Thanks for that Gary, I recently caught the documentary on ITER Project, an international collaboration:
"
In southern France, 35 nations are collaborating to build the world's largest tokamak, a magnetic fusion device that has been designed to prove the feasibility of fusion as a large-scale and carbon-free source of energy based on the same principle that powers our Sun and stars."
