In 1880, Alexander Graham Bell patented an optical telephone system called the Photophone. It worked by projecting voice through an instrument toward a mirror. Vibrations in the voice caused similar vibrations in the mirror. Bell directed sunlight into the mirror, which captured and projected the mirror's vibrations. The vibrations were transformed back into sound at the receiving end of the projection. He dreamed of sending signals through the air, but the atmosphere didn't transmit light as reliably as wires carried electricity.
