On June 30, 1908, a mysterious explosion shook the remote Siberian region of Tunguska.

The 15 megaton blast flattened 80 million trees across 800 square miles.

Every plant, every animal, every insect in the blast radius was vaporized.

The shockwave was felt as far away as England.

It looked like a comet impact, but no crater was found, no debris

was discovered. Scientists still can explain what happened. Well, except for one scientist, at the exact moment of the blast, on the other side of the world,

Nikola Tesla was conducting his latest experiment,

transmitting massive amounts of electricity through the atmosphere.

Tesla activated the generators in his lab.

His research station, Wardencliff Tower, fired up for one final dramatic test.

In an instant, millions of volts of electricity were sent into the sky.

Moments after the test, Tesla looked at the readings on his equipment.

He had one thought.

Oh no. Inventor, visionary mad scientist. Nikola Tesla is known for his groundbreaking ideas

that shape the world of science and technology.

Alternating current, which is the most efficient way of transmitting electricity long

distances? The AC of ACDC? That's Tesla.

Tesla also pioneered or invented devices like the induction motor used to power

machines like fans, conveyors, cranes, elevators, and more.

There's the Tesla coil, a transformer circuit designed to produce high voltage, low current

electricity.

He invented a radio controlled boat, the first RC vehicle ever.
