Tour d’horizon in Korea

Only for a few days but nonetheless: I could once again visit our project partners in Pyongyang.

Mr. Yang explains the progress of the project: The technical books “Stirlingengines” and “Stirlingmachines” have been translated, a copy of the “ST05 Viebach” has been manufactured and they are working on their in-house development of the Beta-Stirling for domestic production. At the end, I leave with a catalogue of questions for the Stirling specialists in Europe!

Eye Clinic
One morning I visit the Ryu Gyong-Eye Clinic with 102 beds that treats about 300 outpatients per day. Three years ago, Mr. Yang underwent glaucoma surgery performed by Dr. Kim who was still working at the Red Cross Hospital at the time and today is the director of the clinic. Mr. Yang is thankful that the operation was successful, “otherwise I would be blind today.” He has his eye pressure measured in the outpatient clinic where the referred patients from the regional hospitals are examined. The director explains that they have received new instruments but have no experience with them yet. Additional on-site training would be helpful. A wide-open door!

Visiting Doctor
I was very excited about going to the Red Cross Hospital and seeing our visiting doctor again.

The rheumatology ward has 50 beds and 25 doctors. Our doctor has finished translating the reference book and it will soon be printed. The microscope and ultrasound are being used – I encourage his supervisor to have him train others in using them. He would like further material and is open to inland-workshops. More open doors.

After a tour through the new Sci-Tech Center (similar to the science center we know and with many visitors) my colleagues had to run some errands. Having a car at my disposal was very useful and once again I get a glance of life in the quarters: streets with many sales booths, alive and bustling.

Stirling in Action

Our partner engineer in Pyongyang, is working to make a simple utilization of the Stirling engine possible for North Korean homes.

Now it is our task to provide North Korea with expertise on the „Stirling“. We are planning a workshop in Pyongyang. I will travel to Pyongyang in the spring for the preparation and discussion of the project progress and for a first hand impression of the Stirling engines developed by the Non-Conventional Energy Development Center.

I also hope to send another container with extra material to be used for training purposes.

200 Years of Stirling Engines

Agape international is supporting the Non-Conventional Energy Development Center in Pyongyang in the development of small Stirling engines for domestic and village use. The Stirling engine is a heat engine that operates with almost any heat source and provides mechanical work. Small engines like these can help alleviate the energy shortage for the population. We have planned a visit for this year.

The chief engineer, in particular, wants to meet with other Stirling engine manufacturers in Europe. We are working on the invitation letter, the visa applications and the visiting program.

We have already received helpful support from the work group Stirling-Motor in Munich that has been dealing with this subject matter for 30 years. Because Stirling engines are celebrating their 200th anniversary this year this topic is receiving additional impetus.

Robert Stirling was a pastor in Scotland and developed with his brother the engine that later became famous as the Stirling engine.

Electric Power and Heat

The past twenty years of collaboration between Agape international and the Democratic Republic of North Korea can be divided into two parts of ten years. We reported about the first ten years in our last edition of Our heart’s concern. In this edition we will focus on the second 10-year period.

In 2005 the North Korean government asked us to close our project office in Pyongyang. Therefore Agape international had to decide how the work in North Korea would go on. Without Swiss experts in the country, agricultural counselling was very limited. In 1996, thanks to a new contact with the Non-Conventional Energy Development Center (NCEDC) in Pyongyang, an area of activity apart from the food production was launched: energy supply. In the mid-1990s North Korea, as a country without its own oil fields but with coal mining plants, most of which were obsolete and some of which were flooded, was looking for alternative energies.

Wind as a Source of Energy

The first project was developing small windmills with the goal of using local material and knowledge combined with modern European technology. The first prototypes of windmills powered 300 to 2000 watt helped test technical challenges one on one. These small windmills can cover the needs of a household by producing electricity for light, TV and communication. In 2008, in the southern part of the country, the first 300-watt windmill was installed in the LPG Cooperative Samhun. For the first time it provided a family’s home far away from the village with electric power. In 2009 a 2000-watt windmill of the type Kukate was mounted and since 2010, on the island of Duru in the Taedong River in Pyongyang, the Kukate wings with rotor blades of polyester instead of metal have been turning by wind. Both windmills are providing electric power for about 20 homes.

Producing and Saving Energy

From 2010 on, the focus of the second project in collaboration with NCEDC has been saving energy. In North Korea as in Switzerland, there is a huge energy-saving potential in existing buildings in towns as well as in the countryside. The two seminars that were organised and lead by Werner H., PhD, on energy-saving constructions were very successful. There were more than 150 participants. After this three Korean experts published the first North Korean specialised book on this subject.

In Ryokpho, the vegetable cooperative about 15 kilometres south-east of Pyongyang, accessible in an hour’s bicycle ride by the employees of the NCEDC, two pilot scheme buildings were renovated and newly built for saving energy, according to energy-efficient standards by using the acquired expertise. Both buildings now serve experts from the whole country for further training.

Most of these activities were financed through private persons. Sometimes different organisations, namely the Swiss Development Cooperation (SDC), the German Agro Action (GAA), as well as GAiN Germany (baby food) help contribute to better nourishment, fruit growing and berry crop training.

What fascinates us about our job in this East Asian country is the open-mindedness of the people. Our Asian contacts, specialists and trainees are people like us, with ideas, emotions, wishes, duties and needs.
