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.

He envisioned a world where all of humanity could have cheap, or even free electricity. He pushed boundaries to create something more functional in the real world.
