Steam Engine at Steamtown

Detailed Description

A steam engine at the Steamtown National Historic Site. Steam engines demonstrated one of the first comprehensive intersections of energy, mineral, and water resources. Steam engines required coal for fuel to boil water to make steam, as well as iron and steel for the casings and sand for traction on the rails. In addition, petroleum was required with differing levels of refinement for lubrication and other applications.
