Changes

'''Steam Powerpower''' is an obsolete method one of the first methods developed for powering machines. It led to great amounts of , and sparked the [[industrializationindustrial revolution]]. It was developed early, but because precision machining and tight-fitting pistons are not required for building effective steam engines. Steam has been superseded by [[electricity]] and [[internal combustion]] as a method for some classes of powering machines, but remains important in others. Large stationery power plants, such as those used to drive generators in electric power plants, are often steam-driven, and, in fact in most nuclear power plants, the nuclear reactor boil water into superheated steam, which in turn drives the steam turbines which drive the generators.
