Enter Tesla and Westinghouse
2. The Rise of Alternating Current
Now, let's switch gears to the other side of the equation: Alternating Current (AC). The main proponents of AC were Nikola Tesla (a former Edison employee, no less!) and George Westinghouse. Tesla, a visionary engineer, understood the advantages of AC for long-distance power transmission. His inventions, coupled with Westinghouse's business acumen, presented a formidable challenge to Edison's DC empire.
AC's secret weapon? Transformers. These nifty devices could efficiently step up and step down voltage, allowing for electricity to be transmitted over vast distances with minimal loss. This was a game-changer compared to DC, which suffered significant voltage drop over long distances, requiring power plants to be located close to consumers.
Westinghouse, realizing the potential of Tesla's inventions, bought his patents and began building an AC power grid. This directly threatened Edison's DC system, sparking the "War of the Currents." It wasn't just a technical debate; it became a heated rivalry, fueled by personal animosity and business interests.
Think of Tesla and Westinghouse as the underdogs, challenging the established giant. They had a superior technology, but Edison had the name recognition and the established infrastructure. It was a classic David versus Goliath story, but with electricity involved!
