In my last blog I wrote about visiting a local middle school to give a talk on ‘What is Turbomachinery, and How Does It Work?’   The quiz at the end of the talk was for the students to list all the turbomachinery in their home. I had a few examples in mind to get the list started but was impressed with how long of a list we were able to generate after the students thought about it for a while. Since then the list has grown to include 40 items.   I will present those 40 below, but first let me repeat the assignment and the ground rules to see if you can think of more:


  1. List every piece of turbomachinery in your home.
  2. Inside and outside (in your yard is OK).
  3. Positive displacement equipment is OK to list.
  4. Don’t include turbomachinery in your cars or any vehicle or wheeled yard equipment (that’s another list…)
