Nikola Tesla - The Forgotten Father of Wi-Fi


This sounds like the Internet and Wi-fi world we live today being described here:
  • Secure government communications service
  • Voice communications around the globe
  • Universal distribution of stock tickers, news and weather
  • World musical distribution
  • Synchronization of clocks around the world with astronomical precision
  • Worldwide transmission of texts
  • Global positioning for navigators
  • World printing on land and sea
  • Worldwide distribution photos and drawings
Actually, in fact, these features came from a promotional brochure of Nikola Tesla's "World System" in 1906.

In 1900, Tesla began construction of a wireless broadcasting tower on Long Island, New York. Tesla intended to use it to link the world's telephone and telegraph and to transmit data. A lot of mystery and controversy came about Tesla's tower. It was never completed and was believed to have been sold as scrap metal during World War I.

Nikola Tesla (b. 1856), an inventor and a mechanical and electrical engineer, immigrated from Serbia into the US in 1884. He is quite possibly the one of the greatest inventors in modern history. But he is a virtual unknown in the textbooks and the general public.

He was the first to demonstrate wireless and long-distance communication via radio 10 years ahead of Marconi. In his lifetime, Tesla produced 800 patents and numerous inventions which include Alternating Current (AC) which is the basis of all electrical distribution as we know today.

He spent the last 10 years of his life living in a hotel room and died penniless. He tore up a Westinghouse contract that could have made him the world's first billionaire partly because of the implications that would have in his future inventions and his friendship with George Westinghouse. Thomas Edison spent the rest of his life trying to discredit Tesla in what was known as "War of the Currents".

Some of his ideas were so far-fetched during his time and people just didn't get it and considered him a mad scientist. Lacking money, he wrote his ideas in countless notebooks. However, upon his death in 1943, the U.S. authors confiscated his files, classifying them Top Secret, and they spent years making copies proving the value of his ideas. It is only now that his works are being appreciated and put into modern, useful technological innovations.

Here are some of this ideas way ahead of his time.
  • Remote Control. In 1898, Tesla demonstrated a radio-controlled boat to the US military, believing that the military would want things such as radio-controlled torpedoes.
  • Wireless Energy Transfer. Tesla was able to power 200 light bulbs without wires 26 miles away! Today, inductive coupling technology can wirelessly power toothbrushes, cell phones and gadgets.
  • Free Energy. Tesla envisioned using the earth and sun as renewable energy. Today, we have solar power and microwave technology.
  • Death Ray. Tesla designed a directed-energy super weapon using charged particles to project beams capable of destroying 10,000 enemy planes from a distance of 250 miles! In recent times, the US has delved into developing "Star Wars" weaponry aka SDI as Tesla substantively anticipated.
