    drive EVs using a separate motor at each wheel, reverse polarity acting as the brake (for the most part, I think).  Just conceptual, as far as I know.

      a few years ago.

      Interesting stuff.
      I can't imagine you could get rid of real brakes --  you still need to stop when the power's out -- but still very cool.

      The small motors at the wheels are kind of interesting, but I wonder about the limitations.  Seems nice for a basic people mover, but how light can the motors be? Unsprung weight is the enemy of good handling.  Of course, 1500 lb of batteries is probably a bigger enemy.  Getting range with lighter battery loads would seem to be the biggest priority if electric cars are going to be more than around and about cars.

      Mind you -- there is nothing wrong with around and about cars.  That's most of the driving we do by far.  Heck, we tend to rent a car when we take a driving trip, so -- for us, an electric that could go a couple of hundred miles would be very attractive.

        drawback...maybe a transaxle motor, front and back?
