Green stuff: Driven by Oil; EEStor super-batteries

Just caught a programme on BBC Radio 4 called Driven by Oil. The last part of a four part series on the oil industry, the final episode has writer/presenter Tom Mangold taking a look at (or, I suppose, a listen to) non-oil based forms of fuelling and energy for motor vehicles. Only half an hour long, and in spite of some slight naivete about plug-in electric vehicles, it's well worth a listen. The Radio 4 mini-site is here. If you're quick you may even be able to Listen Again to last week's segment before they update to this morning's programme - which is repeated on Radio 4 at 9:30 this evening.
Speaking of plug-in "ev"s (that's "electric vehicles", acronym fans; not to be confused with rv - which is an altogether different kind of American motor-dream), I don't know how I missed this initially, but I did:
Never-Ending Potency: Battery Replacement Could Charge Electric-Car Industry
This concerns an apparent breakthrough in battery technology using ceramics that originators EEStor claim could lead to mains rechargable electric cars with a 500 mile range from only "$9" of electricity. Even more impressive/significant/unbelievable is the kicker, where EEStor suggest a full charge would only take "five minutes". A completely fantastic achievement, or just completely fantastic?
Right now it's very difficult to know. Speculation has been bubbling about this company for some time, and there still seems to be very little in the way of actual answers. No major car manufacturers are involved at this stage, that's one thing for sure - but they do have other heavyweight investors. The technology itself appears to be based on capacitors, rather than a more traditional "battery" - not a new concept, but this would represent one of the first proper instances of implementation. I can't help but think that being ceramic, even if it is true it's going to be awfully heavy.... Canadian company Feel Good Cars, makers of the ZENN, above, are reckoning they'll have the tech on the road by 2008, however, so I'll just stand back and wish them luck.
Ignore the indecisive spelling of EEStor in both main pieces (and the typographic formatting war at the Giz), and the commentators at both Jalopnik and Gizmodo have some interesting things to say. I've listed a few other Google sourced references below.
