A picture shows the main building which houses the assembly area of the nuclear fusion machine "Tokamak" of the International Thermonuclear Experimental Reactor (ITER), during the launch of its assembly stage in Saint-Paul-les-Durance, southeastern France, on July 28, 2020. Thirty-five nations are collaborating in the ITER energy project aimed at mastering energy production from hydrogen fusion, as in the heart of the sun, a potential new source of carbon-free and non-polluting energy.
