The invention of a practical steam engine had an immediate effect on employment, first in Great Britain and later around the world. England had huge natural resources of coal that could fuel steam engines, and this drove the creation of mills and factories that turned out the goods that people had been creating by hand.he invention of a practical steam engine had an immediate effect on employment, first in Great Britain and later around the world.

The high consumption of coal which was common in Newcomenâs steam engine was reduced through innovations in engine design by James Watt. The low pressure engineâs cylinder contained heat insulation, a separate condenser, and a pumping out mechanism for condensed water.he basic principle on which the initial steam engines worked on was âcondensation of water vapor to create a vacuumâ. Thomas Savery and the First Industrial Engines. Thomas Savery was the first person to invent a steam pump for the purpose of pumping out water in 1698.
