In 2005 a working group directed by Mr. Harmim of the URER/MS renewable energy center in Adrar, Algeria is developing and popularizing solar cookers in the Algerian Sahara. Posters and demonstrations at recent symposiums brought solar cooking to the attention of participants, many of whom sampled chicken, eggs, coffee and tea prepared in box- and concentrator-type solar cookers.
News and recent developments
- February 2009: Within the framework of a project of development and popularization of solar cooking in Algerian Sahara, registered in the program of the Unit of research in renewable energies in Saharan medium installed in Adrar (located at the south of Algeria), our team of research proposed the use of a finned cooking vessel with an aim of improving the solar cookers performances. Fins attached to the external surface of the cooking vessel increase the heat transfer surface area. This improves the heat transfer from the internal hot air of the cooker towards the interior of the vessel where the food to be cooked is placed. Indeed the various experimental tests carried out with the help of a double exposure solar cooker and a finned cooking vessel showed that there is a clear reduction of the cooking time in comparison with the same cooker tested under the same conditions but with an ordinary cooking vessel. The same results were also recorded with a simple box type solar cooker. An example of the finned cooking vessel is shown in the figure.
