Watt worked to develop other engines too on top of his revolutionary steam engine design. Notably, he worked on the rotary engine that replaced up and down piston movement with a rotary one.

James Watt would incrementally improve the engine’s design over the years. He added rotary motion and broadened the engine’s applications to uses beyond just pumping water.

Almost 200 years later James Watt, a Scottish inventor and mechanical engineer whose pioneering work with steam engines helped drive the Industrial Revolution, invented the first rotary steam ...

Air is drawn in via carburation or fuel injection through the front half of the engine, where it is squeezed down and compressed to 200-300 psi (13.8-20.6 bar) – very much like a compressor ...

Boulton & Watt Boulton & Watt, founded by James Watt and Matthew Boulton in 1775, revolutionized steam engine technology during the Industrial Revolution.

He promptly re-designed, re-built and made substantial improvements to the workings of his mother’s washing mangle. He also designed and built a ribbon saw and a prototype rotary steam engine. After ...

So it was for James Watt, whose Watt engine is often considered one of the cornerstones of the Industrial Revolution. This is why the watt is what we call the unit of power equal to one joule of ...

Perhaps the brand most closely associated with rotary engines, thanks to sports cars like the RX-7 and RX-8, the Japanese automaker is now interested in their use as a generator for vehicles with ...
