The first trans-Atlantic radiotelegraphic message is sent from President Roosevelt to King Edward VII by way of the stations at Cape Cod, Massachusetts and Poldhu, England. It is not generally known whether the message was relayed by ships on the Atlantic or whether it was received directly from Cape Cod in its complete form. A station even larger than the one at Poldhu was begun in 1905, at Clifden, Ireland, and in 1907 this plant and a twin station at Glace Bay, Nova Scotia, were opened for limited commercial trans-Atlantic radio service.
1904
Thomas Edison is issued a patent for an “Electrical Automobile” designed with a driving motor that may be conveniently and effectively utilized for the purpose of charging the batteries.
