Development of the Steam Engine
1. There was a shortage of timber in the early 1700s in England, and the iron smelters turned increasingly to coal
2. Coal mines often flooded, and the steam engine began as a means to pump water out of the mine shafts (Thomas Newcomen, 1702)
3. 1763 James Watt began to make improvements in Newcomen's engine
4. At first the engines were so cumbersome that they could only be used as stationary engines, such as in mines and mills
5. Soon after 1800 the steam engine was used to propel river boats
6. 1820s steam engines used in moving vehicles
