Tesla believes in wireless energy. Through his experiments on radio and microwave, he thinks he can supply power to the city by transmitting electricity through the air. He didn't start building on a tower called Wardenclyffe Tower on Long Island. It was funded by JP Morgan Chase and used to transmit messages to transatlantic ships. However, once JP Morgan Chase seized Tesla's plan to supply electricity to new york through thin air, the funds were cut, and the tower was demolished several years later before it was even put into operation.
Tesla applied for a patent for a steam-powered mechanical oscillator in 1893. The machine vibrates up and down at high speed to generate electricity. Years later, he shared that when they tested the machine, it shook and everything in the room began to fly. He had to break it with a hammer. This caused a great commotion, and the police and ambulance rushed to the line of sight, but Tesla persuaded his colleagues to lie, just saying that it must be an earthquake.
Many of Tesla's inventions may be used as weapons, but he always believes that they can protect people and be used for peace. In 197, Tesla had an idea to use wireless telegrams to detonate explosives that would generate huge tidal waves at sea. Tesla thinks this will be a good way to stop any war.
Nicola Tesla believes that when a person thinks of something, they will create an image in their mind, which will be reflected on their retina. Therefore, he naturally tried artificial retina and tried to create a device that can capture these images.
Tesla has never stopped thinking about inventions. Even when he was 78 years old, he shared the news of his new ideas in the newspaper. He wants to speed up the production of mercury particles and make it 48 ties faster than the speed of sound to produce a powerful particle beam. He even offered this idea to many countries, but no one tried to test it except the Soviet Union.
