Steam turbine
A steam turbine is a machine that gets thermal energy from pressurised steam. It uses the energy to do mechanical work by rotation. It is usually connected to a generator to produce electricity. The heat to produce steam comes from burning a fuel such as coal, from burning trash in an incinerator, from the waste heat of other industrial processes, from a nuclear reactor, or from a natural source such as sunlight or geothermal heat.
