Selected Results of the 1994 ECSCR Comparative Solar Cooker Test and 1998/99 Tests in South Africa
(the following table was taken from page 30 of the gtz-journal. The 'Europea model' tested by gtz in South Africa has the identical mirror design as the AMSI-cooker)
Dimensions (cooking pos.): |
143 x 163 x 125 [cm] |
Dimensions (cooking pos.): |
1 removable pot (12 l) |
Test pot content: |
6 liter |
Aperture surface: |
1.54 m²(reflector) |
Heating time (water): |
|
Max. temperature (oil): |
*198°C after 130 minutes |
Continuous cooking: |
*boils 48 l of water in a day |
Heat loss with lid open: |
*cools from boiling temperature to 83°C in 15 min |
Comments: |
excellent thermal performance for a concentrator-type cooker; small |
Handling: |
easy, one-step access to pot; easy tracking, but level ground required; |
Application: |
cooker for large families and, in modular application, for small institutions; |
Evaluation for technology |
easily reproducible; reflector material must be protected against |
Contact address: |
easily reproducible; reflector material must be protected against |
Legend: |
*ECSCR; tested in SA; **European model, *** prototype built in SA |
additional experiences with the AMSI-Cooker in Ethiopia:
Usable Energy:
|
About 600 to 800 Watts (in Ethiopia) |
Maximum Temperature:
|
About 200 °C, dark paper is set to fire immediately, white paper after some time |
Time needed to boil water:
|
1 l of water in the traditional clay-pot (jabenna) boils in 8 to 10 minutes About 50 liters water can be boiled per day in a 10 liter black pot |
Overall cooker size:
Focal distance:Diameter of the mirror: |
80 cm / 160 cm / 160 cm |
Weight:

Arba Minch is a very good place to harvest the energy from the sun The insolation is 4.6 to 6.3 [kWh/m²/d]
Here you may find the solar-data about Arba Minch.
This is great compared to my plce here in Stuttgart/Europe with 0.7 to 4.1 [kWh/m²/d]
Here you may find the solar-data about Stuttgart.
