I have seriously-critical objections to any casual idea that a very high energy/power concentration stored, can ever be made safely viable as a retrofit to "anything with four wheels". I teach auto diagnostics to techs in-shop, and, I currently support 91 shops. Whenever a very-seriously-compromised advanced engine processing system stops their diagnostic process, my supported shops call me in. Recently, an epidemic (16 cases in 2 weeks) of blown processors, actuators, software programs (although the hardware was still OK in one) at very high cost to the owners and shops had occurred in Austin Texas, (and elsewhere I am sure). These were all traceable to the misapplication of chassis grease, spark plug boot dielectric grease, and heat conducting grease between the battery post contact surface and the internal electrical contact surface of the terminal which contacts the battery post. Greases oozed out from all these surfaces and prevented the starter-motor-retraction voltage surge from being absorbed by the batteries in all these cases. (It turned out that a parts store chain had "upsold" those 99 cent packets of trailer-connector grease when selling 12 volt batteries, stating that "corrosion could be prevented"). The point here is that you can not have anything but a complete factory design of any power-related system without fiscal or safety disasters, and that any casual suggestion that ultracaps "can" provide any practical benefit to retrofitting "anything with 4 wheels" is 100 percent wrong. Marketing departments must be very careful what they do and do not promote. Marketing personnel whom do not closely refer to active technicians in their respective fields (for advice), cause for themselves, their companies, and the consumer, grave risk of damages, or at the very least, a delay or impasse to advancements in their respective fields and companies. GM wiring standards have relentlessly proven to me down through the last 37 years of working "hands-on" with them, that GM is the best when it comes to safety, PERIOD. If GM does the electrical designing, I am comfortable with it, which is why I am on the Volt waiting list, (and am in preparation of my finances 20 months in advance to afford the Volt or Volt SUV preferably).

Have they delivered? Have they delayed? Have they disappeared?

Now that the end of the calendar year is quickly approaching, any news from the EEStor guys? Have they delivered? Have they delayed? Have they disappeared?

I think it’s time for another article about this one…

We didn't get our 150Hrs stand-by Li-Ion battery time on our cell phones the day Li-Ion batteries were invented, it took some time (decades) to get to nowdays energy density. The very same thing applies for capacitors. Different components give different specs. The former Ultracaps were using different insulators, which were not allowing for high voltages and caps were only growing in capacitence. Now nano-built tubes on surfaces would allow for great capacity and barium titanate would allow for very high voltages (7,000 volts and more) 3,500V limit is for our safety only. All there's left is get them off the conveyor with acceptably low deffects. You don't want an internal short to discharge an enire completly charged pack in an instant, that would rise the ambient teperature of your car with some 5000 degrees :-) This new nano-engineered Ultracaps is a developing technology.

This article is a joke right? Super Super capacitors? Sure. There isn't a single device in the world using this technology, but soon we will all be zipping around with these under our hoods. Lol.
