EEStor Patent Released

Here is the link to the EEStor patent released December 16th or two days ago. It clarifies a great deal and demonstrates a developing practice that fits the powdered and coated barium titanite protocol. The descriptions are also detailed enough to give one confidence in the numbers they are reporting.

It appears that they have actually made this device and it is working at the levels advertised. They may even have the manufacturing process settled down enough to make a bunch and to expect some reliability. It appears robust enough to handle vibration easily.

Folks have been responding to the claim that there are over 30,000 parts, but this sounds more like 30,000 micron sized barium titanite particles. Silk screening layers of such, multiple times, is hardly onerous.

This clearly describes what one would expect as the manufacturing system. It all depends totally on the capacity of each particle to absorb and to also discharge energy. Everyone wants to see that demonstration. It the protocol works, this patent convinces me that they can deliver sooner or later. After this we will see incremental improvements that moderately improve the system over the years likely by decreasing the size of the particle and sharply increasing the particle density. Yes, it can get better.

Take your time to read the patent and I don’t mean just the abstract. There is a lot of useful detail laid out in the description of the manufacturing process. I scanned the initial summary on the history of battery development but you may find it useful.

The energy separation caused by the use of coated particles makes this device safe so long as discharge is as easily controlled. One would hate to find a molten electric wheel in your parked car.

If this technology comes through, and from reading the patent and simply accepting the work clearly indicated, it has come through, then we have a real practical and compact energy storage device to work with from now on that clearly facilitates the electric car.

The patent is detailed enough for me to believe they have what they claim.

So the ideal car would use an EESU and a set of Michelin in hub motors

Since the energy in a capacitor goes as the square of the voltage used to charge it, then by increasing that voltage by 41.4% you double the energy stored and hence double the milage one can drive. It looks to me that such a voltage increase could easily be handled by an EESU, but then you are responsible for attempting such a trick!
