Nikola Tesla’s work at Niagara Falls was a world-changing milestone that effectively won the "War of Currents" against Thomas Edison's direct current (DC). In 1896, Tesla, alongside George Westinghouse, harnessed the massive power of the falls to create the first large-scale hydroelectric power plant. While Edison’s DC could only transmit power about 100 yards, Tesla used his patented Alternating Current (AC) system to transmit electricity 25 miles away to Buffalo, New York. This was the first time in history that high-voltage electricity was sent over a long distance for commercial use. This achievement proved that AC was the superior method for powering modern civilization, setting the stage for the global power grids we use today. A bronze statue of Tesla stands at Niagara Falls today, commemorating his vision of "harnessing the wheelwork of nature" to serve humanity.
