The [[aeolipile]] represents the use of steam by the [[reaction engine|rocket-reaction principle]], although not for direct propulsion.{{Citation needed|date=February 2020}}

In more modern times there has been limited use of steam for rocketry – particularly for rocket cars. Steam rocketry works by filling a pressure vessel with hot water at high pressure and opening a valve leading to a suitable nozzle. The drop in pressure immediately boils some of the water and the steam leaves through a nozzle, creating a propulsive force.<ref>[http://www.tecaeromex.com/ingles/vapori.html Steam Rockets] {{Webarchive|url=https://web.archive.org/web/20191124015726/http://www.tecaeromex.com/ingles/vapori.html |date=24 November 2019 }} Tecaeromax</ref>

[[Ferdinand Verbiest]]'s carriage was powered by an aeolipile in 1679.{{citation needed|reason=Verbiest's car appears to use a turbine, not an aeolipile.  Motion is derived from the jet impacting upon a wheen, not from the reaction to the jet.|date=July 2020}}
