Little known fact.

Detroit is known as the Motor City because for many years "ALL" electric motors where made here.

Edison, GE, and thousands of other companies produced Billions of electric motors here, at one time every industrial block had several motor manufacturers.


Consider...
How many electric motors are on the average automobile today?


Consider...
Automobile manufacturers such as FORD, GM, Chrysler, etc, made/make a percentage of their income selling direct current electric motors.
