Our friends over at EcoGeek got an interesting little piece of video of Denise Grey, GM’s Battery Director, talking about communication GM has had with EEStor.

EEStor, for those who don’t know, is a curious little company out of Austin, TX that claims to have reinvented the electric car battery, or rather made electric car batteries altogether obsolete. EEStor’s invention is an ultracapacitor that can supposedly hold significantly more energy than a lithium battery, doesn’t degrade and is cheap to produce.

Hard to believe right? Well it’s even harder to believe considering there’s no sign of these EEStor ultracapacitors being produced, let alone some verifiable proof that a working prototype exists. I always assumed that most people just dismissed EEStor’s claims as ludicrous.

The above video shows Lyle Dennis from GM-Volt asking Grey about GM’s relationship with EEStor. Her answers indicate that EEStor might have some level of credibility that its didn’t have before since GM is lintening to what they have to say.

Although Grey says she can’t comment on whether she’s seen a working prototype or not, if you watch the video you see that it seems like she hasn’t seen one. But still, there does seem to be a relationship and GM hasn’t dismissed EEStor as a bunch of crackpots, so maybe there is something there.

I’m still skeptical but we’ll see. I’d love to be proven wrong about EEStor.
