Who invented the steam engine?

Officially, it is believed that James Watt ...
But, in fact, it was invented by the Russian Engineer Polzunov ...
Why?

 

[Inmar]

Therefore, now, a unit of power is measured in Watts. But need in ползу-НАХ или ползунках

Why?

Unlikely. No Russian can stay sober long enough to do anything like that.

 

[Inmar]

No Anglo-Saxon has inventions, as they simply steal and officially register them. All the rest of the time they spend on breeding fleas, even in an ordinary American school ... and try to wash, because historically they never washed

Here's a list of all the things Russia has invented

1. Vodka
2. Discredited socioeconomic political systems

That is all.

Be sure and thank Polzunov. Otherwise, not sure why this matters.

Hero's Steam Engine
But still, Hero doesn't really need a lengthy biography to explain why he's important - his inventions and theories do that quite well. His most famous achievement was a primitive steam engine, which was known as the aeolipile. Others before Hero had mentioned aeolipiles, but he was the first to actually describe in any sort of detail how to make one, and it's unclear whether his predecessors had actually been talking about the same device anyway.

Here's how an aeolipile works. A sphere is positioned so that it will rotate on its axis, and curved nozzles are placed on either side perpendicular to that axis. Water is then heated, either inside the sphere or in a boiler underneath. As the water heats up, steam is emitted out of the nozzles, which creates force and torque that, in turn, makes the sphere start accelerating until friction and aerodynamic drag are strong enough to bring the sphere to a steady rotating speed. You can see a video of the aeolipile in action below:

Taqi al-Din Muhammad ibn Ma'ruf al-Shami al-Asadi (Arabic: تقي الدين محمد بن معروف الشامي السعدي, Turkish: Takiyuddin) (1526–1585) was a major Ottoman Turkish[1] or Arab[2] Muslim polymath: a scientist, astronomer and astrologer, engineerand inventor, clockmaker and watchmaker, physicist and mathematician, botanist and zoologist, pharmacist and physician, Islamic judge and Mosque timekeeper, Islamic philosopher and theologian, and Madrasah teacher. He was the author of more than 90 books on a wide variety of subjects, including astronomy, astrology, clocks, engineering, mathematics, mechanics, optics and natural philosophy,[3][4] though only 24 of those works have survived.[4] He was widely regarded by his contemporaries in the Ottoman Empire as "the greatest scientist on earth".[5][6]

One of his books, Al-Turuq al-samiyya fi al-alat al-ruhaniyya (Arabic: الطرق السامية في الآلات الروحانية)(The Sublime Methods of Spiritual Machines) (1551), described the workings of a rudimentary steam engine and steam turbine, predating the more famous discovery of steam power by Giovanni Branca in 1629.[7] Taqi al-Din is also known for the invention of a six-cylinder 'Monobloc' pump in 1559, the invention of a variety of accurate clocks (including the first mechanical alarm clock, the first spring-powered astronomical clock, the first watch measured in minutes,[8] and the first clocks measured in minutes and seconds)[9] from 1556 to 1580, the invention of an early telescope some time before 1574,[4] his construction of the Istanbul observatory of al-Din in 1577, and his astronomical activity there until 1580.

Seems there were earlier pioneers. But they never built a steam engine that would do work.

What a sad biography.

Ivan Polzunov - Wikipedia

Biography[edit]
Ivan Polzunov was born in the family of a soldier of peasant origin in the town Turinsk (currently Sverdlovsk Oblast region, Russia). After graduating in 1742 from Mining school (Горнозаводская Школа) in Ekaterinburg he worked as a mechanic's apprentice for the Chief Mechanic of Ural Plants Nikita Bakharev. Beginning in 1748 he worked in Barnaul.

In the library of Barnaul plant he found works of Mikhail Lomonosov, that he studied by himself as well as the descriptions of contemporary steam machines by I. Shlatter. In 1763 he proposed an original 1.8 h.p.(1.2kW) steam machine. The design used two cylinders on the same shaft that allowed its operations completely independently from water power even on dry places or in mountains. This design was a great step forward from contemporary steam machines that used hydropower to return the pistons and so could not be used if the hydropower was not available.

The project was sent to Empress Catherine II. She awarded him 400 rubles and promotion two ranks (to captain-poruchik) but did not seem to appreciate the new technology, as she recommended hydropower be used to return the pistons as done in Britain.

In 1765 Polzunov designed a large 32 h.p. steam machine for air pumps for steel furnaces. The director of Barnaul plants general Porshin agreed to use Polzunov's two-cylinder design as Barnaul steel mills were in a very dry area and in summer they often did not have any hydropower at all.

The machine was assembled in the winter and spring of 1766; the machine hall had very thin walls and a lot of draughts. Ivan Polzunov's tuberculosis became much worse, he coughed blood but still worked. He died on May 27, 1766 at the age of 37, three days before the machine was finished. The machine worked three months, then was disassembled and replaced by convenient hydropower, despite paying off its costs in those three months. A working model of the steam machine made by Ivan Polzunov is in the museum of Barnaul and it still works.

Polzunov only gets credits for the first Russian steam engine. Engines produced by Thomas Savory or G. Britain were being produced and used before Polzunov was born. Savory engines were used as early as 1698.

These threads claiming Russians invented all the things are laughable. They are the international equivalent of the white supremacists talking about white inventing everything.

Selivan, we get that you are Russian. We get that Russians invented stuff. But your attempts to show that somehow makes you better is ridiculous.
