The Odeillo solar furnace, 54m high and 48 wide, comprising 63 heliostats, was commissioned in 1970 for scientific research. Following the first oil shock of 1973, researchers in the solar furnace turned their work towards transforming solar energy into electricity. With the return of energy and environmental concerns, the laboratory is again involved in the search for solutions concerning energy ...
