[NM020AAG], Technical Note, Thomas Alva Edison, May 6th, 1885
Editor's Notes
Dyer-- Take out patent for new method of telegraphing without wires especially available for communicating between ships at see across Rivers from Island to Island [drawings] You can telegraph from ships 24 miles apart when metallized strip is 100 feet from sea lever & then be 50 feet over the line of Curvature of the Earth [drawing] Spose two ships were 24 miles apart they could telegh & if there was another ship 24 miles further the messages could be repeated from ship to ship 1/2 way across the ocean-- at sea its very quiet & one only has to contend with the absorption due to the sea; & not to trees houses, hills etc
