Steam Power and the Metallurgical Revolution

Thomas Newcomen developed the first practical atmospheric steam engine in 1712, used initially to pump water out of mines, building on a primitive steam pumping device that Thomas Savery had already patented in 1698. Newcomen's engine, however, was extremely energy-inefficient, wasting most of the heat generated in each operating cycle. James Watt significantly improved the steam engine in 1769 by incorporating a separate condenser that dramatically boosted its efficiency, and he partnered with the entrepreneur Matthew Boulton in Birmingham, combining technical innovation with production capacity and industrial marketing; their factory at Soho became a reference center for manufacturing and selling steam engines across Europe.
