Babelfish gave me this: http://tinyurl.com/yun7uf

Babelfish has improved a lot, most of the article is actually comprehensible.

Most interesting part to me. . . They are projecting 2/3 the volumetric energy density of li-ion. So hypothetically you could drop these into a Tesla Roadster and get about 150 miles range, lighter weight, fast recharge, and indefinite service life. Not bad.

However, it should be apparent that they don't even have a demonstrable prototype yet, and they are quite a few years from finding their way into products of any kind.

Much of the volume of Tesla Motor's battery pack is given over to cooling and other subsystems. I wonder whether a nano-capacitor of the same size would store the rough energy equivalent, such that the lower energy density is made up for by larger volume? Additionally, would it be possible to integrate safely a nano-capacitor into the core structure of a car? Given the capacitor's lifespan, you really wouldn't need to think about replacement, so they might go into some fairly unconventional places.

Hmmmmm

Hype-a-capacitor.

If it turns up for the start of the Auto X-Prize in 2009, fine.

At the same time I got that news article, I saw this one...
SoCal Heat Wave Strains Power Grid - Forbes.com
Makes me wonder about the impact of a couple thousand "fast charge" cars on the grid.

In certain areas it might pose a problem, but not necessarily. The way I imagine it, fast charge stations would charge a premium for the privilege, so only those who have to use them would do so. Most likely, these fast charge stations would not try to pull all that power from the grid at once, but would charge up stationary banks of NanoSafe's, or Ultra caps, or something at night at reduced rates. Then When you plug into the fast charge "pumps" you're pulling last nights energy from the batteries or caps. Maybe :p

I have always thought Tesla should be using the "dual" system of Ultracaps and Lith batts to reduce the strain of stop and go driving on the cars chemical based power source.

At the same time I know that Elon studied Ultracaps in college so I would think he would be able to look at the current technology and determine if it is ready for prime time yet.

Supercaps. The sexy science.
