High Frequencies

“There is no subject more captivating, more worthy of study, than nature.  To understand this great mechanism, to discover the forces which are active, and the laws which govern them, is the highest aim of the intellect of man.” –Nikola Tesla1

After success at Niagara, Tesla began experimenting with high frequency electricity.  His initial experiments aimed to replicate sunlight and produce lamps of amazing brightness.  He also hoped to eliminate Edison’s inefficient incandescent light bulbs.  Tesla tried many different ways of stepping currents up to high frequencies and finally found the solution - the "Tesla Coil."  Using this new instrument, Tesla produced rudimentary neon and fluorescent lights and took the first x-ray photographs.  However, these advances paled in comparison to his next discovery. In November 1890,, Tesla illuminated a vacuum tube by transmitting the power through the air.2

“Exhausted tubes…held in the hand of Mr. Tesla…appeared like a
luminous sword in the hand of an archangel representing justice.”

– Remark from a reporter who saw Tesla’s demonstrations3

This remarkable achievement sparked Tesla’s lifelong obsession with wireless energy transmission.

“The economic transmission of power without wires is of all-surpassing importance to man. By its means he will gain complete mastery of the air, the sea and the desert. It will enable him to dispense with the necessity of mining, pumping, transporting and burning fuel, and so do away with innumerable causes of sinful waste. By its means, he will obtain at any place and in any desired amount, the energy of remote waterfalls — to drive his machinery, to construct his canals, tunnels and highways, to manufacture the materials of his want, his clothing and food, to heat and light his home — year in, year out, ever and ever, by day and by night. It will make the living glorious sun his obedient, toiling slave. It will bring peace and harmony on earth.” -Nikola Tesla4
