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):
- cold start (40 - 80°C)
- cold start (40 - 96°C)


*27 minutes/**27 minutes/***30 minutes
*44 minutes/**38 minutes/***39 minutes

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
nominal pot content for this size of aperture; requires regular tracking

Handling:

easy, one-step access to pot; easy tracking, but level ground required;
acceptable operation, but difficult to relocate

Application:

cooker for large families and, in modular application, for small institutions;
suitable for cooking and roasting

Evaluation for technology
transfer/local production:

easily reproducible; reflector material must be protected against
corrosion; a folding type of steady stand is under development;
transport and assembly require optimization
