I'm inclined to try to communicate it to Nert based upon your linking the two!

The Industrial Revolution seems largely the result of a particular positive feedback singularity, that the steam engine, which converts iron, coal and water into mechanical energy that can be used to pump water, was concocted in England, where high quality veins of coal and iron ore happened to be located deep underground beneath the prevailing water table. The steam engine pumping out mines, with steadily increasing power and efficiency, facilitated access to more iron ore and coal, which could be more efficiently transported by steam locomotives riding i...
