The engine Calley and Newcomen created was a new version of existing technology. It combined several key parts in a clever way. It used steam cylinders and pistons to create power. They also used a method called surface condensation. This helped make the engine work more efficiently. They also separated parts that were usually placed together, which was a new idea.
