He is a good man James Watt James Watt, was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. His connections is he repaired a model of newcomen engine and cooled the steam while it was creating less wasted heat.

The first modern steam engine was developed by James Watt (1736-1819), a Scottish engineer, in the 1760s. Building from the earlier steam engine developed by Thomas Newcomen, Watt made several significant improvements to his predecessor's model. Watt's key enhancement was a separate condenser which helped to solve the massive heat loss and resulting inefficiency which characterized Newcomen's model. In Watt's model, a cylinder head forced the piston down in a partial vacuum by means of steam. Watt finished his model in 1765, and the first steam engine of Watt's design came out in 1769, the same year Watt's idea was patented. Watt took some of his ideas from another inventor and engineer named Humphrey Gainsborough (1718-1776).
