   I knew it would come to this...
Lets see if we can find some perspective to place this in...
   As electric vehicles near production, the effeciency, size, and power-weight
 
ratio will lead to designing vehicles with motors at the wheels.  Either two
motors or four motors on each vehicle.
   Now let us look at a minimal electric vehicle with current technology.  
Probably a sub-compact with a strong light-weight chassis, a lot of light-weigh
t 
materials, batteries, and two electric motors on the rear wheels.  This would 
give it 40 Horsepower.
   How does this compare with current vehicles?  Hmmm..  I have a beat-up 1975
Mercedez 240D.  This is a compact car and fairly heavy.  The diesel engine is
a 2400 cc power monster with a whopping rated 65 horsepower.  Now, I use every
engine elixir I can waste my money on, so I am probably getting most of my
65 horses.  I am seldom left at the light by anyone (more of a tribute to my
wild diesel driving style.)  Most of us have been annoyed by diesels creeping
through the light ahead of us.  But these are often cars over 15 years old that
probably have barely over 40 horses left in their engines.
   Now lets compare this to our minimal EV.  We will have a car with Two thirds
the weight of my car powered by two thirds the horses.  This wouldn't change my
driving style...  I am looking forward to being one of the first people in the
world to get a deal on an early model Flywheel powered Electric Used car (Its
my style.)
   It all seems possible to me...  Ted..
