This is a modified version of Mr. Kleinstein's model of Watt Steam Engine. He created an amazing model and submitted it to Lego Ideas in 2018. Unfortunately, his design did not get enough votes. Later, Kaero created instructions and made them available on Rebrickable.
The instructions helped me to learn the main ideas and make a modified version. My model is more compact, uses a smaller brickmade flywheel and a modified transparent cylinder + valve.
It is possible to drive it by a home vacuum cleaner but the rotations are not stable enough. That is why I use a PF motor in the video.
