Mont-Louis Solar Furnace

It was the first facility of its kind in the world, and was a precursor of the Odeillo Solar Furnace.

The French chemist Félix Trombe and his team made an initial demonstration of a mirror of DCA in Meudon in 1946 to show the possibility of reaching high temperatures very quickly using highly concentrated sunlight.

The goal was to melt ore and extract very pure substances to make new and more effective refractory materials.

A guide takes visitors to the heart of the facility to explain the operation and use of the solar furnace.

Applications of simple scientific and educational experiments complement the visit, for example: the concentration of the solar rays to produce temperatures between 2000 °C and 3500 °C (3500°F and 6500°F), the ignition of wood, melting of metal, and ceramic cooking.
