The steam engine can be considered as one of the most important
inventions of the industrial revolution.
In around 1712,
Thomas Newcomen built the first commercially successful steam engine to pump
water out of mines. A consequence of this was there would be almost an endless
amount of coal.
James Watt made
steam engines much more efficient in the 1760s and 1770s giving huge savings on
fuel. His other improvements meant steam engines could replace water and horse
power in a wide variety of industries, which in turn allowed factories to be
built anywhere.
Prior to this, most factories were powered using water, wind or
man. This was always seen as being
unreliable as you would not only have to be located near rivers but these could
also dry up due to droughts. It was also not always windy. On the other hand, steam power gave you the
flexibility to have factories located anywhere.
It also supplied trustworthy power that was used to operate machines,
this worked very efficiently. The steam engines used boiling hot water to drive
a piston back and forth. It would boil the water by burning coal (a useful
source of energy). When people used to dig to find coal, the holes would flood.
