Harnessing Niagara: Tesla, Westinghouse, and the War of Currents
Harnessing Niagara: Tesla, Westinghouse, and the Electric War
In the late 1800s, electricity wasn’t just lighting up homes—it was fueling one of the most dramatic tech battles in history. On one side: Thomas Edison, the face of direct current (DC). On the other: Nikola Tesla and George Westinghouse, backing alternating current (AC). Cities were the battleground. Niagara Falls was the ultimate prize. This was the Electric War.
Tesla Meets Westinghouse
Nikola Tesla, a Serbian-born inventor with a mind like lightning, had a brief and stormy stint working for Edison. He believed AC was the future. Edison scoffed. So Tesla walked—and eventually found an ally in George Westinghouse, a successful businessman who saw genius in Tesla’s vision. Westinghouse bought Tesla’s AC patents and gave him the backing to bring the future to life.
Why AC Won
Alternating Current flows in a back-and-forth pattern, switching direction dozens of times per second. This makes it perfect for sending electricity over long distances with little energy loss. Transformers allow the voltage to be increased for transmission and safely decreased for home use. It’s flexible, efficient, and scalable.\
To put it simply:
DC is like water flowing through a hose in one direction—fine if the faucet is nearby.
AC is like the ocean tide—powerful, rhythmic, and able to travel for miles without losing strength.
That’s why AC could deliver power all the way from Niagara Falls to Buffalo—over 26 miles away.
Why DC Fell Behind
Direct Current flows in only one direction and fades fast. To power a city, you’d need a power station every mile—costly and inefficient. It also can’t change voltage easily, making it harder to transmit safely. Worse, DC builds up heat in wires, wasting energy and raising fire risks. Back in Edison’s day, these limitations made DC a dead end for large-scale power.
The Electric War Heats Up
Edison didn’t go down quietly. He launched a smear campaign, using grisly public demonstrations to portray AC as deadly—including electrocutions of animals. He even promoted the first electric chair using AC to associate it with death. He tried to turn “Westinghoused” into a word for being electrocuted. It didn’t stick.
Meanwhile, Tesla and Westinghouse focused on real-world impact. Their breakthrough came in 1893, when they won the contract to power the Chicago World’s Fair. The dazzling display, lit entirely by AC, stunned the public and silenced critics. AC had arrived.
Niagara Falls: The Dream Realized
As a boy, Tesla dreamed of harnessing Niagara Falls. “I will go to America and turn the power of the Falls into light,” he told his uncle. In 1896, he did exactly that. Tesla and Westinghouse were awarded the contract to build the first major hydroelectric plant at the Falls. Backed by moguls like J.P. Morgan and the Vanderbilts, they built enormous AC generators to convert the waterfall into energy.
On November 16, 1896, Buffalo lit up—26 miles from the Falls. It was the first city powered by long-distance hydroelectricity. Edison quietly began converting his systems to AC. The Electric War was over.

The Wizard of Niagara Falls
Though he helped electrify the modern world, Tesla didn’t end up rich. In fact, he tore up a contract that could’ve made him a fortune—just to save Westinghouse’s company from going under. In the end, Westinghouse thrived. Tesla didn’t. He died poor and largely forgotten.
Today, the electric car brand Tesla bears his name, and a statue of him stands on Goat Island, overlooking Niagara Falls. It’s a tribute to the man who turned water into light—the Wizard of Niagara Falls.

Pan-American Exposition: The Victory on Display
By 1901, Buffalo had become the “City of Light,” powered by the very Falls Tesla dreamed of. At the Pan-American Exposition, the city was ablaze with electric lights, all powered by the Niagara plant. The fair became a glowing monument to the triumph of AC power, cementing Tesla and Westinghouse’s legacy—even if only one of them lived to see the praise.

Fun Facts:
Tesla claimed to have seen a vision of a giant waterwheel at Niagara as a child. Years later, he made that vision real.
Edison tried to ruin Tesla’s name—but Tesla’s ideas outlasted Edison’s tactics.
The Tesla car? Yep, it’s named after that Tesla.
