Résumé
A linear system with Fresnel reflectors as a concentrator was designed, built,and tested for solar cooking. It consists of 17 reflectors (blades) made of 1 mmthick aluminum sheet metal, mounted on a metal support to ensure theiralignment. The system has a geometric concentration of 17. The system is dif-ficult to operate because the blades must be individually and manually ori-ented according to the sun. A series of tests was conducted from May to Junein Ouagadougou, Burkina Faso, at a latitude angle of 12.21 ̊. Experiments in-volving 1.5 liters of oil and water in pots were conducted with and withoutglazing around the pots. On May 15, 2025, we obtained a maximum tempera-ture of 118 ̊C at 12:26 p.m. for the oil and 83.2 ̊C at 11:41 a.m. for the water.The experiments with glazing reached maximum temperatures of 112.5 ̊C at2:11 p.m. for the oil and 104.6 ̊C at 1:36 p.m. for the water on May 30, 2025.Spaghetti, rice, soy skewers, and fish dishes were cooked in a reasonableamount of time and ready for lunch.
