This is a pretty neat idea, I do worry about the 'one and done' problem where the spinning flywheel charges a car and then then needs an hour to get up to speed again (more if its just using solar power). That means you either need a lot of flywheels to service cars.
It is also an amazing amount of energy to be holding in the box next to the car (if you can believe the artist's conception in the article). I would be much happier if they put the flywheel horizontal in a vault under the charging station, that way if a bearing failed the wheel wouldn't go careening off into the next county mowing things down.
This problem needs to be solved for electric trucks as well.
