Westinghouse-Parsons steam turbine. Diagram of a cross-section through a steam turbine of the Westinghouse-Parsons design. A steam turbine converts the thermal energy of steam directly into rotary motion, which can then be used to generate electricity or power a machine. This design is named after the British engineer Charles A. Parsons, who invented the steam turbine, and the US engineer George Westinghouse.
