n. A system of angled and shaped blades arranged on a rotor through which steam is passed to generate rotational energy. Today, normally used in power stations.
n. turbine in which steam strikes blades and makes them turn
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 (1996) is by use of steam turbines. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic 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.

As he came closer, he could see that it had strong masts and a small steam turbine in the rear.
What had given him the idea for showing off the NIFTV when the Air Force was testing its APU was something he'd read about Charles Parsons, the English inventor of the steam turbine, who had used the celebration of the Queen's Jubilee in 1897 to arouse the interest of the British Admiralty.
They're not talking here of such easy errors as 'It's perfectly safe', or 'The ones that growl a lot don't bite', but of simple little sentences which are injected into difficult situations with the same general effect as a steel bar dropped into the bearings of a 3,000 rpm, 660 megawatt steam turbine.
But you are never long on water, and you have to hoard the water to drive the steam turbine.
