Tesla At 75
On the occasion of his 75th birthday, Tesla talked about new developments.
"I am working now upon two things," he said. "First, an explanation based upon pure mathematics of certain things which Professor Einstein has also attempted to explain. My conclusions in certain respects differ from and to that extent tend to disprove the Einstein Theory . . . My explanations of natural phenomena are not so involved as his. They are simpler, and when I am ready to make a full announcement it will be seen that I have proved my conclusions.
"Secondly, I am working to develop a new source of power. When I say a new source, I mean that I have turned for power to a source which no previous scientist has turned, to the best of my knowledge. The conception, the idea when it first burst upon me was a tremendous shock.
"It will throw light on many puzzling phenomena of the cosmos, and may prove also of great industrial value, particularly in creating a new and virtually unlimited market for steel.
Tesla said it will come from an entirely new and unsuspected source, and will be for all practical purposes constant day and night, and at all times of the year. The apparatus for capturing the energy and transforming it will partake both of mechanical and electrical features, and will be of ideal simplicity.
Tesla has already conceived a means that will make it possible for man to transmit energy in large amounts, thousands of horsepower, from one planet to another, absolutely regardless of distance.
He considered that nothing can be more important than interplanetary communication. It will certainly come some day, and the certitude that there are other human beings in the universe, working, suffering, struggling, like ourselves, will produce a magic effect on mankind and will form the foundation of a universal brotherhood that will last as long as humanity itself.
He received birthday greetings from Sir Oliver Lodge, Ernst Frederik Werner Alex-Anderson, Lee De Forest, John Hays Hammond, Jr., Robert Andrews Millikan, Secretary of Commerce Robert Patterson Lamond, Henry Herman Westinghouse, and many another. Their greetings indicated the hope if not the confidence that "in a few months" or "a few years" the flame of Nikola Tesla's genius would weld one more astounding new device for mankind.
