I’m sorry but as a technicality none of the power used in a steam engine is derived from the dihydrogen monoxide. The chemical compound is used as a medium to turn thermal energy into kinetic energy. The thermal energy, likewise, is usually obtained from another source such as chemical, nuclear, or photovoltaic.





A steam engine can also be used to generate power, or to operate mechanical indistrial equipment like rock crushers or pumps, as a stationary device, but in hindsight the tidal power probably never gets that hot. The engine for moving trains could also be powered by electricity from wind or tidal, though I don’t think there are any practical examples.
