When George Westinghouse became interested in electricity, he quickly and correctly concluded that Edison''s low voltages were too inefficient to be scaled up for transmission needed for large systems. He further understood that long-distance transmission needed high voltage and that inexpensive conversion technology only existed for alternating current. Transformers would play the d
