In this episode – It Runs on Steam . . .
If you’ve seen Back to The Future III, you may remember Doc Brown's line, “It Runs on Steam!”

Have you ever considered how environmentally friendly a steam engine powered by renewable energy could be? There would be no need for gasoline, batteries, diesel fuel, or Uranium-234. Imagine an engine powered by water—yes, water. I can hear the naysayers: "But . . .”
Welcome back to On the Fly, where we dive into one of history's most fascinating inventions. Today, we're firing up a revolution – the Industrial Revolution, that is – with the mighty steam engine!
For centuries, people relied on muscle, wind, and waterpower to get things done. Then, in the 1700s, a series of tinkerers and engineers unleashed a new force: steam! Early engines were clunky and used to pump water out of mines. Then came James Watt.
James Watt was a Scottish inventor and mechanical engineer born in 1736. While he didn't invent the first steam engine, his work in the mid-1700s revolutionized it. Existing steam engines wasted a lot of energy. Watt introduced the separate condenser, which greatly improved efficiency and made them cheaper to run. His designs allowed the engine to generate more power consistently, making them far more useful for factories and other applications.
Watt also developed the double-acting engine, which could generate power on both the upward and downward strokes of the piston, further boosting its capabilities. James Watt's advancements in steam engine technology are widely considered a major driver of the Industrial Revolution. His work helped usher in a new era of manufacturing, transportation, and societal change.
Imagine that–no more limitations! Factories boomed, churning out textiles, clothing, and all sorts of goods at an unprecedented rate.
But the impact went far beyond factories. Steam-powered ships transformed travel and trade. No longer were journeys reliant on wind and weather. People and goods could cross oceans faster and more reliably.
And then came the locomotive! Steam trains ripped across continents, shrinking distances and connecting people more closely than ever. The steam engine profoundly impacted society beyond just increasing speed and efficiency. It led to the rapid growth of cities as more people moved there to work in factories. While new jobs were created, working conditions were often difficult. This period began a new era characterized by remarkable progress.
In hindsight, the steam engine wasn't perfect, but its impact is undeniable. It powered a revolution that changed the course of history. Despite the advent of electric and diesel locomotives in the mid-20th century, steam locomotives continued to be used and built into the 21st century. The regular use of steam locomotives in non-tourist revenue service concluded in 2024.
A dedicated community of steam enthusiasts keeps these locomotives running for historical preservation and enjoyment. Many historic railways, museums, and tourist lines still operate them.
So, while they're not hauling cargo across continents anymore, steam engines are still chugging along in a different capacity, reminding us of their revolutionary impact.
