A steam turbine is a mechanical device that extracts thermal
energy from pressurized steam, and converts it into useful
mechanical work. It has almost completely replaced the
reciprocating piston steam engine (invented by Thomas Newcomen and
greatly improved by James Watt) primarily because of its greater
thermal efficiency and higher power-to-weight ratio. Also, because
the turbine generates rotary motion, it is particularly suited to
be used to drive an electrical generator, about 86% of all electric
generation in the world is by use of steam turbines. it doesn't
require a linkage mechanism to convert reciprocating to rotary
motion. The steam turbine is a form of heat engine that derives
much of its improvement in thermodynamic efficiency through the use
of multiple stages in the expansion of the steam (as opposed to the
one stage in the Watt engine), which results in a closer approach
to the ideal reversible process.
