Warming up! 30 years of fusion-energy research at EPFL
The intense heat and pressure inside stars, such as the Sun, cause pairs of atoms, especially hydrogen atoms, to come together or 'fuse'. When these light nuclei merge into a heavier nucleus, some mass gets lost and is converted into a massive amount of energy, following Einstein's famous formula, E=mc2. This fusion process is what powers stars and releases an incredible amount of energy into th
