Odeillo solar furnace
The furnace consists of a large concave mirror measuring nearly 2,000 sq. m, which reflects sunlight onto a small focal point that reaches temperatures of more than 3,000ºC (5,430ºF). Opposite the mirror are hundreds of flat mirrors angled so that they reflect the sun’s rays onto the mirror.
It is used for several purposes, including melting steel, generating electricity via a steam turbine, making hydrogen fuels, testing re-entry materials for space vehicles, and performing high-temperature metallurgic experiments.
