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

System of Electrical Power Transmission

In an earlier patent, Tesla conceived of a method of combining multiple phases of electricity on a single transmission line. This probably led to what we commonly transmit: three-phase. In his patent for System of Electrical Power Transmission, he expands on that, creating a system of extracting those phases back out of the single transmission line and powering a multi-phase motor.
