Why not create a modernized electrified highway. Then a large battery would not be needed for long distance travel. Consider a way to integrate a Maglev like electric supply system with an Interstate Highway. Rails wont work on the highway, but if you could make it a flat strip it might be possible that the EV could harness the power as it drives down the road with an arm from underneath the car that collects electricity. The arm itself could have a combination of magnets, sensors, and flexibility so that the car itself does not have to travel a perfect line down the road. Meaning people could still swerve a little and the car could still collect energy. It wouldn't change the way we drive. Just the power source we use to get from a to b. Pro- we could use Coal, Nuclear, Alternative, anything but foreign Oil. What do you think? Is it possible? I say it is possible today without any more advances in technology. It would cost a lot to build however.
