This is what his mother would call him, and according to David's recollection his mother told him that if she hadn't abused him so severely she would have killed him and buried him out in the backyard. It was only a very on the ball teacher that saw the plight David was in and reported the abuse.his is what his mother would call him, and according to David's recollection his mother told him that if she hadn't abused him so severely she would have killed him and buried him out in the backyard.

IMHO, AC Propulsion (Tesla Motors) uses AC because a mechanically commutated DC motor that meets the high turn down ratio of a vehicle application is more complex than an electronically commutated AC motor.
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages. Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer. The Tesla coil (L1, L2) , an air-core double-tuned resonant transformer, which generates the high output voltage. 2  Optionally, a capacitive electrode (top load) (E) in the form of a smooth metal sphere or torus attached to the secondary terminal of the coil.
