In 1894, Nikola Tesla walked out of the US Patent Office with a smile on his face. Witnesses say he yelled: "This will change the energy world forever." Patent #512,340 was a device so powerful it could cut every household's power bill by 80% overnight. He had spent years building toward this moment, after Edison stole $50,000 of his work and laughed it off as an American joke, after bankers fired him from his own company and forced him to dig ditches for $2 a day. He invited five investors to his lab: two bankers, two energy executives, and the president of a powerful power company. He demonstrated the device. He asked for their help. They smiled. They shook his hand. One week later, on March 13, 1895, his Fifth Avenue laboratory burned to the ground. Two hours. $50,000 in research, models, and blueprints, gone. "I am in too much grief to talk," he told the New York Times. "What can I say?" He never recovered. He died alone in a hotel room in 1943 with almost nothing. The power companies that buried his work built trillion-dollar empires. They thought the secret died with him. It didn't. Tesla had given the plans to the people of his hometown village in Croatia. For 78 years those villagers paid less than 20% of what their neighbors paid for electricity. Now a short presentation explains exactly how to build it yourself. Under $73 in parts from any electronics store. One afternoon. No electrician required. Watch it before it disappears again.
