Invention of AC Motor
One of the eccentric inventors at the beginning of this century was Nichola Tesla. Tesla's insight which led to the invention of the AC motor came to him as a sudden revelation.
Tesla was struggling with the problem for quite some time, when he decided to take a vacation with a friend. One evening while he was walking toward the sunset reciting a poetry to his friend, he stopped suddenly like a man in trance. The solution to his problem was in front of his eyes. He was dazzled by the clarity and sharpness of the image which appeared in his mind. His biographers described this experience:
"...the idea came like a flash of lightning and the solution to the problem of alternating current motors appeared before him as a revelation. He stood as a man in trance, trying to explain his vision to his friend... the image which appeared before Tesla seemed as sharp and clear and as solid as metal or stone. The principle of rotating magnetic field was clear to him."
All Tesla had to do was to run back to his cottage and make a sketch of his vision.
