The Steam Engine
The steam engine converts heat into reliable mechanical work. Its practical forms powered pumps, factories, railways, and ships, and are widely regarded as the prime mover of the Industrial Revolution.
Attribution — Built up over time by many contributors, often across different regions.
James Watt is popularly called the inventor of the steam engine, but Thomas Newcomen's atmospheric engine was pumping mines in 1712, and Thomas Savery had an earlier steam pump. Watt's separate condenser (1769) was a decisive efficiency improvement, not the origin.
What counts as the invention: Distinguish the first working steam engines (Savery, Newcomen) from Watt's improvements that made steam economical and widespread.
