Tesla invented one of the world’s earliest remote controls, which he called a “teleautomaton.” He patented his device in 1898 as a “Method of and Apparatus for Controlling the Mechanism of Moving Vessels or Vehicles,” which he used it to control a miniature boat from afar during a demonstration at Madison Square Garden.Īccording to the Tesla Museum in Belgrade, Tesla knew how important the invention could be, so he patented it in 11 countries as well. You can also thank Tesla for the ability to change the channel without having to get off the couch. “His patents and innovative ideas were milestones of wireless technologies,” said Ivana Zoric, curator at Serbia’s Nikola Tesla Museum in Belgrade.įor this and his other work, Zoric said, “Tesla is often referred as ‘The man who invented 20th century.” (Photo by Hulton Archive/Getty Images) Hulton Archive/Getty Images Italian electrical engineer and nobel laureate Guglielmo Marconi with the one of his wireless radio apparatuses. Unfortunately, Tesla and Marconi had already passed away by the time the court handed down their decision. In fact, the United States Supreme Court revoked Marconi’s radio patents in 1943 in favor of Tesla and two other scientists, Oliver Lodge and John Stone. The two inventors became embroiled in a patent war. Marconi is credited with sending the first transatlantic radio transmission, using technology from 17 of Tesla’s patents. History often touts Italian entrepreneur Guglielmo Marconi as the inventor of radio. Meanwhile, DC motors are still used for some industrial machines and conveyors, but often require more maintenance. Tesla countered by publicly shocking himself with 250,000 volts using alternating current to showcase its safety.īut Tesla had the last laugh, because today, alternating current is predominantly used to power most of the world’s electricity.ĪC motors are also used in refrigerators, power tools and fans. Edison even publicly electrocuted stray animals using AC power as a scare tactic.

“Tesla quit and he ended up in a battle with Edison,” Alessi said. But Edison never paid him the money, and claimed the promise was a joke. “He was working 20 hour days, and the whole time he was saying ‘let’s switch to AC current, it will work better,’ ” Alessi told CNN. With AC power, the current is reversed numerous times per second, making it easy to convert to higher and lower voltages.

Meanwhile, Tesla’s alternating current had fewer issues. This is the Tesla technology that sparked a war with Edison, the developer of direct current, and it’s the subject of the new film.īack in 1884, Tesla left Europe to work for Edison, who supposedly promised him $50,000 to fix the problems with DC power. We take a look at the most famous and important inventions that Nikola Tesla contributed to. Motors, radios, X-rays, neon signs and other technology was advanced by his extraordinary mind. “If Tesla didn’t accelerate the AC current system, we would be 50 years behind technologically than where we are today.”īut it’s not just AC power that Tesla worked on. Nikola Tesla's lab at Wardenclyffe in New York, which is being transformed into a science, education, and technology center.
