#steam engine
- Steam car — An archaic technical term used at the dawn of the industrial era to designate a self-propelled vehicle operating on a steam engine, representing the direct predecessor of the modern internal combustion automobile. These massive vehicles, equipped with large pressure boilers, played a vital role in the development of heavy land transport and agricultural mechanization in the 19th century, before being completely replaced due to low thermal efficiency and the long startup times required to boil water.
