On the way to Colorado Springs, Colorado, Tesla first stops in Chicago, Illinois for his "Teleautomatics" address/demonstration before a meeting of the Commercial Club.
Tesla arrives in Colorado Springs to continue high-voltage/high-frequency experiments that had become too large for his New York lab. He stayed at the Alta Vista Hotel in room 207.
The first experiments in Colorado Springs Experimental Station were performed. Tesla records his initial spark length at five inches long, but very thick and noisy.
Tesla claimed discovery of a new geo-electrical phenomenon, which he said would allow for the transport of electricity around the world. Terrestrial stationary waves were first observed by Tesla and formed the basis for his wireless energy transfer plans and wireless communications.
Upon receiving a $100,000.00 investment from John Jacob Astor, Tesla promptly moved into the Waldorf-Astoria, which Astor owned. It was, at the time, the world's tallest building and is described as "extolling the essence of exclusiveness, cordiality, pomposity, and elegant grandiosity to the masses."
Working late one night on his powerful and sensitive radio receiver, Tesla observed strange rhythmic pulses on the receiver. He concluded that there was no possible explanation other than some effort was being made to communicate with Earth by creatures from another planet. Tesla reveals the discovery and is highly criticized.
