Turbines have been used for centuries to covert freely available mechanical energy from rivers and wind into useful mechanical work or electricity. This is typically achieved via a rotating shaft. When the working fluid is water, the turbomachines are named hydroturbines. In coal or nuclear power plants, the working fluid is typically steam. Thus the turbomachines that convert energy from the steam into mechanical energy of a rotating shaft are named steam turbines. A more generic name for turbines that employ a compressible gas as working fluid is gas turbine. The turbine in a modern commercial jet engine is a type of gas turbine. In this talk, a brief introduction on such energy-producing turbines will be provided. Categories of turbines will be mentioned and their working principles will be explained. Of more concern in this talk is the efficiency of the turbine.
