I like O'Brien stories. It seems to me like he is keen on getting news of alternative energies out into the mainstream.
I've located a bit more web info on Marc Geller. First, he's a photographer and here's his website: http://www.marcgeller.com. Second, here is his blog about plugin cars.
Third, he links to Plug In America which will tell you all about plugin vehicles along with a bit of grass roots political action you can take to support them. There is a petition addressed to Automakers to tell them you want plugin technology. See also, the Electric Auto Association.
It looks like there is alot of activity on the website and alot of big names being drawn in. It will be great to see if some of that crowd is following the EEStor story and I would really hope they leave a comment here on this post with any additional information they have for this readership.
