Tesla sitting near his transmitter in Colorado Springs…
Tesla sitting near his transmitter in Colorado Springs. The device was capable of transmitting millions of volts of electricity over great distances without wires. The picture was taken in 1899. By the end of the 1890s, Tesla had come to the conclusion that it might be possible to transmit electrical power without wires at high altitudes. There the air was thinner, and therefore more conductive. For nine months Tesla conducted experiments at Colorado Springs. Though he kept a day-to-day diary that was rich in detail, the results of his experiments are not clear. One question has never been definitively answered: Did Tesla actually transmit wireless power at Pikes Peak? A great deal of mystery still surrounds Tesla's work at Colorado Springs. It is not clear from his notes or his comments exactly how he intended to transmit wireless power. But it is clear that he returned back to New York City fully convinced that he could accomplish it.
