Summary

Description
English: Diagram from Thomas Edison's 1891 patent of his wireless ship communication system. This proposed using vertical wires suspended from a ship's mast to communicate radiotelegraphically with nearby vertical antennas on shore. This predated by 3 years Guglielmo Marconi's first radio communication experiments. However it was designed to work by electrostatic induction, not radio waves. It was never tried, as Edison was too busy with other projects.
