the Odeillo solar oven it is a solar oven. His Strong (The word power is used in a certain sense in several areas 🙂 heat (Thermal energy production is a science dealing with its use…) is one megawatt. Along with the Parkent solar furnace in Uzbekistan, it is one of the two largest furnaces in the world the world (May refer to the word world 🙂.

This laboratory owes its world fame to its achievements scientist (A scientist dedicated to the study of a science or sciences and…) is unique in the field of solar way studies of phenomena temperature (Temperature is a physical quantity measured with a thermometer and…) and behavior materials (A material is a material of natural or artificial origin formed by man…) exposed to extreme conditions.


World symbolsolar energy (Solar energy is energy emitted by the sun directly or by radiation…) In France, the large Odeillo solar oven is located in the commune of Font-Romeu-Odeillo-Via in Cerdagne, in the department of Pyrénées-Orientales, in the Languedoc-Roussillon region. south (South is the cardinal point against north.) From France. The Odeillo site was selected for:

  • duration and quality of sunlight light (Light is a collection of visible electromagnetic waves…) direct (more than 2400 hours per year)
  • purity of sound atmosphere (The word atmosphere can have several meanings 🙂 (high and low altitude humidity (Humidity is the presence of water or water vapor in the air or in a substance…) average).

Nearby is the Mont-Louis solar oven and solar power plant (A solar power plant is an electricity generation system that uses…) THEMIS (THEMIS (Time History of Events and Macroscale Interactions during Substorms)…)In Targasson.


  • Temperatures above 3000°C can be reached in a matter of seconds, according to the process carried out in the furnace.
  • Energy is “free” and non-polluting.
  • This furnace allows us to obtain sudden changes in temperature and therefore to study the effects of thermal shocks.
  • There are no polluting elements (gas burning (Combustion is an exothermic redox chemical reaction. When…)…), because onlyobject (In general, the word object (from Latin objectum, 1361) refers to an entity defined by …) is heated to be studied and it is only a radiation (Synonymous with radiation in physics is radiation emission process or…). This heating (Heating is the act of transferring heat energy to an object, a…) can be done in a controlled atmosphere (eg empty (Void is usually defined as the absence of matter in space.) outer space, upper atmosphere of Mars…)

Operating principle

Operating principle

The principle used is the concentration of the rays reflecting the mirrors. The sun’s rays are captured by a first series of adjustable mirrors located on the slope, then sent to a second series of parabolic mirrors (“concentrators”). From there they convergent (convergent in cosmonautics, mathematics, convergent sequence convergent series…) to the circular target on top of the central tower; this target is only 40 cm wide Diameter (In a circle or sphere, a diameter is a line segment through the center…). It means concentrating the energy of “10,000 suns”.

The story

the chemist (A chemist is a scientist who studies chemistry, that is… science.) Frenchman Felix Trombe and his team conducted the first experiment in Meudon in 1946 mirror (A mirror is an object that has a surface polished enough to form an image on it…) DCA to indicate the probability of reaching very high temperatures very quickly environment (Environment is everything that surrounds us. All natural elements and…) very pure, thanks to the light Sun (The Sun (Latin Sol, Greek Helios or Ήλιος) is a star…) highly concentrated. The goal was to smelt the ore and extract very pure materials to make new, more efficient refractories.

To make it happen Faculty (The sector is a series of formalities, things to be completed before arrival…) and the first solar oven was set up at Mont-Louis in 1949 to test various possibilities. A few years later, based on the model of the Mont-Louis furnace and based on the results obtained, an almost industrial-scale solar furnace was built. In Odeillo. Construction of the Grand Four Solaire d’Odeillo lasted from 1962 to 1968 for commissioning in 1970.

This work was involved in the study of a thermal solar power plant to be carried out by EDF in 1983. This is the THEMIS power plant.experience (Experiment is the scientific method of testing through experiments…) It lasted from 1983 to 1986.

The closure (The term closure refers to:) of Themis solar power station (THÉMIS is a research and development center dedicated to energy…) It was supposed to be implemented between 2004 and 2007 to sleep (Sleep is a natural recurrent loss of consciousness (but without losing…) research on the conversion of solar energy into electricity. The Grand Four Solaire d’Odeillo laboratory is back in the spotlight activity (The term activity can refer to a profession.) on the study and development of materials point (graphic) industrial processes. Then the laboratory was called IMP (Institute of Materials and Processes).

With the return of energy and environmental concerns, the laboratory is once again involved research (Scientific research is primarily… energy and environmental solutions without denying their unique capabilities in materials and processes. PROMES (Process materials and Energy (Energy in common sense refers to anything that allows you to do work, energize, etc.) Solaire) – the current name of the laboratory – today, in addition to research on materials, it works on various systems for the production of electricity, hydrogen extraction with solar energy and various processes for recycling waste (including radioactive). .
