Skybird's video clip made me recall an idea I got a few years back, after having seen a documentary on Danish tv on and about batteries and electric cars.
My idea in simpel was that instead of all the charging stations they develop some kind of batteries that is light and with high capacity whether it's cold or hot.
The car owner just take out one of his batteri-In my idea a car has three batteries
One for the engine-the biggest in capacity
One for the AC - The next biggest
One for the electricity the lowest.
s/he takes out the battery replace it with a fully recharged battery and recharge the old one in his home.
When taking a long trip s/he could have a few batteries with them as reserve.
