Turbine waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to Swedish engineer Gustaf de Laval (1845–1913) for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the
Hector (steamboat 1897) with a new boiler was raising steam off Purdy Spit when an apparent coal gas explosion occurred. Harold Lanning was able to rescue the crew with his motor vessel. The burned hull of "Hector" was towed to the shore, where beachcombers eventually removed everything usable from the hulk. Hector (steamboat 1897) Hector was a small steam vessel built in Roche Harbor, Washington in 1897. The vessel was worked as a cannery tender and a tug boat in the San Juan Islands and on Puget Sound from 1897 to 1913. "Hector" was built for the brothers Capt. Thomas Gawley and Engineer
