The Steam Engine

Power and the Steam Engine.

Before Steam, we used wind, water and animals for power. Steam changed everything – great shovels full of it, whenever we wanted it, for how ever long we needed it.

Thomas Savery obtained the first patent for a machine powered by fire (a steam pump), and Thomas Newcomen added the piston powered by steam in 1725. Watt’s contribution, the double boiler, came in 1769. This made the machine efficient enough to generate real power and the move towards ever more powerful production facilities was on.
