This is steam-powered mechanical contrivance allows the easy drainage of mines, among other tasks.
Practical “steam engines” that can do useful work offer many advantages over other sources of power such as animals and waterwheels. A beam engine that harnesses the pressure of steam to work a mechanical pump can be used to pump water out of mine workings either more efficiently or from greater depths. In both cases, the profits of the mine are greatly increased.
Historically, there were several almost-abortive attempts to create a “steam pump”, with most of the early efforts being carried out by engineers in Cornwall, England. This county was rich in many mineral ores, and landowners were prepared to pay handsomely for profitable innovations. Captain Thomas Savery (1650-1715) developed a “fire engine” that worked, after a fashion and as well as it could, given the time’s engineering limitations. It was, however, the beam “atmospheric engine” of Thomas Newcomen (1664-1729) that truly harnessed steam power and made miners’ lives safer.
Unlike workshops, mines simply add a large amount of fixed wealth to a region, yielding faster immediate returns. Unlocking this technology is a great way to give an early increase of wealth to the regions lucky enough to have mines.
Basic Steam Pump is a requirement for the much more advanced Steam-Pumped Land Drainage technology.
