'Fusion is the energy of the future, and always will be.' In the South of France, people are currently working hard at building ITER, the largest nuclear fusion power plant ever built. The ambitious project is a big gamble on the part of the countries that are funding and supporting it. Will this be the energy of the future or is it the biggest political and scientific gamble ever? Nuclear fusion - not nuclear fission - is seen by some as the ideal solution to the imminent energy shortage. Mila Aung-Thwin tells the haunting story - with clear and knowledgeable explanations of the scientists involved - about the ultimate quest for safe, clean and eternal energy: from the initial idea of Russian Oleg Lavrientiev, to the development of the largest core fusion center in France. But even outside of this center, the dream is being worked on: there are scientists working hard to uncover the secrets of nuclear fusion, for a fraction of the price, out of their own garage.
