Steam engines were invented to solve the problem of getting water out of coal mines so that more coal could be mined to feed the steam engines. Pretty soon, all the coal was gone.

As a qualified chemical engineer I shall now embark on a proper explanation of the complex thermodynamics processe involved. No wait, I've forgotten it all. Maybe HyperD is a bit younger.bloggoth

Condensing engines relied on atmospheric pressure and had horrible (in later steam terms) efficiencies, admittedly in the days of low pressure steam the ability to make good tolerance cylinders, pistons and valves was limited. Sub 10% efficiencies is normal for these engines and the whole engine has to be massive.
Steam engines got really effective with double and triple expansion engines that recycled the waste steam from first to second then second to third cylinders, plus of course the engineering and materials had developed a lot. 30-50+% efficiency isn't uncommon for triple expansion.
There are loads of working static engines in museums around the country plus the railway and traction engines of course, interesting to look at if you like engineering.Comment
