If we asked when the steam engine was first invented, we would probably guess that it was in the 18th century, in which the Industrial Revolution began – its invention marked the beginning of a new era: its influence was so great, even though it had been around for so long that it had been Technologically, on the basis of the steam engine, and a very specific aesthetic, a modern subculture, the so-called Steampunk, has also developed.
Something unimaginable about the pyramids of Giza and Greek temples has come to light, which until now only the most daring had thought of.

He may be right, but more than a thousand years ago, that is, shortly after AD. After 0, the Hero of Alexandria described a type of steam engine used for an unknown purpose. The structure is a simple steam turbine that rotates when a water tank is heated:
“It follows that when the boiler is heated, the steam falls into the ball (atmes) […] It falls through the curved backs (small tubes) on the lid and spins the ball, just like dancing characters.
– Written by the Alexandrian hero A. Hieron (a fully detailed 19-page study of the structure in English) here readable).
According to the accounts of the most famous ancient historian, there were giants, and he writes about them in detail in many of his works

Although it was a very impressive device, you could probably use it to impress everyone in the Agora Ancient Greek Your friend, in terms of actual usefulness, the mysterious object was not exactly among the indispensable things:
“The Heron device is an inherently weak design to produce usable energy.”
– Written by Paul Keyser A new look at the Heron steam engine In his book, which investigated machine operation.
“Because of the rotator cuff […] Or there is excessive friction or excessive leakage, and in both cases it reduces the efficiency of the device. The ball will not have enough inertia to provide consistent power under different loads (i.e. weak flywheel) and will spin too fast (over 1000 rpm) to transfer power using simple reduction gears.
Instead, Keyser calls the engine—a far cry from real steam engines built centuries later—the first demonstration of rocketry and reactive power.
So what was its purpose? What is disturbing is that Heron has remained silent on this issue, leaving it to speculation. It is believed that this structure may have been used as a novelty to amuse and amaze citizens in ancient Greece – so it seems that the Greeks were indeed ahead of their time in many ways. In addition, aeolipile (structure noun) can also be used. Performing miracles in churches.
