A brief synopsis - someone actually has an idea that might work -
Build an electrial system grid similar to the gas station grid - test it in closed markets - Israel & Denmark have serious investors - Hawaii is interested.
In simplified form - you buy car, some serious players working on cars - company owns batteries & electrical stations - When you go to get a charge, you can either charge the batteries in the car or get a new set if you are in a hurry - Economics are not worked out completely but I'm sure cheaper than any government mandate.
I like the idea of some test beds to see things work - I would think it would avoid the idiocy we call "Ethanol".
