Stirling Engines used in Physics Classes

During my September’s traveling week I visited some companies and cooperatives. I already reported about this in our October Newsletter and will now add some more impressions and experiences.

It is a meaningful moment when our chief engineer presents me with the newly published Stirling book. The translated title is “External (Stirling) Combustion Engines – Theory and Application.” It is a compilation of the European know-how that we have conveyed to them in the last three years.

Second highlight: I learn that they have reconstructed five Stirling models so that teachers can demonstrate their function and operation in physics class.

First, I visit the machine tool factory that produces the models: This factory with 450 employees was founded in 1958 and at times is to have produced 20% of the machines and tools in North Korea. The work is still done on traditional workbenches, without CNC.

Then, we go to a school. The middle school of the Pyongyang orphanage is the recipient of some models. A staff member takes me around “officially”. This happens very businesslike: everything is predefined for the children, what they eat, how much, how hard or soft the beds, the pillows must be … thanks to modern IT the complete school area can be monitored, which includes the classrooms. This is to ensure the high quality of the lessons. The school is connected to other Schools by the state net by which they share their insights among each other. (I read: “Latest post: No student is too dumb to be taught.”)

The atmosphere becomes considerably warmer after the director and the physics teacher join us! They are excited about the practical demonstration material, the accompanying instructions, and books. They start working the models and look forward to the students’ reactions.
