Unlikely. No Russian can stay sober long enough to do anything like that.Officially, it is believed that James Watt ...
But, in fact, it was invented by the Russian Engineer Polzunov ...
Why?

Here's a list of all the things Russia has invented
That is all.
- Vodka
- 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:

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

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.
Polzunov's two-cylinder steam engine.
Replica of Polzunov's engine
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.

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.
