Nikola Tesla's patents for aircraft, ships, railways, autos, and more

Electric Railway System

Electric streetcars were a common sight in Tesla's day. One major flaw in cars' systems was the rolling or sliding contact that transferred electricity from the lines to the car. In his patent for an Electric Railway System, Tesla proposes a form of wireless power transmission that is underground. The power is conducted down a buried channel in which the streetcar's J-shaped lead passes to pick up and transfer the energy to the car.
