Nikola Tesla, aka “Mr. π / 2 ( c )”
v = π / 2 ( c )
v = average velocity of Tesla’s electrical current round earth (miles per second)
(you can plug in any metric and get same results)
c = speed of light (miles per second)
v = π / 2 (186,300)
v = 1.57 (186,300)
v = 292,491
While experimenting in Colorado Springs at the end of 1899, Nikola Tesla sent electrical currents around earth faster than the speed of light. In his patent No. 787,412, filed May 16, 1900, titled the “Art of Transmitting Wireless Electrical Energy Through the Natural Mediums,” Tesla expressed that the current of his transmitter passed around the earth’s surface and back to his reciever with a mean velocity of 292,815 miles per second. In his patent he says:
“The most essential requirement is that irrespective of frequency the wave or wave-train should continue for a certain period of time, which I have estimated to be not less than one-twelfth or probably 0.08484 of a second and which is taken in passing to and returning from the region diametrically opposite the pole over the earth’s surface with a mean velocity of about 471,240 kilometers per second [(292,815 miles per second)].” Charles Wheatstone first theorized this velocity, but many electrical experimenters have proven this velocity, including Jonathan Zenneck and Arnold Sommerfeld.
Tesla held, however, that our present “wireless” technology (ex. Internet, WiFi, radio, etc.) are not true Hertzian waves, but act more like sound waves. They travel close to the speed of light and are purely radiation while his energy transmission through the earth gives off no radiation because they are longitudinal current waves traveling through a conductor. Also, his energy is completely recoverable while today's wireless technology is not. It's like how the energy from your phone charger charging your phone is completely recoverable while the signals from your wifi router to your phone are not. This is how Tesla theorized that he could send any amount of electrical energy through the earth to power the world’s machinery and technology.
So… Mr. "π / 2 ( c )”, aka Nikola Tesla, was, and still is a mind far ahead of his time!
