-a steam turbine is a device that extracts ‘thermal energy’ from ‘pressurized steam’ and uses it to do ‘mechanical work’ on a ‘rotating output shaft’-
.
(its modern manifestation was invented by ‘sir charles parsons’ in ‘1884’)
(because the turbine generates ‘rotary motion’, it is particularly suited to be used to drive an ‘electrical generator’ – about 90% of all electricity generation in the ‘united states in the year ‘1996’ was by use of ‘steam turbines’)
.
(the ‘steam turbine’ is a form of ‘heat engine’ that derives much of its improvement in thermo-dynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal ‘reversible expansion process’)
