What should be clear here is that the production of the EEStor nano capacitors represents a remarkable technical achievement and the test results published show they are standing up. I can see from the cloud of commentary that a lot of impatience is been expressed that is seriously misplaced. They have the brick. Building from that brick is challenging but I certainly do not see it as a deal breaker.
What you cannot buy is time. Everything takes time to get right. The brick of the computer was the first miserable transistor. Yet that allowed us to immediately imagine today’s technology. The only catch was that our imaginations needed thousands of man years of time investment.
These guys appeared to have produced a very specific device which can enable the ultra capacitor. I hope that they can deliver something in the next year and do that continuously. I just think it is a tough goal post and would not be disappointed if the ball were dropped.
This transcript is rough but a lot of specific information flows out that I certainly find convincing. It is worth working through since much will not be in news releases.

W: Well, ahh, the basic building block that we use here and that both Carl and I have extensive knowledge of is Composition Modified Barium Titanate powder.
Well known the best powders of the highest permittivity of any materials in the world. Although they have some very significant problems. And people tried for about 30 35 40 years to solve those problems by variety of techniques process and that stuff. Ahhh, but classically they never really took the full approach that we did to attack those problems on an individual basis as we go through a production process. We saw in the past what they did the ... take these constituients Barium, Titanium, Calcium, Neodymium, Manganese, Yittrium, Lanthium, Zinc and .. and put those into a ball milling system and ball mill these powders down so they get it into a reasonable size. And they would then take and calcine those and they would grow together, Very high temperatures and then they'd calcine them again ... but ... they'd ball mill them again. 1:15 They kept that process up until they got something that was half way decent. But still a looong long way from optimum. Ummm, in looking at that process if you make capacitors out of those materials, and this is were the guys in the industry they said well the voltage is such a deep problem. Well, it was for them. For after all they did not take the time to solve the technical problems properly. And therefore you apply a voltage to those type of powders and they lose permittivity over time. And also if you are very high voltage, you get what's called domain wall slippage and you lose all the permittivity.
