Watt refined the engine until it was efficient enough to run all sorts of machinery. Thanks to Watt, steam powered the first railway engine in 1804. He died in 1819 and the electrical unit, the ...

An engine indicator is an instrument for graphically recording the cylinder pressure versus piston displacement through an engine stroke cycle. Engineers use the resulting diagram to check the design ...

What seemed to finalize the impact of the Watt engine on the Industrial Revolution was his creation of the double-acting engine. Doubling the efficiency, it condensed steam both above and below ...

James Watt invented horsepower so he could sell his steam engine as the next great thing. Learn more about how it started, and how it's calculated.

Over at mises.org, Michele Boldrin and David K. Levine challenge the standard story of James Watt and the steam engine. Their conclusion: In most histories, James Watt is a heroic inventor ...

In 1712 Thomas Newcomen built an engine that made use of a piston, and, beginning in 1769, James Watt improved on steam engine design with a string of patents that included innovations such as ...

In 1763, working as an instrument maker at the University of Glasgow, James Watt was assigned to repair an early steam engine. Watt was intrigued by the idea but noted the machine's inefficiency.

Naomi Alderman tells the story of James Watt and the steam engine that nearly never got made. A breath of steam hits cold metal. It cools suddenly and becomes a drop of water. There an idea. But ...
