when was the steam powered paddle boat invented
Steamboat The first steam-powered ship Pyroscaphe was a paddle steamer powered by a Newcomen steam engine; it was built in France in 1783 by Marquis Claude de Jouffroy and his colleagues as an improvement of an earlier attempt, the 1776 Palmipède. At its first demonstration on 15 July 1783, Pyroscaphe travelled upstream on the river Saône for some fifteen minutes before the engine failed. Presumably this was easily repaired as the boat is said to have made several such journeys.[6] Following this, De Jouffroy attempted to get the government interested in his work, but for political reasons was instructed that he would have to build another version on the Seine in Paris. De Jouffroy did not have the funds for this, and, following the events of the French revolution, work on the project was discontinued after he left the country.[7]
John Ericsson John Ericsson (born Johan) (July 31, 1803 – March 8, 1889) was a Swedish-American inventor, active in England and the United States, and regarded as one of the most influential mechanical engineers ever. Ericsson collaborated on the design of the steam locomotive Novelty, which competed in the Rainhill Trials on the Liverpool and Manchester Railway, won by George Stephenson's Rocket. In America he designed the US Navy's first screw-propelled steam-frigate USS Princeton, in partnership with Captain Robert Stockton, who unjustly blamed him for a fatal accident. A new partnership with Cornelius H. DeLamater of the DeLamater Iron Works in New York resulted in the first armoured ship with a rotating turret, the USS Monitor, which dramatically saved the US naval blockading squadron from destruction by an ironclad Confederate vessel, CSS Virginia, at Hampton Roads in March 1862.
