Steam engine. Historical artwork of a steam engine designed by the British engineer James Watt (1735- 1819) that was constructed in 1788. Watt revolutionised steam engines by designing a separate vessel for the steam to condense in. Previous engines, based on a design by Newcomen, condensed the steam within the cylinder which was far less efficient. Watt patented his design in 1769 and by 1772 had entered into a highly profitable partnership with Matthew Boulton in Birmingham. Whilst Boulton supplied capital, Watt continuously refined his design until his retirement in 1800.
