Water turbine took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" for "whirling" or a "vortex". The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of
Turbine-electric transmission ships instruments and applications. A lot of these electricity-generating turbines are being produced to include integrated electrical propulsion. A good example of one of these systems is the COGAL (combined gas and electric) system. An alternative approach is to use COGES, Combined Gas-Electric and Steam, to improve overall efficiency. A gas turbine-electric primary transmission is used, with a heat-recovery boiler in the exhaust flow to generate steam and thus electricity via a secondary steam turbine. Electric driven propulsion allows for movement of the ship and provides power generation on-board of the ship. Heat lost by gas turbines is not practical
