Steam-powered vehicles are machines that use steam to create motion. They typically have a boiler that heats water to produce steam, which then drives pistons or turbines. This technology was widely used in the 19th century for trains and boats, significantly impacting transportation. One of the most famous steam-powered vehicles is the steam locomotive, which revolutionized travel and trade by allowing goods and people to move quickly over long distances. Another example is the steamship, which enabled faster maritime travel. These vehicles laid the groundwork for modern transportation systems.
