The storage device costs half of what the power train costs. Don't forget moters and electronics that charge and discharge the 3,000 volt capacitor.

Strictly from a marketing standpoint: wouldn't this technology be better introduced to the automotive world via a high-performance vehicle along the lines of the Tesla instead of a "feelgood" car?

Charles S

For $2000, I'd ask why only apply this initially for automotive applications? Why not also market it as home energy storage solutions?

There was a key sentence in the newspaper article that doesn't seem to have gotten much comment. It seems that eeStor doesn't use nano enhanced plates. It's tech is based solely on the dielectric material. This is the right decision (assuming you have the dielectric), but with available tech the effective plate area can be expanded by 10x to 20x. This yields 5x-10x more power storage. Thus, if the current product gives you 58 KWH, we now have 290 KWH to 570 KWH. Pretty stunning.

Good point Mike. I was thinking the same thing as I read the article.

Reminds me of two lead acid companies mentioned on this blog that have complementary technology -- they should get together.

I'm worried about something that will not Feel Good. What happens when a fully charged EEStor Cap develops an internal short, say due to a crash? Is this when your FeelGoodMobile is reduced to a bubbling pool of liquid aluminum, polymer degradation products and vaporized early adopters?

You have to keep wondering whether this is for real.....

Hi Charles S:

Could you please explain what you mean

"It's tech is based solely on the dielectric material. This is the right decision (assuming you have the dielectric), but with available tech the effective plate area can be expanded by 10x to 20x. This yields 5x-10x more power storage. Thus, if the current product gives you 58 KWH, we now have 290 KWH to 570 KWH. Pretty stunning."?

Thank-you!

EEStor supercapacitors only exist on the paper, unfortunately it won't work in reality. They are based on barium titanate, which has been used for decades in capacitors due to its high dielectric constant. However, this drops drastically in a high voltage electric field, such as the 3200 volts over 13 micron claimed in the patent.
This has already been pointed out by John on October 17:

It's too nice to be true!

As FYI: one of the first practical implementations of the portable audio electronics powered by Ultracapcitors (or Supercapacitors) instead of Batteries was introduced 10 years ago in the article titled:
Single capacitor powers audio mixer (Alexander Bell, USA, EDN, March 14, 1997, https://www.edn.com/archives/1997/031497/06di_04.htm). Hi-quality audio mixer powered exclusively by Ultracap, was capable of running for 2 hours on a single charge, while the charging time was as low as 10 seconds; the solution was recognized as the “Best Design Idea” by EDN Magazine.

Since that the author was actively promoting the idea of Capacitor-based Power systems, mostly for the portable devices (see the link to so-called “Green Electricity (GEL) Initiative”, now topping Google™ search engine): https://www.alexanderbell.us/Project/GreenElectricity.htm
https://www.alexanderbell.us/Initiative/GEL.htm

Another practical examples of using Ultracaps as intermediate portable energy storage in conjunction with muscle-powered generator is described in the article: Muscle power drives battery-free electronics (Alexander Bell, EDN, 11/21/2005. https://www.edn.com/index.asp?layout=article&articleid=CA6283833
).

Thanks for posting this article. I'm unquestionably frustrated with struggling to search out germane and brilliant commentary on this topic. Everybody now goes to the very far extremes to either drive home their viewpoint that either: everyone else in the planet is wrong, or two that everyone but them does not really understand the situation. Many thanks for your succinct, relevant insight.

Don't let newspapers or mail pile up as this is a dead giveaway that no one is home. One home security measure will not be enough to deter a determined intruder. Many burglars and other offenders do not randomly choose their victims.

one for all

I am following your blog regularly and got great information. I really like the tips you have given. Thanks a lot for sharing. Will be referring a lot of friends about this.
