Let Us Experience Wireless Electricity! ? A Dream Of Nicola Tesla
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high-frequency alternating-current electricity.
Among his numerous innovations, Nicola Tesla dreamed of creating a way to supply power to the world without stringing wires across the globe. The inventor came close to accomplishing this when his "mad scientist" experiments with electricity led to his creation of the Tesla coil. The first system that could wirelessly transmit electricity, the Tesla coil was a truly revolutionary invention. Early radio antennas and telegraphy used the invention, but variations of the coil can also do things that are just plain cool ? like shoot lightning bolts, send electric currents through the body and create electron winds.
In 1899, Tesla?s big dream was wireless power. Tesla had already demonstrated wireless transmission of power over small distances in his lab. Now, Tesla imagined constructing special stations which would send electricity and communications to the entire globe, an idea he called the World Wireless System
World?s largest Tesla coil
The largest Tesla coil ever built, 49.25 feet (15 m) in diameter,[which was a preliminary version of the magnifying transmitter was planned for installation in the Wardenclyffe Tower.
Tesla told reporters that he planned to conduct wireless telegraphy experiments, transmitting signals from Pikes Peak to Paris.
He produced artificial lightning, with discharges consisting of millions of volts and up to 135 feet (41 m) long.
Thunder from the released energy was heard 15 miles (24 km) away in Cripple Creek, Colorado.
People walking along the street observed sparks jumping between their feet and the ground.
Sparks sprang from water line taps when touched.
Light bulbs within 100 feet (30 m) of the lab glowed even when turned off.
Horses in a livery stable bolted from their stalls after receiving shocks through their metal shoes. Butterflies were electrified, swirling in circles with blue halos around their wings.
He was thus able to generate wireless electricity
Is the Tesla coil used today?
Tesla coils are a type of electrical circuit used to generate low-current, high-voltage electricity. Today, they're widely used in radios, televisions and other electronics, and can be used for wireless transmission
