Take a little water, add a little heat, confine it, give it a little time…(Nope, not yet, be patient.) Little more time, little more heat and…
BOOM! Pressure!!! Now what?
Oh I know, let’s use it to keep people warm and move things around – big, heavy things. Harnessing steam to power our lives is based on the simple idea of expansion. As water heats and turns to steam, the molecules are more active and take up more space and if we confine them and channel them in pistons and turbines, we can get those hyperactive H2O’s doing our bidding. Then once the piston gets going, we can utilize that force to drive our engines. And we’ve been doing that for a long, long, loooong time.
Steam power can be traced back over two millennia; yet not till the late Renaissance do we begin to find tested and patented designs popping up in Europe. But it was James Watt’s ingenuity, or should I say engine-uity, in the late 18th century with his continuous rotary-motion design that took the idea of expansion from microcosm to macrocosm. His invention was a driving force behind the Industrial Revolution and the world was duly and truly revolutionized. The steam engines that powered ships across the seas and trains across the continents brought the previously far-flung corners of the globe within reach. Our own American westward expansion owes as much to the steam-powered locomotives as the canvas-covered wagons.
But it’s this time of year that gets me thinking about the wonders of steam in a slightly different way. Because as I write this, toasty and warm during a season that’s anything but, I’m thankful we got some of that traveling out of our collective blood and bolted those boilers down. Heat, sssstteam heat, makes a man glad and thinking fondly of clanking pipes and popping radiators from a life lived before. And that at the end of all that expansion, we found a warm place to call home.
