The design was a great step forward from contemporary steam machine that used hydropower to return the piston and so could not be used if the hydropower was not available.
The machine was assembled in the winter and spring of 1766. But Ivan
Polzunovs tuberculosis became much worse and he died on May, 1766, at the age
of 37, three days before the machine was finished. The machine worked three
months, and then was disassembled despite paying off its costs in those three
months. A working model of the steam machine мейд by Ivan Polzunov is in the
museum of Barnaul and it still works.
