Early submarine. Historical artwork of an internal view of the Goubet submarine. This early submarine,built by the French inventor Claude Goubet in 1881,was designed for two people. It was battery-powered,had a Siemens electric motor for its propeller,and had a light mounted on the front. The operators could see through small glass windows using a set of prisms to see up,down and around. The first Goubet submarine was 5 metres long and weighed 6 tonnes. It was tested in the river Seine in Paris,France,but proved to be unstable in the water. Artwork from A Travers l'Electricite (G. Dary,Paris,1900) |
