Nice work THERMO ...you were born 300 years too late ..

This was the first useful steam engine in recent times , very simple ...

First steam under pressure pushes the piston up. At the top of the stroke , steam supply is shut off and cold water sprayed into the cylinder. Steam condenses causing a partial vacuum and atmospheric pressure pushes the piston down ... hence the name "atmospheric engine" ...

Trouble was , it wasn't very efficient ... when Watt produced his engine it was twice as efficient , and many atmospheric engines were converted to Watt types
