This is a very detailed technical writing of Tesla's major inventions, and it was published in 1894 by Electrical Engineer Magazine. If you want to really dig into the essence of Tesla's inventions this is a good source. The number of contributions he made to technology is incredible! This man was truly amazing and probably the greatest genius of all time. It's too bad he was such an eccentric and failed to share more of his work with his peers. Had this happened our world would probably be far more advanced technologically. But the works he did share drastically changed the world for the better. He is finally beginning to get the credit he is due. If he could have appropriately financed his endeavors, there is no telling what might have transpired.
