The thing which started us down the path to steam was, of all things, a pressure cooker. The Ottoman scholar Taqi al-Din came up with an idea for a steam-powered rotary wheel, which could be used as a water wheel. Leonardo Da Vinci wrote about an idea for steam-powered cannon. It would be more than 1,500 years from Hero of Alexandria’s aeolipile to the first practical steam engine.ĭuring that time other people certainly considered what steam could do. Imagine if steam-powered factories and locomotives existed in Ancient Rome or China.Īs interesting of an idea as it might be, the fact is it didn’t happen. This may be the subject of a future episode, but it is really interesting to think about. The evidence of the aeolipile so long before the development of the steam engine has for centuries made people wonder why it took so long to develop the steam engine, and if the industrial revolution couldn’t have occurred centuries sooner. As far as we can tell, it was basically a party trick. The thing is, they didn’t really do anything with the aeolipile. So, people knew very early on that you could do stuff with steam. The Roman architect Vitruvius had mentioned an aeolipile a few decades earlier, and that was probably based on the work done by an Alexandrian Greek by the name of Ctesibius as early as 200 years before that. While Hero is often credited as the inventor the aeolipile, he probably didn’t create the first one. When heated, the steam would shoot out the nozzles, causing the entire device to rotate rapidly. It is a sphere with nozzles bent in opposite directions sticking out, with the sphere attached to an axel to allow it to spin. The first documented case of using hot steam to create mechanical motion dates back 2000 years to the first century.Īn early engineer by the name of Hero of Alexandria, who taught at the Musaeum of Alexandria, built a device that was called an aeolipile.Īn aeolipile is a pretty simple device. It is perhaps a gross simplification, but I think it captures the spirit of what a simple steam engine does. This pressure can then spin a turbine or lift a piston, which in turn can be harnessed to turn a wheel or a gear to produce mechanical work. Because of its high temperature, this gas then exerts a pressure that can be used to do work. The water then turns into steam which is a hot gas. You boil water using some sort of heat source, which was usually wood or coal in the early industrial revolution. The concept behind a steam engine is pretty simple. This is most definitely true for the steam engine. It is a common thread in many of my episodes that things we think of as being recent inventions have their origins far earlier than most people realize. Learn more about the steam engine and how it was developed, on this episode of Everything Everywhere Daily. It was an invention that has its roots over 2000 years in the past. Yet, the steam engine wasn’t developed all at once. A device that could convert heat to mechanical work. The start of the industrial revolution is largely considered to have begun with the invention of the steam engine. The industrial revolution began the biggest change to humanity since the dawn of agriculture. The steam engine played crucial roles in the Industrial Revolution and westward expansion.Apple | Google | Spotify | Amazon | Player.FM | TuneInĬastbox | Podurama | Podcast Republic | RSS | Patreon Together, steamboats and steam-powered trains offered unprecedented speed and efficiency for travel, trade, and communication between distant parts of the country and world. Steam locomotives and railroad systems were created in England, but by 1830, inventor and industrialist Peter Cooper had designed the first American-built steam locomotive, called the Tom Thumb. The steam engine also transformed the railroad industry. In the 1840s and 1850s, steamboats also helped facilitate settlement on the West Coast, including California and Oregon. Steamboat routes emerged along major rivers, across the Great Lakes, in the Caribbean, and on transatlantic routes between the US and Europe. Following Robert Fulton’s successful demonstration of his steamboat, the Clermont, on the Hudson River in 1807, steamboats quickly became one of the most popular means of trade and travel in America. By the late 1780s, European inventors were experimenting with steam-powered boats and American engineers followed suit. The first steam engines were invented in the early 1700s in England and improved during the mid-eighteenth century. They revolutionized transportation and industry in the nineteenth century. Steam engines harness the pressure of hot steam to create mechanical power.
