Steam Engines

Another one of the great inventions that came about during the Industrial Revolution was the steam engine. The first commercial steam engine appeared in 1698. Then in 1712 Thomas Newcomen improved it. Although it was an improvement, it had many faults; including wasted heat and fuel. James Watt attempted to improve Newcomen's steam engine in the 1760's, and in 1785 he had done so, by using heat more efficiently with less fuel.
