In this paper water vapor is directly generate in a short circuit by means of a compound parabolic troughconcentrator (CPC) while optimizing the manufacturing costs of the solar device used. Direct steam generation has beenwidely studied, especially for high power systems. However, experimental applications for small solar field areas are rare,especially for concentrating solar technology. This research shows that it is possible to produce water vapor with a CPC forcooking, dry cleaning, maintenance and cleaning, etc. The different heat exchanges that took place in each compartment of theCPC were described. The heat transfer equations were solved by the Gauss-Seidel’s method. An advanced difference scheme isused for the storage terms and a decentered scheme for the transport terms. The numerical simulation has been implemented bymatlab code. The different CPC parameters have been directly measure experimentally. The results show that for a CPC lengthLc=1 meter and width lc=50 centimeter, the theoretical temperatures of the water and the absorber can reach 125°C and 150°Crespectively, while the experimental temperatures of the water and the absorber are 108°C and 112°C respectively. Thetemperature of the water vapor measured can reach 110°C. The mass of water vapor produced with this device is 0.110 Kgwith a mass flow rate of 3x10-6 Kg/s and a saturating vapor pressure of 1.05 bar. The theoretical thermal efficiency reached is52% against an experimental value of 35% for a global solar radiation of 950 W/m2 and an ambient temperature of 43°C atsolar noon in April 2021. The CPC is designed to operate only during the day, and we are planning to add a heat storagesystem to our CPC for night use of the steam produced. In addition, instead of water, we can test the CPC's operation in thefuture with vegetable oils such as moringa oil
