The steam engine was invented by Thomas Newcomen in 17121. It was a very
             important invention and helped give way to the Industrial Revolution. It was very useful
             invention of his time. Many people like James Watt and Richard Trevithick used the
             atmospheric steam engine to produce more sophisticated inventions.
             Thomas Newcomen was a very important inventor. He was born in 1663 in
             Britain. He worked as a blacksmith until he worked with Thomas Savery, who had
             already tried to make a steam engine but couldn't do it.
             Thomas Newcomen invented the first working steam engine in 1712 with the help
             of Savery. At first the steam engine wasn't very popular, later the steam engine was
             considered the century's most important invention when used in mines.
             Thomas Newcomen also made tools for coal miners and often visited mines, this
             is how he knew the needs of miners2. The first steam engine was used to work at a South
             Stafforshire colliery3. Most of the early engines produced the steam by using coal. This is
             why steam engines were installed in coal mines where coal was free.
             Even though Thomas Newcomen actual invented the first steam engine, James
             Watt is usually known for making it4. Watt's engine was much more efficient than
             Newcomen's because it prevented the loss of steam. Watt started out repairing
             Newcomen's engines, and then began making major improvements to it.
             James Watt's engines were much larger than Newcomen's with a larger cylinder
             which pumped more water out of mines5. His engines were designed with a rotating shaft
             and a flywheel which was more sufficient. Later he further improved his engines by
             adding another condenser and cylinders. He also added throttle controls on his engine to
             control the rate that the engine pumped water.
             Without Watt's study in the field of mechanics, the steam engine might not have
             been made, and the industrial...
