What Did Tesla Invent?

Tesla obtained some three hundred patents and provided our modern economy with electric motors, robots, remote controls, and radio.

This prolific maverick also foresaw cell phones, radar, laser weapons, artificial intelligence, the internet, and vertical-lift airplanes. According to the American Institute of Electrical Engineers, “Were we to seize and eliminate from our industrial world the results of Mr. Tesla’s work, the wheels of industry would cease to turn, our electric cars and trains would stop, our towns would be dark, our mills would be dead and idle.”
