A Brief History of the Steam Engine
2009-09-02 07:00:00 The earliest steam engines, as developed by Thomas Newcomen and later improved by James Watt, utilized the condensation rather than the expansion of steam to perform work. Unpressurized steam was injected into the cylinder at the top of its stroke and allowed to cool and condense. This created a
