> everyone will be plugging their car in at home

I realize that a lot of people here are privileged enough to own a single family home, but the majority of humanity lives in apartments and parks on the street. Trickle-charging at home is not a universal solution. The only practical solution seems to be some form of rapid charging of the car's energy storage. Either by pumping huge amounts of amps into a huge battery pack, or adding some kind of chemical fuel that gets reacted in an internal combustion engine or a fuel cell.
