Video: Edison vs Tesla — How Electricity Changed the World youtube.com

What if the way we power the modern world was decided by a battle between two brilliant inventors?

In the late 19th century, Thomas Edison and Nikola Tesla stood on opposite sides of a revolutionary question: how should electricity be generated and delivered to the world?

Edison championed Direct Current (DC), while Tesla’s Alternating Current (AC) system offered a powerful solution for transmitting electricity over much greater distances.

This documentary takes you through the key moments of the War of Currents—from Edison’s breakthrough incandescent lighting in 1879, to Tesla’s AC technology, the spectacular 1893 Chicago World’s Fair, and the Niagara Falls hydroelectric project that demonstrated the power of long-distance AC transmission.

This wasn’t simply a rivalry between two inventors.

It was an engineering battle that helped shape the electrical grid—and the modern world we live in today.
