The fact that the people of Waknuk are so proud of their steam engine, and that there is not another one for 100 miles, illustrates the extent to which technology and engineering has regressed since the Tribulation.

Not a great deal is said about the Waknuk steam engine, but it was probably of the type invented by Thomas Newcomen in 1712, principally used to pump water out of mines.
