Incredible Inventions of Nikola Tesla
by Donald Mitchell
Tesla has been praised as a genius by some scientists and denounced as a fraud by others. I trust the judgement of distinguished men who knew Tesla, granting him friendships and professional awards. Below is an article I wrote in 1972:
Nikola Tesla’s Investigation of High Frequency Phenomena and Radio Communication
Part I: The New York Lab
In 1887, Tesla began experimenting with very high frequency alternating current, and eventually developed the so-called Tesla Coil. This was a radio-frequency transformer consisting of a spark discharge oscillator and a tuned secondary coil.
Part II: Tesla In Colorado Springs
In 1899, Tesla built a 200,000 watt coil in Colorado Springs. Capable of generating arcs of up to 135 feet, he claimed it was tuned to a harmonic of the earth’s resonant frequency and had established electrical standing waves on the globe.
Part III: The Shoreham Transmitter
In 1900, Tesla began the construction of an incredible 200 foot coil with a dedicated powerplant. Tesla’s vision was far ahead of its time, including the concept of one-to-many broadcasting, radio navigation signals, encrypted communication, a broadcast time standard, and wireless image transmission.
