The hyperboloid cooling towers are often associated with nuclear power plants, although they are also used in some coal-fired plants and to some extent in some large chemical and other industrial plants. Although these large towers are very prominent, the vast majority of cooling towers are much smaller, including many units installed on or near buildings to discharge heat from air conditioning. Cooling towers originated in the 19th century through the development of condensers for use with the steam engine. Condensers use relatively cool water, via various means, to condense the steam coming out of the cylinders or turbines.']}}]}, {'provenance': [{'wikipedia_id': '750772', 'title': 'Cooling tower', 'section': 'Section::::History.\n', 'start_paragraph_id': 5, 'end_paragraph_id': 5, 'meta': {'evidence_span': ['condense the steam', 'Cooling towers originated in the 19th century through the development of condensers for use with the steam engine.']}}]}]
