1. Everybody knows that the steam engine played one of the main roles in the industrial revolution. The steam engine wasn't invented but developed for over a century by three British inventors.

2. Thomas Savery was the inventor who built the first steam powered machine in 1698 in England. The machine pumped water out of coal mines. It had no moving parts and used much coal to pump water. Savery introduced the idea of using steam to perform a practical work.

3. Thomas Newcomen was the second inventor who improved the pump built by Savery. He added a movable pistol pushed by steam in one direction. The machine was used to remove water from a coal mine.

4. In 1763, the Scottish engineer James Watt brought enormous changes in Newcomen's invention. He was a talented person and since his childhood he dreamt of making things "work like a clock". He studied in London and then he returned to Glasgow where he began to make instruments for the Glasgow University.

5. In 1763, while repairing a steam engine of Newcomen's design, James saw that it could be improved as it was bulky and wasted a lot of energy. To condense the steam in the engine, Newcomen applied a jet of cold water. However, it also cooled the other parts of the engine. Its efficiency was less than one percent that made one of its main drawbacks.

6. Watt added a separate condensation chamber where the steam condensed without cooling the other parts of the engine. This chamber improved the efficiency by almost 75 percent. James Watt introduced the term "horsepower" to show how much work his steam engine could do. Watt also introduced some other changes in the engine that made it possible to convert a forward movement of the piston into a rotational movement. The heat engine could now turn the wheel of a mill or factory machine. Together with the businessman Matthew Boulton, James Watt started to produce steam engines, and they became very rich.

7. Watt presented some other important practical inventions like the double-action engine with both working pistons, a steam indicator that shows steam pressure, and a machine for copying sculptural works. James Watt died in 1819. In 1882, the unit of electrical power was named "a watt" after him.
