How Far Are We From Wireless Electricity?
The modern scientific revolution has reincarnated Tesla’s extraordinary idea which was once considered a pipe dream, and the prospects are incredibly appealing.
The year was 1891.
A little-known Serbian-American scientist by the name of Nikola Tesla designed a device that can produce and transmit electricity wirelessly.
The Tesla Coil was the prototype of a technology Tesla considered to be the holy grail of energy transmission.
The Tesla Coil
The Tesla Coil is an electrical resonant transformer circuit. It is a radio frequency oscillator that drives a transformer to produce high voltages at low currents.
The coil works through the principle of electromagnetic induction in which a conductor is placed in a changing magnetic field and produces a voltage across the conductor.
Tesla put out demonstrations showing how the coil could be used to wirelessly power light bulbs located meters away.
Even by modern-day standards, Tesla was way ahead of his time. But his ambitions transcended beyond the Tesla Coil prototype.
