Then he allowed them to look into the future, in which, within the lifetime of the younger generation he is convinced there will be communication among the planets.

Tesla Monument at Niagara Falls

“When I was 9 years old,” he related, “I built a turbine in a mountain stream on my father’s land and connected it up with bolts to all sorts of machinery. I told my uncle, ‘Some day I’m going to America and I will run a big wheel at Niagara Falls.’ I had read about Niagara Falls and it fascinated me. My uncle didn’t take it seriously. ‘You’ll never see Niagara Falls,’ he told me.

“But I did come to America, and I did put a big wheel in Niagara Falls.”

Dr. Tesla, at the height of his career, designed the great power system at Niagara, and perhaps no boyhood dream ever was more tremendously filled than his.

In the same interview, he also discussed life on other planets, stating:

“The inventor’s conviction of many years’ standing that there is life on other planets in the solar system and that some day we will communicate with other planets has not lessened. Means of communication will readily be found, he said, and there will be no difficulty in establishing an intelligent exchange of ideas. He indicated that this might be done through some sort of television which would transmit ideas much as moving pictures tell their stories to races of diverse languages.”

“I have a sense that we are on the eve of a great revelation,” he said, speaking of the possibility of interplanetary communication. “Whether I will live to see it is a question, but you, as a younger man, will see it. And the news of it will be the greatest sensation in the world’s history.”
