    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.

        Good luck running your steam engine without it!

        Its actually pretty common practice when restoring a steam engine to run it on compressed air to test it’s a ability to hold the amount of pressure it needs to. Much less of a catastrophic failure if compressed air leaks out without warning than 400° steam

        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.
