Steam technology is an old but most valuable one in every country’s finances

To witness the incredible power of steam, you don’t have to look any further than the eruption of geysers or the explosion of gasses that occurs when lava reaches the ocean. Early man witnessed such sights and has long sought to control the raw power of
steam through technology ranging from the basic tea kettle to the modern nuclear power plant.

Regardless of the level of technology involved, steam power comes down to one basic principle: When water is heated to the point of vaporizing, the vaporized water takes up more space than the liquid water did. This is because solids, liquids and gases are
each held together by different levels of molecular forces. In solids, the molecules are compact. In liquids, they’re further apart. And in gasses, like steam, they’re even further apart.

If you heat a can of soup in a fire, the liquid contents will vaporize and eventually expand to the point where they will explode to release the pressure inside. When this pressure is used to perform a particular task — like turning a turbine or causing
a kettle to whistle — steam technology is harnessing steam power. The methods of heating, containing, channelling and using steam have changed, but the basic principle remains the same.

Learning to harness the power of steam has been a long process. Greek mathematician Hero theorized the use of steam technology in the second half of the first century. However, it would be well over 1,600 years before the first practical steam engine was
created in order to drain water from mines and gardens. The age of steam that followed shaped the course of history by powering the Industrial Revolution, transforming the global shipping industry and revolutionizing modern warfare.

Hero’s method for transforming steam power into motion was the foundation for later steam technology. However, a great number of scientific advancements were necessary before the concepts behind his steam turbine could be put to practical use. Although people
like Leonardo da Vinci toyed with the idea of steam power (the inventor suggested in 1495 that steam power could fire a projectile), advancements in engineering and more accurate measurements of temperature and time helped pave the way for the coming age of

In this article, we’ll look at how steam technology developed over the centuries and how our understanding of steam power changed the world.
