Delays, hype, and more delays. This is the short history of EEStor, the company that keeps on talking about what is supposed to be an ultracapacitor that reinvents electric drive vehicle energy storage. Whatever is really going on, EEStor did put out a press release for Earth Day that keeps beating the hype drum. The announcement isn't about the ultracaps directly, but about EEStor's Composition Modified Barium-Titanate powders, which have apparently been verified by a third party to meet or exceed a relative permittivity of 22,500. The company says this "is a huge milestone" and that, "The automotive and renewable energy sectors are a few of the key markets that would benefit greatly with the technology."

For the non-technical among us (that would include me), let's ask Wikipedia what that might mean:

Permittivity is a physical quantity that describes how an electric field affects, and is affected by a dielectric medium, and is determined by the ability of a material to polarize in response to the field, and thereby reduce the total electric field inside the material. Thus, permittivity relates to a material's ability to transmit (or "permit") an electric field.

I'll leave it to our readers to tell us if that "relative permittivity of 22,500" is a big deal or not.
