long solved engineering problem, typical 200kW+ units mass less than 100 pounds. “I remember as a kid my dad playing with some kind of hardware(vacuum tubes) that produced 330 amps from a 110v source at 75 amps.
