Robert Trevithick (1801)'s steam locomotive demonstration
George Stephenson's Rocket, 1829, would lead to great railroad infrastructure, which helped with city planning, made moving to the city easier, and made trade and large-scale commerce much better. For example, now placing factories in population centers made more sense. (I barely understand why myself, but okay)
Gasoline refinement
First occurred in 1850. Gasoline is an important fuel source.

More efficient thread spinning
Thomas Newcomen (1712)'s steam engine
