Tesla promises Model S recharge 'faster than you can fill a gas tank'

I'm really curious about what they've come up with. The only practical way I can think to do this given what we have today is to swap cars.

  Or swap batteries. They could have stations ready with filled up batteries and swap it with the depleted battery. Elon alluded to it already: http://green.autoblog.com/2013/05/14/tesla-model-s-battery-swap-announcement-coming-soon/ http://green.autoblog.com/2013/05/14/tesla-model-s-battery-s...

    The current Model S, as far as I can tell, is in no way ready to do battery swapping in a reasonable amount of time. Could be, though; what do I know? EDIT: now that I look at the link you added, I stand corrected. From the exploded diagrams, et. al., that I saw it didn't look like it could be swapped out in five minutes. Tesla's designers obviously disagree. :-) And now that I view the link on a desktop browser, the one who posted it speculates that it's car sharing as well.

    The phraseology "recharge your model S" leads me away from the notion that it's it's a swap, perhaps they've found some way to treat the batteries as super capacitors?

I wonder if it's anything like Shai Agassi's vision http://www.ted.com/talks/shai_agassi_on_electric_cars.html http://www.ted.com/talks/shai_agassi_on_electric_cars.html

If this is possible, they should really look into installing their fill up stations at red lights in cities where Tesla is popular. These charge stations would only be active when the light is red and when a rechargable car is connected. The connector should be universal so any electric car can be charged. All vehicles including Tesla's would purchase a subscription to these passive charging stations, if they want to never worry about filling up in their city. This approach would allow a hybrid battery/capacitor approach, where the car keeps using the quick charge capacitor and only relies on the battery for longer distances and in places that don't offer the red light charge option.
