The introduction of several advanced, efficient, and more robust power options over the years has largely overshadowed steam engine technology. However, it was a revolutionary technology that, upon its inception, helped power everything from a simple car engine to entire trains and commercial ships. However, steam engines had their own set of shortcomings, like its continual dependency on labor for operation, rising maintenance bills, and the emissions that were caused by it. Due to their complex operation and issues, most steam engines have gone out of use.

The technological advancements to the existing steam engine have led to several renditions of the technology, each a little better than the last. One notable advancement was the engine developed by American engineer Abner Doble. Considered robust and practical, one of the most unique elements of Doble’s design was that the steam from the exhaust was redirected to the main assembly to be converted to water, generating more power as a result. Plus, the system reacted to steam pressure as well as temperature, controlling the feed pumps and burner accordingly.
At one point, his inventions became so popular that they were equipped in steam cars and even buses. In the years following, several companies worked on the technology and came up with newer systems. For instance, the Sentinel Waggon Works’ water-tube boiler was a hit among railways for its design, where the tubes were heated externally. Similarly, the inventions of André Chapelon and Livion Dante Porta propelled the modern steam locomotives in the late 1940s and ’50s.
