Arezki Harmim is a master in renewable energies and directs a three-person research project for development of solar cookers in the Algerian Sahara. A working group directed by Mr. Harmim Arezki, of the Research Unit in Renewable Energies in Saharan Medium (URERMS) in Adrar, 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.

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.

• May 2024: Arezki Harmim reports: "Part of my participation in the Fifth International Conference on Advanced Mechanical Technologies SITMA24 at Abu Bakr Belqaid University in Talmasan, where I had the honor of meeting my dear friend, the director of Talmasan University, Professor Murad Megasho, and an elite group of professors headed by Professor Abdul Karim Lizid, Belqasim Adwan, Belqasem Darawi, Saim Rashid and other fellow researchers. I had an oral intervention in which I presented some of the results of the research work on the development of the hybrid PV-T solar cooker that can be integrated into the building wall."

• April 2016: the Research Unit in Renewable Energies in Saharan Medium (URERMS) of Adrar (Adrar is located in the Algerian Sahara), affiliated with the Development Center of Renewable Energies (CDER) of Algiers, organized the first Adrar solar cooking festival. The festival was programmed within the framework of solar cooking development project conducted by Arezki HARMIM, Mebarek BOUKAR and M'hammed AMAR. This goal of this event was to contribute to popularization of solar cooking. The festival consists of grouping young pupils of Adrar for a competition to construct their own solar cookers for the public; guests get to see the various achievements and appreciate the taste of solar cooked food. Introductory solar cooking courses for the construction of a simple box type solar cooker have been offered since December 2015. In total, 179 pupils took part in the festival and presented 70 solar cookers of various forms and designs with various construction materials (wood; cardboard; newspapers; sawdust; dry fiber taken on the palm tree; glazing; mirror; and aluminum foil). At midday, the guests (parents, teachers, pupils, researchers, and other visitors) were invited to inspect the pupils' solar cookers and taste the chicken breasts (40 kg) cooked in the various solar cookers. In a friendly and festive atmosphere, the children were able to discover solar cooking and were enthralled by obtained results. At the end, an awards ceremony was organized to honor all the participating pupils.

• 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.
