Remote Control invented

Nikola Tesla revealed a new invention at Madison Square Garden: a radio-controlled torpedo boat. It was the first demonstration of wireless remote control in history. Some witnesses believed that the Croatian inventor was using mind control. The four-foot craft, powered by onboard batteries, responded to radio signals through a complex mechanism Tesla developed using a device called a coherer. Despite the military potential Tesla envisioned, including guided torpedoes, his innovation was overlooked until remote control technology gained traction in the mid-20th century with the advent of rocketry and satellites.
