I could go on but thats the basics. Vacuum has and is being used to do work. As shown below, the earliest steam engines operated on the principles of vacuum not press, and vacuum is often used as a clamp for glued assemblies. When overlooked, vacuum has also caused much damage as pictured in the second example below.
As an operating engineer my background is right but I always did better doing than teaching so here is a excerpt from "Mechanical Movements" on the early development of the steam pumping engine using vacuum.
